I just recently bought a 2007 Ford Mondeo 1.8 TDCI 6 Speed Manual and it has picked up a very annoying vibration the car has done 158000 miles (used to be a private taxi) the symptoms i'm having are intermittent difficulty putting the car into 1st gear, intermittent lumpy idle and the whole car shakes when holding the engine at around 1500rpm but then smooths out at around 2000rpm it also shakes when i'm travelling at any speed apart from when i apply the brakes and it seems to stop vibrating, the engine also makes a hollow rattle when pulling away in 1st, also when i shut the engine off the whole car shudders, i originally thought it could be either the engine mounts or the dual mass flywheel but the flywheel was only replaced within the last 10000 miles or so. Just thought i would get other peoples opinions first before carrying out any maintenance, Hope someone can shed some light on this very annoying problem.
