Hi,
New to the forum, so apologies for any new member mistakes
I have a w211 e220 estate 54 plate auto that I've had about 6 months. My first Merc. It has 120k on the clock.
I seem to have a gearbox or engine rev issue when the car starts from cold. When I first drive off from a cold start the car doesn't seem to have much power and it struggles to pull smoothly and is reluctant to change up a gear for the first few seconds. After 30 seconds or so of driving my Rev counter then begins to 'wave' up and down and I can't hold the rpm.
This stays like this for around the first 5 minutes of driving and is worst when at around 30mph or 1200rpm-1500rpm.
Also it occasionally seems to moves up a gear when there is apparently no need eg I'll be at 35mph and applying a gentle continuous throttle and it will seemingly go up a gear causing the car to make a low rumble/shuddering and the Rev to drop to under 1000, I have to 'kick down' to bring it back down a gear.
After 10 minutes or so of driving or when re-started from warm it doesn't have these problems. As I tend to only do shortish journeys though, this is really aggravating.
I did take it to local garage and they put a star diagnostic on it but couldn't find a corresponding error code. Any help/ideas would be much appreciated!!
