E240 W211 advise please - Merc Newbie
So I recently bought a Mercedes E240 2003 model and totally love it. The dealer done some work on it for me before it was passed by COR (like control arms, brakes, lights etc). I have tinted the windows and had it Glazed as well, not to mention a valet. I now have to change the power steering pump and its making a huge noise. I have already ordered one and a mech form Mercedes will install it for me.
What I have noticed is a vibration at 2000rpm and sometimes jerking. This happens when drive slow. Also it feels like a delay when putting my foot flat on the accelerator. My guess is the transmission mounting needs to be changed. Does anyone have any ideas?
The clock is on 270 000km.
I had a similar problem, and the dealer diagnostic showed fault codes relating to the catalytic converters which the were happy to charge me $3k for.
I had my personal tech run a diagnostic test, and it presented the same fault codes, and confirmed the car was misfiring. First we serviced the car, then did some other diagnostics which revealed the cause of the fault codes to be the oxygen sensors.
The faulty sensors resulted in a rich mixture, which in turn fouled up the plugs and resulted in the misfiring. Got new sensors installed today, and she's driving like a dream. This could be your problem as well, but you will need to do the diagnostic to check.
Hope this helps.
