    I have a 2012 X1, I had heard the timing chain whine get worse over the winter, so I parked the vehicle the end of May, and slowly ordered the parts and the timing chain lock out kit for my mechanic. It was a good thing I did, I was talking to him the other day and he said the the top right timing chain guide had failed and was just kind of floating around. I was lucky I didn’t lose the engine. He said there were bits of plastic in the bottom of the oil pan. It was thanks to this blog that I was able to save my X1, hopefully I won’t have anymore issues with this!

    I have a 2013 328i with 85k miles, mostly highway if that makes any difference. At 77k miles, I got a low oil pressure warning light, towed 100 miles to the dealership and they couldn’t find anything wrong. Eventually replaced some kind of oil flow/distribution sensor of some kind as a starting point.

    Serviced at 80k as usual, with nothing appearing. Also took it in at 84k for a $150 diag fee because I could hear a whine, but since I was reading all of these threads, I wasn’t sure if it was just me worrying. Sure enough, 85k lead to another Low Oil Pressure warning light. Towed to BMW dealership, and 4.5 hours of labor to find out that the Timing Chain guide was broken.

    Dealer originally quoted $4700 for repair, which included some BMWNA assistance apparently. I called BMWNA directly to escalate and hit a brick wall for 10+ minutes, no help whatsoever. Apparently, extended warranty is their ‘sorry’ and any other issues after this is just wear and tear. Eventually the dealer lowered to $3700 because of my loyalty in giving them too much money, (Taken the car there since I got it 2 years ago at 45k miles)

    The question I have, is what questions to ask? I have researched as much as I can, but want to know what else to ask to be replaced whilst they are in there. Oil Pump? Oil Pump Chain? Anything else?

    The notion that these problems are isolated isn’t true – the SA spoke about the frequency of these (mainly X3’s).

    I understand the risks of owning a BMW compared to a generic car, but to think that another four-figure repair bill could pop up is nerve wracking to say the least. Unfortunately, I put way too many miles into the car which had lead to me being upside down in it anyway compared to my loan. Stuck.

    • No I really can’t think of anything else they should replace,,,,they should replace the timing chain and guide rails and oil pump chain and guide,,,,,it’s up to you if you want the oil pump replace at the same time,,,,they will be inside the oil pan when they do the other work, it would only be a couple more bolts to replace at that point

    Hello – I stumbled upon this page and am so appreciative. I started getting this whine and saw your post and the SIB you posted. Took the car to BMW as I am almost at 7yrs and at 65k miles, and they said I will get the SIB 11 03 17 as outlined above. Car has been in the shop for a day, and tech said they’ll let me know if they see anything else, while they have the engine open. I understand they will replace the timing chain and guide rails and oil pump chain and guide. But I want to be smart when they call me and try to hit me up with other non-warranty issues. What else could they possibly find that may not be covered due to this issue? I suppose they could suggest I change the oil pump? What would be a reasonable cost while they are in there, and is there any reason to change it? I suppose I want to be smart and not let the dealer fleece me while they are at it. Any advice is appreciated and thank you for your good work.

    Driving bmw 2013 x3 i28 to work. Stopped at traffic light and car indicated “drivetrain malfunction, with low oil pressure warning. I immediately stopped and had car towed to bmw dealer. The SA drove the car into BMW repair shop and promised calling the next day. Bmw called and told me the engine needs to be replaced. They said the timing chain guide had broken and pieces of plastic found in bottom oil pan. I bought the car at 72,000 miles from another dealer and currently at 100,000 miles. I have always changed the oil as recommended. I am thinking of taking it to a mechanic. The engine still runs and car starts but I don’t want to drive it. Any advise will help. Why does the dealer want to change the engine at $13,000? Am still financing the car and it still looks like new. Besides I can’t afford a new engine.

    • I think the dealer want to replace the whole engine because they are worried about anymore possible damage that was done to engine when it loss oil pressure,,,,BMW doesn’t want to take the liability if they only replace the timing chain and something else is wrong,,,,,it’s easier to replace the whole engine,,,ok if the engine still runs I would then have it towed to a good known independent BMW mechanic who has done this repair before and that can lead you in the right direction

    I had timing chain issue and dealer replaced the timing chain drive and oil chain drive module where 50% of cost was covered by BMW Canada. Car was out of warranty but had only 55000 KM on it. Now that timing chain drive and oil chain drive has been changed, do I need to worry about it failing again or the new part fixes the issue?

