I was reading about this infamous M3 bearing issue on the roadfly board after me and a Caddy forums guy were getting at eachother about the reliability of the CTS and Cadillac products in general. In trying to tell me that BMWNA doesnt care about its customers he threw THIS thread at me. My car is a 2001 car with the standard 3.0 Litre engine. Do you guys know if any other motors were affected by all this mess?

Very interesting indeed.

The only engine with the bearing failure problem as a manufacturing error is with the S54 engine.
A bulletin came out once BMW was sure of the problem. This bulletin required the replacement of all the rod bearings and the oil pump.
Supposedly there was inadequate clearances in the pump and bearings, resulting in overheating of the rod bearings.
In addition to the repairs, the warranty for the engine components that require lubrication from the engine oil was extended-something to that effect. I don't remember the time frame or the exact components covered.

I've done probably 6 or so of these M3's myself. Most cases did show that the rod bearings were getting hot and worn prematurely, some did not.

All other engines are fine.
And I'll add that I'm not too fond of Cadillac. :P

BMW does care about it's customers. People have to understand that BMW did not yet know what the problem was with the M3 engine, and they HAD to investigate each engine on a case by case basis to study them, gather info, and make sure that it wasn't owner error-which is possible.
The author of that link said himself that BMW had replaced every engine. He found it insulting that BMW still required that each engine be inspected for cause of failure, or what was actually failed.
In any case, you have to rip the oil pan off to check these things, and it isn't a quick job.
BMW made right on this issue.

And if the Caddy lover believes that BMW doesn't care, then if true, the same can be said for every other auto maker out there.

Personally, I think BMW is one of the best as far as trying to please the customers, on the dealer side as well as corporate.
