    • The only way you would know if your engine was making some abnormal noises,,,or if they found metal shavings in your oil filter,,,,there is no other way.

      my wife owns a 2013 (maybe a 14) BMW X3, appx 90,000KMs. she was thinking of buying when it comes off lease at the end of March, 2017. That was before the dealer said she needed to replace the oil pump chain for $4,000. Now she (we) are re-thinking things and maybe getting a new one. I feel like the dealer is hosing me on the cost. I have a mechanic who can fix it for less but he’s never done the repair before.

      I don’t hear a noise coming from the engine that would suggest a problem but I am no expert.

      suggestions? Thanks

    Hey,
    After i’ve read about many problems on timing chain on N20 engine im thinking of replacing it, just in case. I dont have any noise, only thing ive noticed when changing engine oil was a few metal shavings in the old engine oil.
    Can you please tell me what parts should i order for changing timing chain?
    I found this link: http://bmwfans.info/parts-catalog/F30/Europe/328i-N20/browse/engine/timing_and_valve_train_timing_chain/
    but i dont know which ones to get.
    Another question, what parts have you changed on this N20 engine?
    Thank you!

    • You need part 1 through 6 and 10 and 16,,,,there are some other parts that are not in that list,,,you need valve cover gasket,lower pulley bolt and some other one I can’t think of at this time,,,,you also need a lot of special tools,,,,special timing tools and tools to lock the engine so it doesn’t turn,,,,you will have to tighten the front pulley bolt I believe 180 degrees,,,,,,I have replaced a lot of different parts on a n20,,,,from a turbo to camshaft to a complete engine.

    Hey Andreas,
    First off thanks so much for writing this blog and all the really useful info contained within. It’s really helpful and insightful for end users like me to see what goes on behind the scenes at the workshop.

    Anyway, just wanted your opinion…am looking at a used 2013 X3 x28 as we need the extra space due to a recent addition to the family 🙂

    But I have to say having done research on the N20 engine…it has been quite discouraging…timing chain issues which could lead to engine failure and now turbo issues….quite frightening stuff actually! So just wanted to know:

    1. Are the timing chain and turbo issues quite widespread on the N20 or just a few cases so it really depends on the luck of the draw…as is with every used car?

    2. If i get the 2013 N20 would it be expensive to replace the timing chain assembly with the redesigned version that came out in 2015?

    3. Should I just stay clear of the N20 and get an older 2011 X3 that has the N52 engine?

    Thanks much for your time.

    Hi there, it’s been interesting following your thread on the N20. I recently started noticing the dreaded whine coming from the front of my engine ’12 528i engine it has about 85K miles. BMW recommends replacing timing chain, guides & tensioners for $4.5K but made no mention of the Oil Pump (I assume it may be included but would verify). I have never worked on BMWs but am ASE master certified. I have some quick questions for you:
    Is the repair available as a kit including oil pump?
    You mention several special tools needed, I wouldn’t mind buying them but am hesitant to as I have yet to find a real how to, i would just be relying on my experience and knowledge to do the work, am I in over my head?.
    I also noticed the engine has a rough idle in gear that seems to smooth out after it reaches operating temp is this related or completely separate.
    I may move on from this one but since I can perform the repair it may be worth keeping, I like the car afterall.

    Hello Andreas,

    Have you seen the timing chain problem on a 428i (F32), yet? Perhaps the numbers aren’t there for the model but according to realOEM my N26 motor, built in 2013, has the same chain (# 11317584084).

    I bought the car a month ago, after 12 happy years in 330xi (e46), and there are only about 6 months left on the warranty. I buy a nice car, take care of it, learn to work on it and keep it. I was hoping for the same out of this F32. If I am keeping the car long-term, it sounds like eventually I will need the updated timing chain. Wouldn’t it be nice if it was on BMWs dime….

