Thanks Redred,
My A4 has got ridiculously low mileage, just turned 10k but I'm wondering if my relative has a terrible driving style, riding the clutch a lot.
It's just had an annual service at the Audi dealership before I bought it and nothing was mentioned about the clutch.
It's not slipping and I'll monitor it, I'm assuming there's no way to adjust the bite point.
If I find out more I'll post back.
Good luck.
