Hello,
I am having a problem recently with my E320 CDI W210 Estate... occasionally, the ESP will engage (I think on rear left) for a brief moment (up to 1 second) when I am making a sharp-ish turn to the right. Very sometimes, also on a straight road.
Now - I have read a few theories:
1) Wheel alignment needs to be set
2) Tires are unevenly worn
3) Sensors (ABS) are faulty
4) Check suspension for play/worn elements
(1) has been done not so long ago (about a year) and I do not recall hitting any kerb or similar... (2) both tires are same age and spec - I can check but they were fitted only in May again (long winter here) and have never caused problems...
So I suspect (3) or (4) are most likely. Admittedly, I have been having something of a (muffled/gentle) thump in the rear right wheel when going over small, gentle bumps... normally I'd fix this right away but we just bought a W220 so cash was short to service the Estate and in normal flat-road driving the thump did not happen. Has been there for about 3 months now though. Could there be a connection?
Advice greatly appreciated I imagine that it would be wise to put it on STAR to check for any faults..? Would sensors leave faults stored?