    I see, maybe the particular problem you have seen with the timing rail guide getting damaged is different to the timing chain problems which affected earlier BMW models (eg on the N47 engine, etc) although the end result of engine damage outcomes are similar in their seriousness and danger. I’m sure you would agree it is still important to have oil changes within the appropriate permitted levels to ensure the timing chain and other components are sufficiently lubricated, for example see:

    BMW says “proper oil changes” for a 2013 X3 N20 are about 15,000 miles, or about 24,000 km (it was changed to 10,000 miles for model year 2014). Such oil change intervals might be good until the warranty expires at 50,000 miles. But BMW probably thinks the “lifetime” of these cars ends at the warranty expiration.

    Hi Andreas!

    Thank you for all that you do! Your blog is a wonderful resource. I have a 2014 320i with the N20 engine. It’s under the CPO elite warranty until 2019, however, I do not put on that many miles per year, so at the mileages that people are reporting failures, I think I would be out of warranty.

    As a side note, a similar situation occurred to my parent’s Mercedes with a M272 engine. My mother’s extended warranty ran out based on time before the balance shaft sprocket issue reared its head to the tune of almost $5,000.

    I have seen reports online of the rails causing catastrophic damage without warning. Would you suggest as a preventive step I replace all of the require components (updated timing chain, oil pump chain, rails, etc.) before my warranty expires, or is this something that in your experience actually does give warning such as the high pitch noise from the front of the engine? The cost for components and eleven hours of labor surely is cheaper than sourcing and having installed a used engine.

      The shifting problem can be rectify by resetting the transmission adaptive values. I have had similar problems (feels like someone bump you from behind when shifting gears) on my E90 and now F30. Resetting the adaptive values is the only instant way to fix this. And no, the holding the gas and waiting thing people are posting on forums doesn’t work. Using a computer connected to the OBD-II port is the only way to do this.

      The problem MAY return if the computer learns “the wrong thing” again after driving for a while (like a few weeks), and you’ll need to reset it again. I’ve had to do it 3 times on my E90 to get it to stop. On my F30, I’ve reset it only once and it’s never done it since.

      Google around. You can easily do it yourself. You can even make the cable yourself if you’re handy, but eBay has them for like $25 if you want to just buy one.

    Hello Andreas

    First of all, thanks a lot for your effort to have shared all your knowledge and information :-). I have a question: On my 320i N20 (august 2012, 125000km -about 78Kmiles-) seems that I have (so far) no whining noticeable noise from the timing chain. However, it happened that since the last oil service the alarm “low oil pressure” has been raised 4 times during the last 1800 miles. It only (100% times) happens when engine is running very smooth for one hour or so (motorway, 6th gear, 60/70 mph, 2500 or 2600 rpm’s and always with the autospeed enabled). It only happens the alarm but not noticeable change in the engine noise. Then I stop car immediately, I stop engine, I re-start engine and everything is OK, and the situation doesn’t appear anymore for some weeks. Error codes 1C0102 and 1C2002 remain in the ECU. Do you believe this may be due to oil pump chain issue? Or the oil pump in itself? Or maybe from the pressure switch solenoid which manages the oil pump? The BMW dealer who made the oil service re-checked the oil/filter and they state that nothing to remark, even more they replaced by a second oil filter just in case. But i have the feeling that they are a bit lost. Have you experienced this issue with the N20’s? Do you think better Castrol oil than BMW oil? Do you believe may be related with the timing/oil pump chain issue ?Thanks in advance!

