There are lots of debate whether the chain or the guides fail first. It is really hard to know for sure but I believe both could happen. Most have reported a whinning noise before failure but some claims it happened without warning. I believe the ones that happened without warning are the ones where the guide broke first. This is what I would like to avoid. I would still monitor if the chain makes this whinning noise. |

I am currently looking at buying a 2013 X3 28i but everything that I have been reading about the timing chain issues is kind of throwing me for a loop. Is it a 100% certainty that I am going to lose my timing chain at some point? Can I just replace the guide and have a peace of mind? Do I only need to replace the tensioner? Any help from those more experienced would be greatly appreciated.

The people on this forum, myself included are only a small fraction of the people in the world driving these cars that are affected. If I was to re-purchase though I would purchase one with the updated parts just for piece of mind.. My 2013 has a whiny oil pump but once warm it goes away and drives like a dream @ 102k miles just be sure to change your oil every 6-6500 miles and disable start stop. Both of those tips seem to go a long way.

Model: 2013 328i N26
Build: Munich 01/2013 Mileage: 77k miles Timing Chain Status: No problems Oil Changes: Every 6k since 45k Stop/Start Status: Coded off at 50k Additional Details: Bootmod3 at 60k, I have always been on top of maintenance because that's all my car has needed, every oil change has been with Liqui Moly products and have used CeraTec every 30k, just poured in my second bottle after my previous oil change. I got this car used with 45k, and it still runs like new. Oil changes done from 45k to 74k I used Liqui Moly Leichtlauf High Tech 5W 40 with a bottle of Mos2 Anti-Friction additive. I started doing research on the new Molygen oils and gave it a shot at 74k, it made the engine is a lot quieter at idle. So I do believe it has the proper mix of Additives and this is my new oil as I am not going to buy the Mos2 additive anymore and will be using just the Molygen 5W 40. Service records only indicate warranty work for the steering wheel horn, and when I take my oil cap off I see the orange timing chain guides, so it's all original. |

Model: 2014 328xi N26
Mileage: 33k miles Timing Chain Status: No problems, but replaced under CPO warranty Oil Changes: Every 7.5k since 9k (bought at 9k) Stop/Start Status: Turned off since 10k Took my car in for an oil change and brake fluid flush. CPO expires in 02/2020 so I asked the dealer to check a bunch of stuff including the timing chain. They reported back saying timing chain was good and no problems. I insisted that I wanted to replace it since the motor won't be covered under the extended limited warranty in case something were to happen. They were kind enough to accept and replaced it under CPO warranty. I had the car advertised on the forum briefly and it really bugged me that nobody was even willing to consider it because of the potential timing chain issue. I eventually decided to keep the car and pushed the dealer to replace it. Took some effort but worth it since it gives me peace of mind.

Maybe should clarify that the timing chain may not be the only thing to go wrong.
In my case it was the guides breaking into the oil pan.

If you have a N26, your turbo is covered under the SULEV warranty. Got mine replaced under that.
