Not sure if anyone can help me but i think im developing a problem, my car is a Vectra 2.0 Turbo with 51300 on the clock.
I think my DMF is starting to fail as i have a rattle on idle and you can hear it tapping away around the gearstick area and also disappears upon pressing the clutch pedal, now im finding it is a little bit worse but not to bad.
What im getting now is from cold driving is fine as soon as it gets warmer i hear some knocking this is how it is hope it makes sense,
Press clutch select 1st gear drive away
At 2000rpm press clutch and go to select 2nd
As the revs are dropping i hear a faint knocking around the gearstick area but more towards the front of the car in the footwells
2nd, 3rd, 4th, 5th & 6th gears are fine and i dont hear it, im not getting and crunches from the box the gear changes are smooth and there is no knocking when accelerating or slowing down do you think this is DMF related i hope it is and not gearbox, i hope someone can help me.
