Tyre Wear and Warranty Work!

Hi, went for a service and MOT - Left with a potential £900 bill.

I have two queries though. One regarding changing tyres for which advice would be helpful and the other being regarding a potential warranty issue.

Bought the vehicle in Jan and at the time all tires had 7mm tread except front left which had 5mm for some reason. Fast forward 6.5k miles later at this service, the front left is on 2.5mm apparently and the front right is 4mm with the rest being not far behind. Pretty shocked. >65% Motorway miles (albeit at speed).
I am aware to change tyres in 2's unfortunately and I like the Michelin's on the vehicle even though they get terrible durability! I have attached a picture showing the wear from the health check and I think it resembles that I am over inflating the tyres when you look at the pattern of wear? Not sure how this happened because I check it regularly and fill air in accordance with door sticker!? Any opinions? Or recommendations on tyres?
If I therefore under inflated the tyres to even the wear out could I potentially keep it longer? Rather change them after Jan 2021 and allow me to cover at least maybe another 3-5k on them. Pretty bad wear I must say.


Other problem is my passenger door is sticking when opening from inside. Dealer confirmed fault. Said they need the car for an hour to change some sort of cable? Said as vehicle is under warranty parts will be covered but labour is £190!?!?!?!? To fix a stiff door!? Do I have to pay for labour if under warranty?
When asked if they could tell me the problem so I could take to another dealer instead they said they would have to diagnose it themselves first so extra cost. Basically means either live with the stuck door or pay the £190. I don't mind paying for good quality but I just feel it's a bit extortionate. Vehicle has full dealer service history and everything.

Not overly happy.

Many thanks for all the responses from everyone. Happy to have lots of opinions.

1. The vehicle is under the Approved Used Warranty which I didn't think much of. But the service manager said himself that they will claim from it to do the work providing I pay £190. I don't mind paying, but £190 just because the door is a bit stiff seems not great! I messaged Audi UK (because I'm working all day currently as far as I can see) and they want to speak to the guy who dealt with me? Not sure if this sounds good ? But they also said I don't have a warranty somehow despite these documents and told me to have a good day ahaha

2. As for the tyres. Vehicle isn't a Quattro so I presume 2 tyres changed should suffice? A6 is Quattro and did all 4 on them.

The wear is even from what I can tell. When I bought it the front left was on 5mm and the rest on 7mm. So it seems to be wearing evenly

Current plan is to just buy new Michelin tyres around January (cover at least 3-4k more and they should be around FL: 1.6mm and FR: less than 3mm probably). My only concern is I do mostly travel on the motorway across the country and on the Scottish roads there is a lot of aquaplaning so as much as I don't want to start giving in and paying for all the advisories, I also don't want an accident

2 questions though:
- I have attached a ticker of the tyre pressures (my size is 245/40 R18 93Y). I normally pump 39psi front and 36psi rear. This seems to be causing overinflation type wear though. Any opinions? Am I looking at the correct pressures

- Lastly, if bought 2 new tyres they replace the fronts. I am aware of the theory however to place new tyres on the rear for better handling incase? But if I went to Audi I presume they would just put the new ones on the front and send me on my way? Is one method preferable? Because I also realise that the front will wear quicker so if I put new tyres on front they will be gone in half the time!


Many thanks. Any opinions on this?

Quick update.
Contacted Audi UK who must've been quite firm with the dealer as the next morning I receive a very legally written email explaining the whole situation.

Basically, they have dropped the initial diagnostic charge from £190 to £134. They say this will not be charged at all if the suspected 'Bowden Cable' fault (passenger door doesn't open properly from inside) is covered by warranty. A bit more pleased with this but still think £134 to open a door is a bit more than I was hoping.

I have since asked the dealer to inform me before I bring the car back if the Bowden cable would be covered under warranty? Don't want to spend the £134 diagnostic charge to be told it's not covered. Does this sound right to you guys, would they tell me this info?

Thanks

First, really sorry to hear your woes.

Is this report from a Main Stealer? I assume it passed the MOT? If so ignore the red warning, I got that from a VW dealer on our Golf. They report amber at 4mm and red at 3mm. >1.6mm is legal, 4mm is ok on an AUC. So they sell cars with advisories? NO absolutely not, it's to scare vulnerable customers into parting with stupid amounts of hard earned for mid range tyres (sorry that's a rant!!).

It's not unusual for front tyres to wear on the edges due to the effects of power steering, not the other way round. Over inflation or wrong tyre/wheel size I assume. Too wide a tyre and/or too narrow a rim. I run recommended pressures and the first lot wore evenly and did 30.000 75% motorway miles. Do you always use the same pressure gauge? If so is it accurate? Having said that Inner wear on the rears? Spacers?

As for warranty work, is it a main dealer warranty? If so, go and park it outside their delivery bay and demand they fix it. If not, is labour excluded in the small-print? If it is I'd prob next talk to trading standards as a warranty that only supplies parts is pointless because even if you fitted the parts yourself the repair would void the warranty.

Sorry for the late reply, this just got me curious now actually.

Same tyres all round. Genuine AO marked Michelins 245/40 R18 93Y all round. Pressures checked frequently from fuel station air machines (done on first trip to ensure cold temperatures as much as possible).

Passed the MOT fine. In fact they did the MOT free of charge and yes main 'stealer' ahaha.

Also as mentioned, it is the approved warranty and they say £134 will be payable if it's not covered. Can they not tell me this beforehand though as I don't want to pay £134 to be told it's not covered!
