Hi, I bought my 2015 228xi Sport Line three years ago. It now has 65000 miles on it and has overall been very reliable. My CPO warranty is expiring (due to time/not miles) next month.

I'm going to get the oil changed at the dealer this coming Saturday and was wondering if there are any tips before my CPO warranty closes out?

What I will have them look at so far:
* Timing Chain: a while back I received a warranty extension on the Timing Chain to 7 years/70000 miles. I'm going to ask them to double check that area.
* Comfort Access is Slow: the lock/unlocking feature seems to be slowing down.
* Other? let me know if there are any other general trouble areas for the 2 series I should have them look at.

I don't have the "maintenance warranty", just the standard mfg. defects etc warranty.

Thanks for the feedback!

The slowness of Comfort Access may be because of a low fob battery. These batteries are very easy to change. Just follow the instructions in the manual.

The timing chain guide issue is real enough that I would consider turning it in/selling and upgrading. It is a roll of the dice if you elect to keep it. Tough decision possibly?

Have you been using the auto stop/start function?

I haven't used the auto-stop/start function that much (less than 5% of the days I've had the car). Does its' use contribute to the chain guide issue?

Is the Timing Chain Guide an expensive repair (relative to other high BMW repairs)

I don't think its been proven the start/stop increases the chances of timing chain problem.

If the guide fails, it totally destroys the engine. And yes thats very expensive.

To get the parts replaced before failure is also expensive.

I haven't owned my 228 long enough to weigh in definitively but I can provide some perspective:

I briefly owned a 2007 B7 S4 which also had timing chain guides that liked to disintegrate over many years. You usually got some form of warning before it happened but not much, and if it failed spectacularly you were out an entire engine.

The quotes I got on that timing service was $7-8,000

Going into a 228 I knew that timing guides were also a problem so I called around and asked, and did my own research on the internet here.

Quotes on the 228 have ranged from $1,500-2000. Not cheap but much more reasonable. I know a few people have managed to get it goodwilled from BMW after their extended warranty ran out as well. Might be good to buy your service advisor dinner.

This is why I sold my 328i.

If I didn't have the money to upgrade, however, I would have certainly replaced the timing chain before the warranty expired.

I agree with everything above. Not proven, just a theory? However , the problem is real and expensive. Buyer beware. I am not a fan of internet hysteria and propagating fear over imminent engine implosion, but I have it on good advice that the N20 engine problems are not worth messing with, as the miles pile up, so does the risk.

I'm going to put this right here:

I had my door actuators replaced because they were slow to open. I would tell them as a CPO repair.
