I have a Mercedes A class w168 of 2001 , and i have to lock it manually by pressing down all 3 door locks and when i step out i have to lock my driver door with the key , so the key unlocks all 4 doors but locks only my door (the driver door), it doesnt lock the boot .
The remote signal in key fob it doesnt work , i changed the batteries but still doesnt work.
There is a way to lock all car , is by closing all doors except one of back doors and pressing central lock , this way will lock all doors and the boot.
Its a bit complicated , the key it unlocks all doors manually , but locks just the driver door . Can you tell me how to repair this problem and the key signal problem , the key signal it doesnt work, i checked the fuse box but cant find anything .
Thank you very much
Also from a cold start the transmission will shift out of first but won't go to second or third the fluid has been changed and it's up to level the Boden cable is on and the trans fluid is clean
While driving the car and turn the corner the motor cuts off, it starts up again as soon as the car is in a straight forward position
Hello. I've purchased a '93 190E in great condition with the exception that it is running rough and seems to misfire on 2 cylinders. Once it's up to speed it seems fine, but not at idle. Could this be timing, some sort of sensor, valve or ??? Any thoughts as what I should look at?

Thanks for any help. Geof
At my wits end. Have replaced the obvious suspects, plugs, air filter, cat etc. and even the IACV to no avail. Want to fix problem, not just throw money at it and am currently about $60 from my waiver. Please help!!
how can i instal a compressor from c220 or other mercedes engines??? for more power?

Generally the car starts fine, drive 5 to 10 miles , press the accelerator and there is no response from the engine, Engine hesitates - will occasionally give a slight backfire ( coming from Air intake ? ). Press accelerator to the floor and the situation seems to work itself out after a mile or two.
Bought the car 6 monts ago with 51,000 miles - car is in like new condition.
