Absolutely 100% disillusioned with MB UK.
The saga of my 09/2007 W204 C220 CDI Sport continues.
Gearbox software problems from new.
Updated software numerous times.
New torque converter at 33,000 miles (symptoms from 20,000 onwards), and software on both the engine and gearbox "updated'. I am positive that this had a negative effect on both the economy and performance.
Torque converter symptoms returned recently at 50,000 miles, and reported to MB at 60,000 mile service.
MB took it in for examination and could find no fault. When I took the technician out in the car, he agreed 100% that the problem was the torque converter.
They have had the car for the last 3 weeks, and in that time they have:-
1. Tried numerous "re-adaptions" on the torque converter
2. Fiddled about with the software
3. Changed the ATM fluid completely
4. Changed the ATM fluid (for a "different type" of ATM fluid) again
5. Fitted a new prop shaft (this one left both me and the technician baffled)
6. Finally fitted second replacement (third from new) new torque converter
The symptoms (vibration and humming) have now disappeared, but I am sure the car has also been de-tuned (again). I am going to take the car for a dyno test tomorrow to see what power it is producing as it is definitely not pulling as strongly as it did pre the above.
To top all this, when the car was returned to me after 3 weeks, there was a scratch and scuff on the front bumper which I noticed only when I got home.
MB will not accept responsibility for the bodywork damage, but are willing to have their repairer (non-MB, but MB "approved") make good out of "goodwill". I am insisting that an MB repairer does the repair, but MB dealer says he won't pay. Does anyone know the legal position regarding nomination of repairer please? Can't believe MB would refuse my nomination of authorised and franchised MB bodyshop!!!
