Help needed for friend with £5k audi repair bill - coventry

[nicknameless]

Hi Everyone,

Can you possibly help with some approximate costs and even recommendations for a local specialist?

I have a friend who owns a 2012 A3 Sport 2.0 TDI. He recently had an mot at audi where he was advised about a 'slight chatter' from the gearbox casing, but was not told that it needed attention. A couple of weeks later this turned into a 'loud grinding and knocking sound'. Car still driveable and just been inspected by audi who are advising 'major damage' and bill for just over £5k for new box etc.

This sounds majorly wrong on so many levels, not least the quote! Car is in the Coventry / Kenilworth area - can anyone recommend a good gearbox / vdub specialist in this vicinity who can be trusted to diagnose and quote fairly? I had an 8L S3 a few years back and used to use Midland VW in Cannock back then who were great but if there's anything nearer to Cov / Kenilworth / Birmingham that would be great.

Not sure on diagnosis or realistic prices if this did need a new / recon box?

Many thanks all in advance,

N

It's a 6 speed box. Any recommendations locally or idea of realistic price?
