Hey All
hope you can help. I have bought a used E250 CDI about 3 months ago (2014 MY) from a Mercedes main dealer and have the Mercedes approved used car warranty. Just before i purchased it it had had a B service including the tranny oil change. After driving for about 2 months i noticed the gearbox acting weird. when starting off it was holding 1st and 2nd longer than it should, sometimes up to 4500RPM before changing (with a light foot). I brought the car to the dealer and they were able to recreate the issue once or twice. They carried out a relearn cycle on the gearbox and told me to expect some rough changes for the first 500km or so.
1000km later the car is acting weirder. the issue with it holding revs in 1st and second is no longer as pronounced but now i am experiencing lumpy (thumping) downshifts from 5-4 and sometimes 4-3 , sometimes the car will lurch forward as a result if i am coming to a stop in traffic. this does not happen all of the time and can be quite intermittent. Its in the garage now and they are giving the usual "no errors in the gearbox, we will keep it overnight and drive it" line. i have seen sporadic posts in US and UK forums about his but no consistency in the answers. Is this something i should push with the dealer? Its certainly not comfortable to drive anymore as i am expecting and bracing for the thumps. i get the feeling they will try send it back to me with a "no fault found, works on my computer" diagnosis
