My 2002 M3 has had a continuous problem with load moaning when sharp turns are made at slow speeds. There was a service bulletin concerning this problem, and the fluid was replaced with a different kind. This helped for a while but the problem returned. The differential was then replaced under warantee and was silent for about 5000 miles when the same symptoms came back. Again the fluid was replaced per the service bulletin. This time it had no effect, so the district service rep was contacted and drove the car. At this poing he determined that BMW would NOT again replace the differential.
What are my recourses at this point? I know from experience that contacting BMWNA is fruitless - they tell you to work it out with your dealer. I have the feeling that BMW does not want to put any more money into this car under warantee - I only have 3 more months.
Someone with experience please offer constructive advise - if it means legal action, then please specify against whom. Or is the BMWCCA omnbudsman program usefull in these kinds of disputes?
Thanks, Bob
