Hi,
Need opinions please. I have a 2017 MT GT coupe.
Since brand new, I have had a drive-line wobble or shake right at the clutch take up point when letting the clutch out - low revs (less than 1000 rpm). This is when when you have to slip the clutch slightly at the take up point, eg manouvering in tight spaces, creeping along in stop go traffic etc. Forward & reverse.
You can fell it through the clutch - like it could be high spots on the driven plate - but that's a guess. There is no noise, just a "wobble" that can be felt through the whole car - passengers notice it - my wife, not mechanical said - "..you need to get that fixed". I would have called it clutch shudder. It is only when you have to be holding that extra half second at the take-up point (you can go longer if you need to hold at the slip point, but usually you are out to the t/u point, get motion, in with the clutch again etc.) The clutch is fine when you are in/out with normal gear changes. Normal take-offs are fine usually - because you are through the take-up point quickly and we know these cars are hard to stall.
1st dealer said - "...its normal they all do it. I just checked two on the lot."
2nd dealer - found no fault although at that time, I did not know the exact conditions that allow you to emulate it every time.
The 3rd dealer who could feel it from the passenger seat (even though I was only on a very slight up incline - it is worse the more load there is) said, "...yes they all have that, its the dual mass flywheel...".
I have put off modding till I get sorted - feedback please. I have had several manual cars, last one a 996 Carrera - that had D/M flywheel - no shudder what-so-ever.
Also - when new gearbox - slight whine - now a gravelly noise - getting louder, at low revs (just off idle) 1st & 2nd under load.
Cheers
