Anyone up for a timing chain DIY? I'm inclined get the necessary tools and replace all components before the engine fails. Looks like a time consuming project requiring fine attention to detail but there's plenty of space up front to get it done - unlike my previous car (B5 Passat) and it really doesn't seem all that difficult.

If you were closer, I'd throw in labor to help. It would be doing the community a great favor if you put a DIY together.
Maybe get a list of the OEM part numbers and let us know what special tools are needed and what all that hardware costs. Once we know how much time/labor it takes and what the hints, tips and tricks are, I'm sure some of us would tackle it ourselves, too. Quote:

I was at the dealer looking at a couple of different 328is yesterday. I looked at the chain in each of them and took a picture of the chain in one that was built in March 2015. It looked the same as the one built it July 2014.

It's a crap shoot which chain you have. The current #11318648732 is listed as being used starting 01/01/15, but the previous #11317584084 is listed as being used through 2/06/15.

Given the lack of real sample data, it is too difficult to determine any surety to this potential issue. I wouldn't lose sleep over this honestly. The N20 is used in many many BMW vehicles and barring any real hard data evidence on failures it, folks might be over-reacting abit.
I see more threads around this than the Takata airbags failures. |

As for 6s costing more, etc...with all the used/off lease cars, I think it's a moot point where the $ is concerned.....

This is a great thread. I am looking at buying a 2013 328i and reading lots about the chain guide issue which is worrying me and making me have 2nd thoughts. The car I’m looking at has 50k miles and serviced at 13k, 25k and 41k following the variable service intervals. I just wonder how much an issue this is and if I’m just hearing the horror stories and not all the delighted owners who’ve never had an issue. I need some balance!

Im down for DIY Seems like: > remove valve cover > all upper components in the way > lock cams at TDC, lock vanos then remove vanos > drop oil pan and remove oil pump chain + timing chain + guides > reinstall with new oil pan gasket + valve gasket Im in Oregon and my timing chain has already stretched as noted elsewhere on this forum: Basically it seems my timing chain has stretched on a portion of it, the rest of the timing chain is tight and certain times when the engine stops with the stretched portion resting up top i can see it and feel it below the oil filter cap. I was thinking about just doing this myself and recording it for a DIY vid. |

Hey mattwong92, I'm up in Seattle but wasn't planning on doing mine until 60k [@45k now] or whenever my car showed the slightest signs of failure. However, if you need a hand I wouldn't mind pitching in but it'd have to be after Christmas. Not sure if your car can last 'till then : (

Why are you guys looking to replace yourself when BMW just issued a "recall" of some sorts for this? At least that is my understanding, they are giving extended warranty or whatever for this issue.
Seems dealerships are jumping on the opportunity to replace and bill BMW now that it is official. Though maybe i read into it wrong? |

I don't believe BMW has issued any recall for this at all. BMW is replacing the ones under warranty when they acknowledge the issue dealer by dealer (from forum reads) but besides that when they self destruct, BMW refuses to replace the engine even if its under warranty to my knowledge. I took my car into my local dealership showing them the video of my stretched timing chain, and asked if I could replace the timing chain guide + oil pump chain + timing chain with the redesigned component from 2015 (I have an early Feb 2012 F30 328i that I got under factory warranty in 2015). They told me that timing chains were supposed to be like that and unless the engine was dead there was no way for me to prove that there was a timing chain issue.

I don't think I need to do it just yet as no other symptoms have come up (whining, loss in power, typical timing chain noises). However it sounds like we are at similar mileage'ish :P maybe i'll hold off until we both hit 60k. |

If I am correct, the timing chain tensioner is partially driven by oil pressure, so the chain will be "looser" when the engine is not running by design. What they are looking for is the noise. If you do not have the noise they will not look to replace it, but you should be covered to 7/70 now with the warranty extension. My car is now covered until September of 2020 so that gives me peace of mind to keep it for several years if I choose without worrying about it. But also keep in mind, failure rate is extremely low if you follow the many sources on the internet about the issue, and there has been some talk on the BMW technician site that affected vehicles tended to be cars that were going on extremely long oil change intervals. My 4 oil changes covered by BMW service were at 8,000 mile each (recommended was 10,000 miles) and now that I don't get free service I plan to do them myself every 5,000 miles. |
