A fault has developed on my wife's BMW whereby when she is crawling to a halt (e.g. at a busy roundabout) or manoeuvring at slow speed the car shudders from what appears to be engine vibration. When the revs rise it goes away and it is intermittent in nature. The sensation is closest to when a novice driver rabbits a manual on its clutch.
The car is an auto and has just been serviced by the main dealer, it has done 79k miles. I have also noticed that the mpg has dropped off by a about 2 mpg recently.
I would greatly appreciate it if anyone could offer any advice, the dealer plugged it into their computer and merely said "yes it is running a little roughly but we will need it in overnight to find out the cause"!?!
Many thanks, Adam
