ok I’m getting a lot of questions about the N20 timing chain noise and replacement,,,,here are 2 short audio clips,,,,you can here a high pitched whine in both videos. one video is at 3000rpms,,,,and the other is reving the engine up and down,,,I sent both videos to BMW to get approval on the timing chain repairs.
Here I removed the valve cover and inspected from the top of the engine for any visual problem,,,I don’t know if you can see it in the picture,,,,on top of the chain you can see shiney marks,,,that is an indication the chain is rubbing on something,,,,those marks are not normally there.
Here the old timing chain and guide reins,,,the guide rails were broken.
Here you can see where they broke,,,,the two rails would normally be snapped together.
Here the old oil pump timing chain module,,,,this comes complete as you see it,,,,did not find anything wrong with this,,,but BMW wants us to replace it at the same time as the timing chain.
Here are the new timing chain guides and rails,,,the new ones are white in color and made of a better plastic we hope,,,,lol.
This is the new oil pump timing chain module complete just bolt in,,,,this job is not one of the best to do,,,,this was on a X3 so I had to deal with the front axles and front differential,,,,,this job only pays about 9.5 hours,,,so you pretty much have one day to complete the job to make any money.,,,I hope this helps some of you guys about the timing chain issues.

Thank you for all of the great info. I recently purchased a 5/2012 X3 XDrive 28i 2013 and my daughter drove it to school. Now I’m trying to figure out if the guides and chain have already been replaced by her pictures. Carfax is the only history I have and it does not specifically state that the job was done. Would it be common for warranty work to be done and not doc umented? Do the pictures look correct, and does the chain look like it has stress to you? She does not hear the sound during engine revs. Thanks, Dave (Nervous Dad)

Dave, I’ve got the same exact car and I am also concerned about this issue. I don’t know if mine has the new guards installed, seems like the previous owner had that issue and somehow fixed it. I took it to BMW service today and they told me it was diagnosed needing a new engine last year! but it is still running, so I am guessing they did repair it somehow but I don’t have those records.

Just received a Class-Action Notice against BMW regarding the below defects which could lead to sudden engine failure, model years 2012-2015 (my car 320i 2013): 1. Failed timing chain module 2. Failed oil pump drive chain module 3. And or failed engine due to the failure of 1 & 2 above According to the Notice, I MAY BE entitled to reimbursement for past expenses provided under the settlement. If BMW knew of the defects, why wasn’t a re-call issued? Now I have to spend my $ dollars and hope I will be reimbursed once the judge makes a final decision. If the defects aren’t fixed I’m putting my life in “Jeopardy” by continuing to drive this defected vehicle. This is so Totally Unacceptable! And to top it off, there was excessive smoke coming from my exhaust after sitting overnight. I was told the turbo oil feed line had to be replaced. Did some research online and found many BMW owners with this same problem, this too should have been a re-call issue. Does the Oil Feed line have anything to do with the failed oil pump drive defect?

Sheila,
I found this post after searching a little after my dealer/service department told me my 2013 BMW 328i cannot be fixed without a large motor inspection. It shut off on me while driving and would never crank back. It turned over just fine, but would never start. After being in the shop for over a week, that’s the call I got today. This is a huge cost and the service manager said it may not be even worth fixing. The car is immaculate but does have 170k miles on it. I was first told it was probably the STP oil filter used in the last oil change at Firestone since it wasn’t OEM. That seemed quite weird to me. Then this. Im at a loss frankly. I sure hope this turns out to be good for everyone.

They complimented my 2015 328ix on the mileage (56k) miles as well as the condition and paint job( still Factory) . This interaction has restored my faith in BMW even given the fact this is my 1st BMW bought from a dodge dealership lol.

No none of these crazy ideas would help,,,it’s not a oil issue,,not a idle issue,,,crazy glue won’t help,,,we don’t have this issue on other BMW engines,,,when the N20 and N26 came out it was just a weak design.

Ensure you disable/turn off the stop-start function, & change oil 5000-6000miles. Best things you can do to prolong the life of your chain.

