Hello everyone. My problem is when I turn the steering wheel completely to the left or right. 2 weeks after driving off the used car dealer (Autonation), a ABS / EPS inoperative light came on. They fixed the issue under dealership warranty (now expired), but the vehicle had the same noise ever since I purchased the vehicle. Just wondering if the problem could be related or, as a friend suggested to me, is this is a common issue with the M-Class? Most importantly how could I troubleshoot the issue myself, and hopefully resolve it?
