? Driveshaft wear? Toyota Auris T180 76k miles

That's certainly an odd one David, and not something I've heard of before... if it were on an old rear-wheel drive car I'd say the propshaft had come out of balance or one of the prop couplings was defective, but seeing as it's FWD it can't be any of these. I'm wondering whether there could possibly be a problem with an engine mount breaking up allowing the engine to move slightly? Depressing the clutch might be enough to put things back into alignment. Or could it be a fault with the car's dual mass flywheel being out of balance? It seems as if many modern cars seem to need a new DMF when the clutch is replaced as they can wear and have too much play - could possibly be this? Do let us know how you get on as this could be of assistance to other CarGuru users. Cheers, Bob.

Many thanks Bob - I'll share with my local garage too. Thanks for the comment about the DMF - hadn't thought of that. Regards, Dave.
