►Part Two of Two: There is one major Achilles heel with the BMW N20 and BMW N26 engines, the timing chain. BMW N20 timing chain issues are known to cause potentially catastrophic effects if not maintained properly. Because there isn’t much information out there regarding how to actually replace the timing chain and guides, we put together this start-to-finish DIY video to show you how it’s done.
Part one of our BMW N20 timing chain replacement DIY, linked below, focuses primarily on the diagnosis, removal, and disassembly of the job. Part two outlines the installation, re-assembly, and start-up procedures.
BMW N20 Timing Chain Extended Warranty: Recently, BMW released an extended warranty that covers the timing chain and drive chain for the oil pump. A limited warranty for defects in materials or workmanship has been extended to 7 years/70,000 miles as determined from the original in-service date. This coverage is subject to the same vehicle eligibility requirements, limitations, and exclusions that apply to the BMW New Vehicle Limited Warranty for passenger cars and light trucks.
BMW N20 Timing Chain Replacement Costs: If you were to take a comparable vehicle to your local BMW dealership and have the job quoted/installed, depending on parts/availability/location, we estimate a roughly $5,000 estimate for parts and labor.

Do I need a scan tool for this job ?
I couldn’t have done this job in my 13 N26Xdrive…. In driveway without the help of this video and the kit I purchased from FCP Euro. Thanks a million times over.
Just replaced my timing chain, car runs but is throwing codes. P054B P052B. Intake and exhaust camshaft timing retarded. I used the tools as instructed in the video. Any help or ideas?
Each time you do a job it goes faster. There should be shops that just do timing chain guide replacements and nothing else.
Thank you so much follow every step and did my own thank you for taking the time to show us all
I made the chain change in my N20 F10 528i . Thanks FCPEuro for putting out these videos and providing all parts in a single kit. The procedure is very much alike in my F10 without X-Drive as shown on your series 3. I did it in my garage with couple of stands and a HF engine bar to lift the engine to make clearance to remove the oil pan. With 73K miles, the original chain and tensioner were still in good condition, nothing broken, nothing loose, nothing weak. But, the potential for a future (catastrophic) failure was present. I hope this new chain kit does not show any new flaws in the future as miles pile up on it.
Great video very helpful I appreciate the information doing my first tomorrow. I'm just curious that front main seal is a ptfe seal the instructions say to leave them dry. Do you suggest using lube ? Also you call them cam adjusters are they not just reloctor wheels? I only ask cause I want to do this job well but I feel like I'm nagging not my intention
2012 328i timing chain just broke. 70,000 miles.
Thinking of putting in a motor from a 2015 328i…built after 3/2015.
Anyone know if a 2015 motor will work in a 2012?
*Update
Called BMW. They checked VIN.
Said car was opted in. They will cover 75% of new motor installed( since milage was over 70,000miles). Not bad considering its almost 10 yrs old.
I have question.the vanos bolt tighten after adjuster fixing or.before adjuster fixing?
