UPDATE:
Dear Gareth, firstly many thanks for your input. It has been SUPER helpful and I genuinely really appreciate it.
Took it to an indy today just to get it on a ramp and see (no cost). To be honest, it actually doesn't look bad at all, the hole is tiny and doesn't look like the tyres or anything has actually been damaged.
Moving forward, I think everyone agrees if I take it to main dealer as planned, they will want to change the whole part. Ideally I would still like to get the small hole patched up however the indy said to me he would agree but doesn't know who would actually do that? I don't do any diy stuff or have access because of career and work hours unfortunately.
As for the metal that was taken off (jacking point), I'm not sure who or how would repair that either, but upon closer inspection again you really can't see a huge difference and doesn't look like (Hopefully) that it will cause any problems.
Any suggestions how to proceed from here and who may be able to do this work. Audi want to charge £100 before actually carrying out any work, absolute joke