    Hello. I hope you will respond to this. I have a 420i N20 build date summer of 2014. I’m very worried it’s a second hand car I do hear some rattle at cold start but I’ve come to understand it’s “normal” until the oil pressure is there to support the chain tensioner. I have read around the net and my research seems to confirm that the tensioner works under pressure so at cold start you can hear a little rattle. I called my dealer about this too and he said that as long as it at cold start and only lasts a 10 to 20 seconds there’s no real worry, I should be hearing it when its warm. So uhm, just to be sure I’m asking you too… Should I get my chain tensioner / guides replaced ? my car has 50k KM on it. I drive it around in the netherlands area.

    Thanks.

    quick question, I just did an oil chain to my 2014 F30 N26 xdrive and was checking the timing chain, I used a pliers and was able to pull the chain up to about 2~3mm. Read on other forums that it is normal while the engine is off, please correct me if I’m wrong, N26 have 50k miles.

    Yesterday (my 39th birthday) I was driving home from being out of town at a company event. 77mph in a 70mph zone, low oil pressure warning came up. Stopped as soon as I could and had it flatbed towed to the nearest indy shop – who just called and confirmed it’s the timing chain guide issue. The engine did re-start, didn’t sound bad at all (didn’t drive it at all) and I didn’t get the “drivetrain malfunction” warning.

    Called BMW NA to learn what they can do. In short, I have to pay to get it towed to the nearest dealer, where they’ll “diagnose” the problem. I’m praying it’s not a total engine swap. Thanks to this thread, I learned about the 7/70 extended warranty. Problem is, I’m at 70,800 miles….

    Anyone ever hear of BMW helping people just outside the extended warranty period? (fingers crossed!)

        Just heard from the BMW tech at the dealership – he’s advocating that this gets covered under the warranty since I’m only 800 miles outside of the 70k and well within the 7 years. My timing chain is loose, but they don’t know why that would cause oil pressure drop. No evidence of engine failure, but they said I’ll need an oil change, alignment, and oil pump (well over $5-7k). I contacted BMW North America and left a message with the case manager (Jason). Any idea on whether they’ll cover it??? Any idea on how a loose timing chain would cause oil pressure drop? It’s not showing an oil pressure warning anymore, oddly….

    Hi, I am interested in buying a X3 xDrive28i built in 11/2012 which currently has 76K Miles on. The following parts were replaced:
    In 7/2017: Serpentine belt
    In 11/2017: Central valve (2), timing chain, slide rail, tensioner guide rail, valve cover gasket set, oil pan gasket, chain drive, front crank seal, axle bolt (2), hose, sprocket, o-ring (2), bolts, oil housing gasket
    In 4/2018: Alternator Rebuild and battery
    In 4/2019: AIr intake hose & breather hose
    In 3/2019: Drive belt(s) replaced
    In 6/2019: Found & secured Vac line for charge pipe
    In 7/2019: Engine/powertrain computer/module checked, Drive belt tensioner replaced, Drive Belt(s) replaced.
    1) It looks like the timing chain was replaced in 11/2017, apparently from the owners pocket (why?), but I am not sure if other recommended replacements were done. For example I cannot see the replacement of oil pump chain and guide in any records. Anything left to worry about?
    2) Looks like they had some issues since the beginning of 2019. Looking at the replaced parts, can you tell what might have been the problem? Drive Belt(s) was replaced twice in 4 months for some reason (first by a local repair shop, second by BMW dealership). Do you think these repairs in 2019 indicate more potential problems?
    3) The car seems to be in a great shape, however do you think I should be concerned about this purchase -based on the above information? What would you recommend?
    Thanks in advance.

    We can all guess why the USA issued a recall while other countries didn’t. Could it be the ethanol fuel in the US? The ASS adding regularconstant tension in a routine trip? Could it be the prevalent chipping of vehicles in USA causing stressed engines? Could it be the somewhat preference to high RPMs in the USA?

    Turned on the X3 one evening to a MASSIVE rough idle. Not a cute rough idle, but one that can throw your back out and jarring-to-the-joints rough. Took it to an independent shop who saw multiple misfire fault codes: on every individual cylinder as well as simultaneous, plus VANOS. Suggested the car “jumped time” and could need an engine swap. He noted BMW NA is providing engine swaps for $2500-3000 through a “betterment” for customers. Any validity to this? Based on the comments on this thread, I think he’s off by $10K or so.

