It uses the new design and should be free of the timing chain problem. Doesn't mean that it won't have other problems though

So do we know which part is the culprit?

Will Realoem show which parts my car specifically has if I enter my Vin? Or does it show what bmw currently uses. I'm trying to determine if I have the newest parts.

I have a 2012 328i with 57,000 miles.
I just got word today that BMW is going to replace the engine. That is a relief to me for sure. I was told it could be 2 weeks before its done. I've been waiting ~40 days so far. It looks like BMW is going to do the right thing and stand behind their product.

Good to know! Glad BMW stepped up to the plate. Just wondering did you service your car at the dealership therefore having all service records intact?

Luckily I had gotten a copy of the receipt for the one oil change that was not done at the dealership and that was enough to prove it had been changed on schedule. I was told BMW probably would not have done anything had I not had it.

What's your oil change intervals? 10k or 15k? Do you use the auto stop start function as well?

I have seen some N20 with 100k+miles without any problems, but some have timing chain issues in about 40kmiles.

Trying to find the pattern here.

Are you CPO or out of warranty?


Also....I guess this means its a good idea to have BMW do all the oil changes.... that sucks as id rather do them myself.

You can always perform your own oil change in b/t the BMW intervals. Based on my CBS my next schedule change is Nov. 2018!

Just dropped my car off at the dealership for an oil change and had a chance to talk to the shop foreman who just got back from a big conference with some of the top tech people at BMW. It appears that BMW did modify the original chain in someway before the part number eventually changed. The data he had showed there has not been a car produced after 05/2013 with a failure with the vast majority of them being 2012 production or earlier. He seemed pretty confident the issue has been solved and anyone after mid 2013 should not be overly concerned if they keep up with oil changes. I was able to glimpse some graphs of the worldwide raw data that seemed to support his claims.

Really? Build year after 05/2013 will be free of the timing chain issue? That sounds much relief.

I can only speak to the data I was shown. When I pick up my car I can try to reconfirm the date. He had worldwide failure data which completely flatlined after early 2013 production. Any "failure" after this date was a misdiagnosis - coming straight from the head of engineering according to the foreman. They changed the original design of the timing chain to minimize friction that was occurring in one specific place, and the data seems to support it worked. Ultimately they did a complete redesign with new part numbers which we are aware of, but minor changes did occur prior to the part number change, which was new info to me. They also shortened the oil change intervals as there was data supporting people running past 15k were having a disproportionately higher failure rate. New cars actually are going to have a prompt which you will have to acknowledge before being able to drive the car past the change interval, and Munich will be counting.

Take this info as you may, but after speaking with him I feel much better about my early 2014 build.

Good info, thanks.

Just checked and my 2013 N26 was built 03/2013..

At this point, im going to change oil every 5-7K on my own and get BMW to do the oil changes when the computer tells me. Every time i bring it in ill ask them to check the chain and listen for any noises and hopefully im good.

I have a CPO warranty until July 2020 so a bit before I need to really worry. Would be great if something went SLIGHTLY wrong before that and I just got the newer parts. I LOVE my car and would really like to keep it long, long term. I have a family and two young girls so I dont feel like wasting money on buying and selling cars every few years. No engine mods either, only thing I might do is save up for an AWE exhaust but I dont see how that could cause me a headache if my TC ever went bad.

Like I said take the information as you will. I just figured it was of value to share here. My tech did say that any "failure" after a specific date in 2013 was misdiagnosed, implying that there were repairs done as if the problem was chain related but was later determined that wasn't the specific issue with that vehicle. His observations on the matter where that the oil pump itself was a bigger issue as he has seen multiple of those fail yet not one chain failure in his shop, Elmhurst BMW, great people btw for anyone in Chicago tired of Perillo. Perhaps this specific 2014 had an oil pump issue and BMW told them to just replace everything while they were in there.

Is that a common issue on N20 engine regarding to the oil pump/chain?

It seems they redesign that part as well after 2015..