        Hi Andreas.
        Thanks for your answer. Yes, I also assumed that these codes (“engine oil pressure control” and “engine oil pump”) do not mean too much by themselves. They only reflect (and log) what the ECU “believes” that it happens according the information from the oil temp/pressure sensor.. After your answer, i keep the hope that the issue is not coming from oil pump/oil chain.. but we will see.. Next week the car will go to another dealer to perform a check .. My only concern is that unless they have a good data logger (the first dealer where i was stated that they didn’t have :-(, i am really not sure whethert they are going to see something relevant.. In my case I connected a scanner which logs the data from ECU but the issue did not appear at that moment (and in addition the scanner will get the same info that the ECU sees, so as you well mention, only an alternative method to obtain the real pressure -and log the result- should work. I saw a BMW special tool allocated in the oil filter housing which allows to do that (at least to measure oil pressure with an alternative instrument).. Let’s see.. By the way, with the scanner, i saw that there were two values readable for oil: “Oil pressure” (which is delivered in kgs/h -so i guess it’s really “oil flow”) and “oil pressure setpoint” (which is delivered in kPa unit). Do you know what is this second parameter? Is it the threshold or the actual value? .

        Well, in any case, i will share here the result of the investigation and the end of story in case it’s useful for other people who may face same issue.

    Hi, have you come across a waste gate type rattle from the turbo when starting from cold?
    Only occurs for around 30 secs and then stops. Seems like there is play in the turbo linkage but not sure if this is normal?
    Any help would be appreciated. Many thanks.

    Hello, I have a 2013 328i with 23k and am concerned with the potential timing chain issue since I”m out of warranty. I beleive I hear a whine but not sure if it’s related to the chain. Here is a pic from of the chain:

    Hi,

    Would you mind listening to my N20 engine to see if you can detect the timing chain issue? The engine revving comes at around second 20 on the recording.

    Thanks.

    He said he could not hear anything that sounded like timing chain wear. He also said that they do at least one of this fixes every week, that they make a lot of money on the repair and that he is very familiar with the issue.

    Do you know what mileage do Bmw these days test their engines to before mass production? They seem to have numerous faults and release a new model every 4 years or so just when the faults are coming out on the previous model only to release a host of faults on the new units.
    I would expect them to test their engines to 200000 miles with 95% making it there without significant expense and 98 or 99% making it to 100000 miles.
    Ive had failed valvetronic motor, Dme, injectors, coils, turbo rebuild ,vacuum pump issues, due to the oil overnight issue all at around 35000 miles. The dme is mounted on the hottest part of the engine behind the oil cooler for a laugh.
    I waiting for timing chain issues to occur but am proactively replacing the chain tensioner to hopefully stop it. Also worried about oil chain and oil pump issues as I know the oil pump is complex with variable displacement.

    • No I’m sorry I don’t know what the testing is on the engines,,,,they do seem to change everything every 4 years,,,,I think one of the problem is the customer want change,,,they want something new,,,something different,,,,something that the other car manufacture aren’t giving them,,,,and also BMW tries to stay ahead of everyone else and that means changes like it or not,,,,try and be on the cutting edge even if the fail,,,,at least they tried

    So a great car new under warranty with a replacement vehicle while your own receives a new engine but not so good outside warranty! Resale values will take a hammering as the years pass leading to higher monthly payments affecting new sales. I suppose bmw has their approved used program to delay this till year 4 or 5 so they are thinking ahead. Would hate to see their warranty costs. I still wonder how aftermarket warranty companies can warrant these cars at reasonable rates, or perhaps most make it to 80000 or 100000 miles out of warranty.

    So this is a video of my 2012 X1 with the N20. Just wondering if you hear the noise, or if I am being paranoid. It has about 62,000 km (38,525 miles) No warranty left.

        So would that be the top chain? Or would it be the oil pump chain module?
        I work at a Nissan dealership, what should they look for?

      • When you replace the timing chain with the guide rails you also replace the oil pump chain assemble at the same time,,,,ok they have to try and pin point the noise coming from the timing chain area,,,,there really isn’t much to see of find ,,,,there’s no real evidence to find,,,,it was just a bad design and a timing chain and guide rail that weren’t strong enough ,,,,the newer chain and guide rail are stronger.

    Also I had the oil filter housing replaced under under the recall, could that possible affect anything?

    Like

    • The only way the oil filter housing could affect anything if the old plastic oil filter housing was mixing oil and coolant,,,,but then it could have caused other problems like rod bearings going bad.