    Further recommended I take to a dealer. Dealer provided its diagnosis which ended with “Refer to SIB 11-03-17” which I have found and read on your website. My concern is that the engine is shot, and this repair will not suffice. Is there any validity to this concern? Dealer quoted $7400, but offered me a “discounted warranty rate” of $4800.

    Hey bmwtech, question I’m 4 months out of warranty but at 96k and the engine never locked up. I just had my 2012 bmw 328i f30 n20 diagnosed at my expense at the dealership while getting an oil change. They recommended I replace the rod bearings without opening it just by the sound of the engine. They did recommend I replace the battery which they said was part of the problem. I took it to a second shop that is a bmw repair shop that works on bmws and minis. They found oil pump chain guides in the bottom of my oil pan. The shop is quoting me 6k for used engine and 10k for a new. Do you think BMWNA will have any goodwill if I go after them to help replace the engine? What would you do?

    I just wanted to thank you for posting this information. I am learning a very hard lesson with a Porsche Cayenne 957 I purchased at auction without first researching the model. I’ve now learned those cars are basically garbage. Fortunately, I’m handy with a wrench and have been able to remedy a lot of problems (cleaned carbon cake from intake valves by hand, fixed leaking cooling system and replaced thermostat, replaced coil packs, and et cetera). There are two outstanding problems I can’t fix on my own without a shop – replacing front differential and rear main seal. I’m figuring those will be spendy fixes.

    Anyway, I came across a good condition 2013 328i Xdrive at auction. If I understand BMW paralance, that’s a 2013 F30 with an N20 engine. I’ve been researching known problems with the model and was reading up on concerns regarding reliability with the timing chain and related appurtenances. The vehicle I was looking at was manufactured on October 2012, so it would fall under the above TSB. I think I will save myself the potential hassle and simply steer clear of this model.

        Hi Andreas, same here I was delighted by a mint 2013 X3 73k miles with good service records, selling at a reasonable price, I took some videos of how the chain looks and how the engine sounds, I did not hear a wizzing sound but I may be wrong. I did stuck my finger trying to feel any slack in the chain but it appears to be normal, i could hardly move it from side to side. I have also read that there is a low percentage of these engines that fail, however, there is no actual data. What do you recommend in this case ?

    Hi Bmw tech!
    I’m in canada looking at the 428i. I have an option of 2015 and 2016. Both have eveything same! Mileage, colors, features, but the price is a big difference. About 6k more for the 2016.
    My question is, should i go for the 2015 model and buy 3rd part warranty? Because that 2015 model was manufactured in 2014 do it might have the timing chain issue for sure. Awaiting your response!

    120408 boost pressure control, cut off pressure rise blocked

    I took it to bmw dealer ship and they told me
    they need to replace my serpentine belt and tensioner
    they are removing and replacing engine oil filter housing and gasket…
    so i called them a lil while ago to check in and also to mention
    sa 111315 to see if i would be covered for the engine oil filter housing and gasket.
    she took the info and looked up the service action and said she would bring it up to the tech. so hopefully i don’t have to pay for that.
    she told me that they will be keeping my till Monday because they are still diagnosing and they are going to replace my timing chain under the sulev warranty

    I have a 2012 BMW 528i. It developed the whining noise that slowly manifested into louder screaming noise.

    Two weeks ago, the car stalled when I slowed down at an intersection for traffic signal. I was in the center lane and there were cars behind me. My immediate reaction was to turn in the hazard lights. The display screen showed either “Drivetrain Malfunction” or “Transmission Malfunction” very briefly.

    Being I was in the middle of the road, my second action was to maneuver the car and steer it away from the road. When I looked around and when it was safe to do so, I happened to see the warning go away.

    Presumed that the “Drivetrain Malfunction ” error would be logged. But, no, the system had different system error codes (checked on the speedometer), but no check engine light or other vehicle status warnings.

    When I took it to a authorized service center, I was told it is a very common problem and BMW is well aware of the issue, but never told there were some vehicles with voluntary recalls, issued by NHTSA. I believe there is also a class action lawsuit.

    In order to proceed with my daily livelyhood I agreed to service the car at about $5000 plus another $650 for other fixes.

    Had only I had been warned by BMWusa, of this known defect, court order and the voluntary recall, I would have done everything to address the matter within the stipulated time frame.

    The whining noise did exist for about six months, but no warnings of any kind.

    I wish to kno what can I do to recover the repair costs?

