Hello - First time ive posted on here, so will need all the help I can get!
I have a C220 CDI Sports Coupé. It seems to have 'late' gear changes.(high reving even if I take the foot off the power). Have recently started to have problems with changes too - ie. gets stuck in about 2nd or 3rd. I have to switch off the ignition and restart, then its ok for a while, or it might do it straight away. Tho Only seems to do this on longer runs - 20miles or more. Nipping to the shops, she seems fine. No fault or error comes up on the computor screen on the dashboard.
Is this a serious fault?? or just electronic or ATF change??! PLEASE ADVISE!
(I have bought a multiplexer and carsoft 7.4 if this will help me???!)
