Hi Gareth, Agreed and well said👍

Hi Tom Have you tried PAGID, my Audi specialist will be fitting new discs to my S7 and says PAGID are made to OEM Spec and usually way cheaper than Brembo. It maybe worth giving them a try?

Hi Martin, Very smart car, look after it👍

👍👍

My point exactly, unless going into storage or taken out of use.

Steve, I have done similar with my S7 and relied on guidance from easily accessible websites that ask you for your original set up together with your proposed set up, and then show you the impact that the change will have on clearance, speed variants, etc. etc. I found these sites invaluable and have now completed my upgrade and all is fine. Give sites a try like: www.willtheyfit.com or www.thewheelcalculator.com

Alex, If your car is in regular use and is not modified or highly tuned, I think using E10 is probably fine and would make little or no difference to the cars performance. However, if your car goes into storage or is off the road during the winter months, then using E5 is a better bet. It contains less ethanol than E10 and ethanol creates condensation which over time can damage fuel lines and potentially cause corrosion in the fuel tank. Hope this is useful.

Mark, Not sure when you intend buying your replacement tyres, but Asda Tyres (sounds daft I know, but I've bought tyres from them before and been pleased) seem to have some good deals currently. They have all brands and will deliver to your door for you to arrange fitment (my choice) or will arrange fitment for you at your local tyre premises. Worth checking their prices

Hi Gareth, These days it seems that everyone is getting less for their money, I guess it includes tyres as well!! Regards Chris

Your always safe with Michelins, the only reason I steered away from them was because of potential tyre noise. Check out their db. rating as not all versions of Michelins are the same. Grip, handling and wear will be good I'm sure.

Mark, For my S7 I've recently bought 275/35/20 Bridgestone's as they were rated at 69db compared to the Pirelli's at 73db. I know that doesn't look like a lot of difference, but there is a lot of rubber on the road and when fitted to 4 wheels, believe me it does make a difference. Grip and handling in both wet and dry seems fine.

Unfortunately, I think your probably right.

Hi Cliff & Gareth, Many thanks for your messages. I fully appreciate how difficult it must be to try and discourage the non-response from members who have been given, what's supposed to be, helpful assistance! Anyway, as you say lets hope it will improve one day Regards to both Chris.

Hi Simon, Following the message I sent you above re your hot starting issue, I was wondering if my reply had been any help to you?

Hi Simon, S8 V10, very tasty! Interestingly I have an S7 with the V8 4.0 Twin Turbo unit fitted, but I too have a hot start issue. If the car has been used and brought up to normal operating temperature and then shut-off for anything more than around 5/10 minutes max, it doesn't like starting cleanly. It does always start, but not as it should and I dont feel fires on all 8 cylinders immediately. It doesn't take many seconds, maybe 2 or 3, to settle itself down, but I don't feel its right. I have discussed the issue with my local independent Audi service centre and they initially thought all signals point towards the crankshaft position sensor. This I asked them to replace with a new genuine Audi part, but much to their surprise and my disappointment it didnt fix the problem, but looking on the positive side and embarking on what is now an elimination process (but a costly one) that particular sensor can be forgotten about. The service centre are now feeling that the fuel pumps are possibly making the mixture too rich when the engine is being started hot and whilst the car will start from cold perfectly, even after standing for a week or two, the service centre are thinking that the mixture is too rich when starting from hot. This theory is also supported by the fact that if i open the throttle, not fully, but a good half, when starting from hot, the engine fires up more quickly than no throttle at all which can take 3 or 4 attempts. In both scenarios the engine does not start cleanly, just more quickly with the throttle open. Currently I am at the stage of using the car as is because everything else is great, and when I've done about 500 miles since the service centre cleared any stored codes etc, I've been asked to return the car to see if any new codes have been stored. At the moment the service centre who are Audi specialists and very familiar with their various engines, feel that it could be that the fuel pumps that could be giving trouble on hot starts. Does any of this sound familiar to you and can you relate to any of the issues that I'm experiencing?