    I am not talking of failed batteries, a light bulb, even cracked disc brakes, or things of the nature that nobody can predict the reason for failure. But the timing-chain issue is well known and not providing me the necessary recall information shows unethical business practices.

        I have proactively checked recalls on my car by entering the VIN number on their website, which said all the warranty has expired three years ago.

        Please help others by lodging a complaint at http://www.nhtsa.com. NHTSA is requesting that we complain so they can have this addressed appropriately. N63 and N47 engines have been recalled, N20 and N26 are in two lawsuits, pending court order, but NHTSA needs to know so they can act.

    All,

    Reach out to the attorneys who have filed a Class Action Lawsuit (CALs). File a complaint at NHTSA with all the relevant information. It does not matter if BMW extended the warranty to 7y/70k and has expired on your car when there are open CALs specific to the timing-chain malfunction.
    NHTSA has issued a bulletin pertaining to N63 engines, so it was a voluntary recall. NHTSA will revise the recall to cover for N20 and N26 engines if they get more complaints and incidents from users like us. Our cases are not frivolous, but a genuine case of withholding of information by BMWUSA. I did neither receive the letter of the warranty extension or any recalls nor see the extension on MyGarage page on my account. Recalls for N20 are inapplicable yet until court directive, but if it is N63 BMW has to have sent the notice.

    I called NHTSA today and so far they only have a couple of complaints pertaining to the timing-chain problem. There are 68 other complaints related to power-braking and an investigation is launched for only that.

    Most of you know by now that BMW extended the warranty on timing-chain only to 7 year/ 70k, but failed to have sent letters to all the owners.

    This timing-chain is a universal problem and I seriously insist that a complaint be filed so an investigation can begin.

    Can you take a moment and go to http://www.nhtsa.gov and write up a complaint of when your issue occurred and what you have done about it.

    It takes less than 5 minutes and is very very straight forward – enter VIN number (it is available online on your insurance declaration page), select “Engine & Powertrain” as the affected components and type in the incident.

    Also contact KKG Law office and talk to the paralegal about your issue.

    Threw a code yesterday, P052B ” Camshaft Position Timing Over-Retarded” Car went into limp mode but was overall fine. (In the past it did randomly throw the Drivetrain Malfunction warning but would go away away on its own, not sure if related)

    Dealer today said the timing chain and some pumps needed to be replaced? and once they do that they will see how engine looks and whether that needs to be replaced as well. I was blown away before I started reading that this is a common issue.

    I’m out of warranty so I said I’ll be taking it to Indy shop for a 2nd opinion.
    My question, could this code have been early signs that the chain was about to break and is best case scenario just replacement of the belt?

        With respect to the PCV valve cover, I believe the membrane could be ripped. ASC said whole valve cover needs to be replaced and it takes a whole day as sometimes the problem could be with the intake manifold, which would be automatically be covered within the 2year/20k extended warranty on this issue. I really don’t trust them, since they didn’t tell me these issues were present during the inspection and diagnosis when I took it for the N20 chain issue. I do know there is no way to say all that is wrong with this car, but it upsets me that after spending $5000 I have another $2000 repair pending.

        Some YouTube videos show the cap of the valve can be sawed off and replaced. I wonder if there is a glue remover solvent, can we just try to do that rather than sawing off the cap? Also, I don’t want to go about this route to know that in six months something else happens.

        I am responding to a different topic here. I had my car in at the ASC for the timing chain issue which cost me $5600. After this, the car developed other issues which they either goofed up or is my misfortune and repairs for the same would cost another $3000: driver seat back panel dislodged, AC blower fan loud, PCV valve whistling noise at start/stop. I took it back and these guys said whole seat back panel, AC blower fan, PCV valve cover needs replacing. The technician could not find the whistling noise even after a week of diagnosis and repeated attempts. They didn’t even turn the engine on or take the car out for a week. They had me come over, take it out for a 10 minute drive with the technician and show the problem. I even had sent a sound recording of it previously. They kept the car for another week and said the whole valve cover/lid and pressure hoses need replacing.

        I checked a few videos online about the PCV valve cap, not entire cover/lid replacing. Incidentally, on my car just the cap will easily come off. These guys wanted to con me for $1700, for a $17 + $5 shipping. This cap need not be sawed off on my car, as BMW has changed the design and only requires cap replacing. My 10 year old did it for me.

        I caution all owners to first open the engine cover and then go about getting it fixed or fixing it yourself. Don’t trust the ASC as they have no ethics. I can share images of what I did and part I replaced if anyone needs.
