I feel an intermittent grinding sensation through the accelerator pedal and occasionally the clutch pedal when cruising.
Passengers can't hear it so I'm assuming I'm imagining that I can hear it.
What could it be?
For example, it often happens when cruising at 30 miles an hour in 3rd or 4th and foot resting gently or feathering accelerator to keep at speed. However, it can happen on the motor way cruising at 60-70 as well. The main thing, it happens only when cruising not breaking or accelerating/pulling away. Depressing the clutch doesn't stop it.
I've just had new clutch and DMF but this problem was from before - I'm noticing it more now, I think. I've also just had full electrics diagnostics which show up no major problems (cruise control occasionally turns off when I press SET- (minus) but I don't really care about that too much). No warning lights showing. 2 mechanics have done short test drives and think it's a smooth driving car and can't feel the grinding sensation.
I have Ford Mondeo Zetec (2010) diesel, 140bhp, 1997, 35,000miles ish.
Suggestions please, folks!
Thanks for any help. Anska.
