I've done 57K miles since new in our 3 litre PVC with Comfortmatic transmission. So far we've had no problems but on this trip something hasn't been right.
I noticed first that immediately after starting, the engine was running a bit hesitant. Hard to describe but it was if it was telling me to put my foot down so it could clear its throat. This was something new which I haven't experienced before.
Then things changed and on a few occasions recently after starting the engine and attempting to drive off it lurches forward and stalls the engine. It's like a classic learner driver kangaroo start. This has happened both when starting from cold and when hot. For example, after a long drive we stopped, I switched off the engine then spotted a better place to park. On restarting the engine it did the kangaroo hop and stalled.
Once we are going drive take up is perfect. If we stop at a junction it pulls away perfectly. Gear changes when moving are fine. There are no rattles.
I won't list my thoughts as I don't want to influence opinions other than to say my first thoughts were a failing dual mass flywheel but the symptoms don't show when pulling away at junctions, only after starting the engine. This morning I ran the engine on fast idle for a short period after starting and it didn't do the kangaroo impression but it was still hesitant as we moved over to the service point on the aire.
Thoughts and suggestions most welcome.
