I have a 2015 registered, Mark 3.5, 1.5 TDCI Titanium with about 56,000 on the clock. The car has been a delight to own and drive - I love it.
However about a couple of weeks ago I found myself in a slow moving traffic jam. With long waits between short, slow movements forward, whenever I came to a halt I put the gears into neutral and let the engine auto switch off. Every time I engaged 1st gear and gently let the clutch in the car emitted a (sometimes long) mournful moan (no other way to describe it!) - I seemed to feel a (very) slight vibration through the clutch pedal.
Once I got going the noise stopped and only came back v occasionally. Took the car to my dealer who could not get it to replicate the noise ... he said it sounded as though it was something to do with the clutch, but commented that the clutch felt fine to him. All he could say was that I should let him know if it happens again.
Today on approaching a roundabout I changed down from 3rd to 2nd and, again, on letting the clutch in I got the same mournful noise. Having got past the roundabout, with no traffic about, I came back down the gears and, again, got the noise. Doing it a third time, nothing.
Be most grateful if anyone could give me a clue as to what the problem might be?