That’s not going to prolong the life of the timing chain,,,bad design,,,timing chain and rail not made strong enough

I was wondering what you think about my 328i N26 timing chain. I don’t have much lateral wiggle. It’s very minimal. I was checking my timing chain when my engine was sitting for a while so it wasn’t super hot but wasn’t cold. I was wondering if the picture in my google drive link look like my timing chain guide has been replaced as it isn’t as dark an many other non replaced timing chains. How does my chain look for a car with 99,000 miles. I don’t know if it’s been changed so that why I was asking if it looks like it has. https://drive.google.com/drive/folders/10IPDLmxlvaUQLAmst-UtRWQBd-XZX9kh

I own a 2016 BMW 328i F34 with the N26 Engine… the car build date is 2015-09-08… the car has 148,000 km on it… I have been told that this car does not have Timing Chain Issues, but I looked at the chain guide (through the oil filler) and it is the dark-brown color… I do not hear any whining noises or clicking noises in the engine… I was wondering if you could give me some advice on whether or not to have the timing chain looked at/replaced… thank you…

You could have a timing chain test and see if it passes the test

We were driving our 2014 X3 carefully waiting for timing chain recall when it thre a “Drivetrain Malfunction “ code. Dealer says turbo (wastegate) failed. To save money, we’re having turbo replaced when timing chain recall work is done, but I’ve two questions for you: A local mechanic says he’s been seeing a LOT of BMW turbo failures in his shop. Any chance there’ll be a recall on turbos? Also, looks like Mitsubishi (PN 11657642469) is OEM, and I can buy it for $1300 new online. Dealer wants $3200 for turbo! Am I getting ripped off??

I don’t think you will see a turbo recall,,,dealer prices are alway higher then anyone else.

You can also consider a rebuilt, it is a lot cheaper than new.

Also if the problem is with the wastegate actuator, you can just change the actuator and not the entire turbo.

Correct you don’t have to replace the whole turbo if the issue is just the wastegate

Hi there. Bought a 2012 320i approved used in 2019. Car was running when I arrived to test drive, and I think I now understand why. I bought it with 50k on the clock and I have only covered 12k in 3 years. I’ve kept to BMW recommended service intervals and have used main dealer. First problem was about a year in: oil pump kit replaced following a whine, which I assumed issue to be timing chain. I was assured it wasn’t.
Car began to overheat in October 2020 so I had it towed, needed water pump replaced and solved potential coolant leaks. Car began overheating again (only orange warning this time) and is currently in the dealership awaiting ANOTHER water pump only 8 months later after it failed the first time. They’re investigating timing chain failure & turbo damage (although I’ve had to be pushy about the chain as the dealer seems to do as little as they can get away with.) I believe and pray this will all be covered under my extended warranty which runs out in 4 months.
Beyond hard cold starts, intermittently limited power, and whining under acceleration, I’ve noticed a knock from under RHD driver side which follows throttle lift-off ~3000rpm. I’ll attach a video of (presumably) chain whine and the other issue. Do you have any advice? I’m so concerned and anxious that the dealer will try and do as little as possible! Thanks for your time.

Hi again. Sorry I didn’t follow up last time. I ended up getting a new water pump and a turbo replacement – presumably the water pump for the overheating (they cited an internal water pump failure), and the turbo because of the noise I was hearing. Alas, I’ve noticed the noise again and I’m left wondering what it is; surely not turbo if I’ve just got a replacement? Will be in contact with BMW again, but the ownership experience is getting pretty tiring.
Here’s a link to the video:

I don’t know if we will get the correct answer from BMW,,,,it could be a couple of things chain not strong enough,,plastic rail weak and get hot and fall apart,,,timing chain stretch,,,no body knows,,,,and it doesn’t happen on all N20

I believe the issue was figured out to be ethanol in US engines making the plastic brittle. From my understanding, which may or may not be correct, EU engines that run on non-ethanol gasoline do NOT experience these issues, even with the old timing chain guides. I believe the reformulated plastic in the ‘new’ parts which BMW introduced in ~2015? specifically addresses these issues.

I’m curious how the Ethanol would contact any part of the timing chain or guide.

@wannalearn14 Oil contamination via the cylinder walls/piston rings. The same way oil gets black from exhaust soot. Again, i’m not 100% sure on this theory, but i’d like to explore it in discussion.

Hi, I am looking to purchase a used 2013 BMW X3 xDrive28i in the US with 79k miles on it and 2 previous owners. The carfax is clean and it says there have been timely oil changes. I went for a test drive and loved the car. After coming home, I researched and found out about the timing chain issue. I had opened up the engine hood and looked for any unsettling noise but could not find any whining sound as mentioned in this post. I did hear a different sound which they told me were the turbines making the noise. I am now worried if I should purchase the vehicle. I have asked them to check and tell me if the timing chain was replaced previously. Are there any other components I should ask them to check particularly or replace entirely before I make a purchase? Also, I am buying it from a dealership and not a certified BMW showroom but the dealership is a reliable one. They are ready to provide a service warranty but we are yet to discuss the details. Should I ask them to include the engine repair/replacement in the warranty? Also, I am thinking of keeping this car for 4-5 years at least. Do you think if I get the parts replaced and maintain it properly (which I dutifully will), this will last me for the next 3-4 years at least without any major problems?
