In Feb of last year i bought a lovely looking e211CDI and drove it for a month before going away. on my return 2 months later a series of problems started which have just about P-----d me off. On my return the car stuck in first gear and would not change. i took it to MBTech in Warrington who informed me of a list of problems that required sorting so biting the bullet I told them to go ahead and at the end recieved a bill for 2900 pounds but thought that at least I now had a properly sorted car which would last me many a year. Part of the work done was a gearbox oil and filter change. I had barely done 300 miles when a juddering indicated torque converter problems. This was sorted out with a new converter for a bill of 700pounds. I have now spent 3600 pounds on a 3000 pound car. As you are all probably aware part of the job is a gearbox oil and filter change despite the fact that it had only been changed a few hundred miles ago. I have only done a few hundred miles since the converter was changed and started to get gear change problems resulting in the car not changing at all. The panel indicator said it was a speed sensor problem. I then took the car to a local garage who said that all indications where that it was the speed sensor and the would need to drop the gearbox sump and have a look. I recieved a phone call to say that when they looked at the gearbox it was dry of oil and this would probably be the cause of the problems. Because of the cost involved they just renewed the oil, replaced the seals and handed it back. it now will not change gear. The advice I need from you guys with more knowledge than myself is where do i stand now. I have written to The Converter Shop as they where the last to work on the car but as from now have recieved no response. I have a feeling that all concerned are just going to say " It was all right when it left here mate". I am left in a position that if dont get the job done with unseen costs I am left with a car with only scrap value after spending 4000 pounds to put right.. If I give a garage the go ahead and it costs me a couple of grand then I am left in a position that i will have spent 6-7 thousand on the same car. I fel that somewhere along the road someone should take responsibility but not sure what I can do which is where I would appreciate the advice. After owning Mercs for 30 yrs without problems you can understand why i am p----d off.
