Hi All
I have a 2012 with 7 speed s tronic. For months I thought I was having engine issues because the car would feel more lumpy and have less power sometimes but after checking everything I think it may be the transmission.
no faults what so ever and have also tried calibrating clutches etc.
symptoms are :
Car will jerk forward or back when in D or R from a standstill and when brake released. Can even see the Rpm drop and recover.
at about 75-80kmh the gears keep changing between 6 and 7 depending if I take my foot off the accelerator it will go to 7 and the moment I touch the pedal jumps to 6 and so on.....
In general the car feels like it’s towing a caravan and is really noticeable in slow rpms feels like it’s dragging and you can hear the engine working harder. The acceleration is affected too doesn’t go like it should when I floor it.
however it’s really intermittent. 2 out of 10 starts and the car is as smooth as a peach and the gears change perfectly.
Any ideas ?.
I thought mechatronic but I thought these things just fail and won’t be intermittent ?.
software or ecu ?.
any help would be great.
Thanks in Advance
