Let's not be disingenuous. Your point was that BMW can't seem to get it right with rod bearings and doesn't care, and you said that they didn't do anything for the S54 failures. My point is the brief issue with S54 bearings had nothing to do with BMW's bearing design. It was a problem with their supplier, which makes your assertion that the BMW spec is an issue spanning at least two generations false. In addition, BMW issued a recall for the affected S54's and gave extended warranties to a range of cars, so they did in fact do something for the S54. Finally, the last several years of S54 production have perfectly acceptable bearings, which is verification that BMW's design was never the problem. |
Don?t even get me going on his assertion that all high performance cars have to come with some sort of technical compromise....bearings shouldn?t even be a variable in the design, at this point in engineering and manufacturing you just assess the requirements and find the appropriate bearing.
I would have cut bmw some slack if they pushed the envelope with variable intake runner length or something and F?ed up. But F?ing up bearings is just embarrassing. |
Complaining about it on a forum isn't going to stop the wear nor save the S65 from it's seemingly innevitable doom. Considering the total number of failures are a fraction of total produced, it's unfair to call this an epidemic of sorts. Forums provide a biased view of the issue because only those affected with complete failure and or those who preventatively replace the bearings report their findings here.
My M3 has been the most reliable car I've ever owned. It's the only car to never leave me stranded. This includes my two previous BMW's, my 13' 128i and my 12' 135i. Both of those cars had multiple issues over my ownership experience.
