I don't usually have trouble getting comfortable in cars having rented many different cars over the years without issue and having owned several Audi's not experienced problems before. I am distinctly unimpressed with modern Audi vehicles and decided to buy a B7 RS4 to be a) comfortable and b) no annoying tech that doesn't work properly.

Awful situation to be in, I suggest you keep a diary of the changes you make to the seat position and what affect it has as it is easy to lose yourself with adjustments. For me, I ended up extending the foot rest with wooden blocks as this reduced the impact of the offset pedals a bit, intention was to closer align the footrest with the throttle pedal. The other change that helped me was extending the front of the seat squab out to support the back of the thigh. I am rather stunned at just how !Removed! awful the seats and pedal positions are, considering how long people have been designing cars, !Removed! it up this badly is unbelievable.

How do you stop the mirrors from randomly folding in as you are washing the car? I looked in the manual, worse than useless, not seeing anything on the web either. Just want to avoid getting my fingers crushed while washing the car. I have managed to get them to fold out with the drivers door open, shut the door so you can wash the car and they close again automatically a while later. I have no confidence they wont fold in when I am washing the mirrors and crush my hand or fingers. Any suggestions?

You will be lucky to find a single wingback seat let alone a cover. You would probably be better off talking to someone who retrims car interiors.

How worn are the tyres? This is normal behaviour and gets worse/more noticeable as the tyres wear.

Pricing up a 2021 S6 front discs and pads on ECP for Brembo parts is approx £400, not sure who makes OEM but £1600 is a lot.

Something worth trying is to extend the seat base front extension in addition to 2x18mm ply on the foot rest, just the ply wasn't comfortable but extending the front of the seat has made a big improvement in comfort. Still not perfect but a lot better.

I have a standard S6 Avant 21 plate, the one thing the base S6 does not have is the rear wheel steering which I believe the higher trim levels do have. Also not sure which seats you have experienced but I and others have found the driving position to be uncomfortablecat best with the sports seats, damn right painful at worst. Last thing to be aware of, the S6 is tiptronic not a dsg type gearbox. Everyone raves about the ZF8 but quite frankly IMO Audi have ballsed this up badly.

Look at the rating plate with the tyre pressures on (by catch on the drivers side door pillar), this will tell you the wheel/tyre combos that will fit as standard and doesn't knock the speedo out, etc. If none of these work then go off-piste with calculators and the malarkey. As for wheels, part numbers, etc - you need to find the parts diagrams online for your car as these will list part numbers for the OEM wheels, obs check with Audi the part number is correct before buying so you get the right wheels.

Regarding the auto close of the tailgate on the Avant, be careful what you wish for applies. It seems (and this is a guess) that my Avant had this enabled, the end result was having the tailgate close on me on several occasions, multiple times each occasion without any logic to it whilst loading up. Being the filling in a tailgate sandwich isn't particularly nice and it does hurt. The final straw was the damn thing closing unexpectedly in the dark as I was walking towards it, result was a concussion headache for a week. There are dim downwards facing lights (when the tailgate is open) but nothing that faces away that someone who is walking towards the rear of the car can see. My old b7 Avant had the rear facing lamp but the C8 does not! So many valuable features have been binned. At the end of day, users need to know whether doors and tailgates are open or closed and be confident they in the same position they expect them to be in. Regarding pressure washing the sunroof, I would expect it to be fine but go lightly on the seals and gaps. They are designed to stay sealed when driving at high speed but everything has a design limit, my other car has a sunroof and gets jetwashed regularly with the nozzle about 3 foot away and no issues.

I found a couple threads on the issue hence the question. https://www.ttforum.co.uk/threads/bag-in-coolant-tank-reservoir-bursting.2030154/ https://www.pistonheads.com/gassing/topic.asp?h=0&f=23&t=2056688 Would not put it past Audi to keep doing something daft like this and leave owners to carry the can. If my car has this I will get it removed if it has potential to cause issues, I do not need any more hassle from the S6 POS edition.

Read about this affecting VW's, etc so is this a potential problem for the C8 A6/S6 vehicles or has someone had a bit of common sense and designed this problem out?

That message is a complete pain in the preverbial, I had the same issue and ended up doing the same thing of logging out of the account, app, etc. Modern Audis are not user friendly, they (Audi) think they are being clever but they just annoy anyone with half a brain.

I was wondering this, good to have some else shed a bit more light on the issue. Could you provide a photo of your seats as I find identifying them a bit confusing. Happy to change the drivers seat if it solves this problem.

I have the supersport seats, you cannot lower the front independently, the rear can be raised relative to the front but this also raises the overall seat height. Can't believe Audi can get this so wrong.
