Ok so to wrap up this subject-the RS went into Audi yesterday for the coolant pipe issue. Audi reports back that its surface corrosion and so it's not a negative issue at this time. They also confirmed what others have said that extended comprehensive Audi warranty does NOT cover corrosion. So that's a self funding job if it rears its ugly head and I don't fancy paying Audi labour rates when a specialist such as MRC can do the same (if not better) at a cheaper rate.
Everything else checked out and whilst she's in there it was time for an oil service and brake fluid change. £385.00 for the oil and £59.00 for the brake fluid in case anyone is wondering.
Looks like I dodged the coolant pipe issue although am sure at some stage in the future surface corrosion will become deep corrosion.
I'm now seriously going to have a think about the extended warranty. I'm going to put this on a separate thread on here and the general section as then I can get a better idea of whether to renew or find a suitable alternative.
As a replacement car while the RS was in they have given me a new Q7.... I'm not a fan of them to be honest and Q7 drivers can be a bunch of tools I've noticed. Anyhow-apart from the fact that they have totally screwed up the design (Audi is on point with their design and I love the look of most of the new ones especially the C7 shape-the Q7 just looks like it's made of Lego!), the current tech has been really impressing me especially the dash nav:
Very Gucci and shows how far technology has advanced since the C6.
But it's still a wallowing pudding of a car though.....looking forward to getting the RS back.
