Someone I know had a similar problem which was solved by re-entering the geographic coordinates.

I'll try reducing the pressure by 2-3 psi, as I did with my A4 B8 and see if that levels out the wear.

@RoyC Here's the label from my A5 I've noticed since running the pressures at 44 and 39 psi for the 245/40 R18 97V (I have 97Y fitted) over 6 months the tyres are wearing preferentially around the centre. I realise this will happen if over inflated, so I've checked pressure with a second and third gauge. Have you noticed this?

Yes, the P2002 fault has been resolved by a new EGR Valve and Cooler 🙂

Just to close this topic and avoid causing any confusion, the photo I uploaded in the first post is not the EGR valve. The EGR valve and cooler are located on the lower left rear side of the engine. The side of the valve can been seen looking through the gap indicated by the box in the photo. Foy anyone wanting to attempt this as a DIY, I can confirm it a 6+ hour job, and requires a great deal of patience With regards to the Cataclean, I used it back in April and drove to work (~35 miles) in 5th gear so the revs were at around 2000rpm There are several corners and roundabouts within 0.5 mile of leaving work before I get onto the A road. On the way home, I instantly noticed the car was much smoother accelerating so ran the Cataclean through another 35 miles. I took some measurements from the particulate filter before and after that can ben found here: Obviously it didn't fix the P2002 error because at the point at which the light comes on, removal is the only option. However in my view Cataclean is a superb product (thanks @Stevey Y). The car still feels very smooth when cold even before having the EGR Cooler and Valve replaced, so I have continued to use it at the frequency recommended. I've since mentioned it to others for their cars (other Audis, VW, BMW, Vauxhall) with mileage ranging from 60 - 240k and they have all reported the same outcome from the initial dose.

I bought the black lux1300gsm for my A5 from this seller - very happy with them after ~ 6 months/6k miles https://www.ebay.co.uk/itm/184701911568?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=FIklzonJR-u&sssrc=2349624&ssuid=BbKs5X6FTgi&var=692433863889&widget_ver=artemis&media=COPY

There has been some great collaboration and shared experiences here. It does appear this could be the result of loading and road conditions, however if the car was mine I'd still have it checked.

I'll be on the M25 in a couple of weeks, and will report back.

I don't know the answer to your SD card question. The factory NAV is !Removed!, so I don't use it.

Welcome to the forum. I personally wouldn't bother with the SD card, after having the same consideration when I bought my latest Audi. I plug my phone in ti the USB port and use the Android Auto (or Apple Play) which allows Google Maps. If you really want to use the factory Nav, buy the latest card your budget will allow.

These are great https://www.ebay.co.uk/itm/234554883890?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=i3N_Rb1OSNa&sssrc=2349624&ssuid=BbKs5X6FTgi&var=&widget_ver=artemis&media=COPY

Perhaps this could be a suspension issue like a little piece of spring has snapped off or a shock has suddenly failed? Either way, it needs inspecting because it's definitely not right.

MAGNET is right; if the tracking is out the tyres will wear unevenly, but at 4000 miles this could be difficult to identify. Most places off a free tracking check. Without driving the car, it could be either the tyre misshapen or needs balancing. Otherwise it's something more sinister. I personally wouldn't leave this too long, but rule out the basics first.

Does this occur at certain speeds as weighted imbalances will be more noticeable at a given frequency?

What do you mean "set to mid level rather than comfort"? You should inflate according to the recommended pressure for your loading condition as stated on the door plate. And yes, if the tracking is out your car can pull to a side. Get it checked.

Your original post asks "is this normal or should I be concerned" You get some solid advice, then come back quoting from the manual stating "usage is less than the manual says" Are you now happy or still consider there's an issue?

A guy I work with got the free MOT thing with an extended Warranty (in Cambridge I think) and they said he needed a tyre. They wanted something like £290 which was almost double what he could've got it for independently, but Audi wouldn't let him take the car on the grounds it was illegal to drive. And they refused to take it out of the workshop to accommodate him getting a mobile tyre fitter to change it.

I can empathise with finding a trustworthy garage. I don't have much experience with the B9 models having owned one for not much more than 5 months but my research suggests the catastrophic failure you're concerned about is very very unlikely. And if you did extend the warranty, how much of the cost would Audi actually cover? You might be better off keeping the money in your bank for the what if 🙂 Perhaps you could get Audi to do the servicing you mention, and leave it there. At least you have some go back if the unlikely happens. The cambelt is however a year overdue (it's whichever comes first of 5 years or 75k miles), so don't leave it much longer

In my opinion, once a car is outside the manufacturers standard warranty period, spending obscene amounts on keeping up dealership service history is a waste of money. The VAG specialist I take our cars to charge £130 for an oil and filter change, and £490 for the cambelt, water pump and auxiliary belt (A5 B9) which included a loan car for the duration. I only pay for whichever of 18,600 miles or 2 years is sooner because the VAG specialist updates the digital service record, so I'll typically be doing an oil change myself (or take them to a trusted garage) at the 9,300 miles and 1 year interval because of relative mileage/usage difference of both cars. When the cars reach 100k miles I generally care less about the digital record but still keep up with the proper service schedule because in my experience, anyone buying a car with >100k miles cares less about full dealership service history.

What style are they? I like these: https://www.ebay.co.uk/itm/175365832226?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=HaJLmSMMSjC&sssrc=2349624&ssuid=BbKs5X6FTgi&var=&widget_ver=artemis&media=COPY https://www.ebay.co.uk/itm/313981956630?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=_oUNxcpNQ9G&sssrc=2349624&ssuid=BbKs5X6FTgi&var=&widget_ver=artemis&media=COPY I think however black rims would look better on my car.

Ah yes. I'm running 245/40 R18 How do you find the 19s? I'm considering putting a set on mine 🤔

This is a very good point. I was surprised by the higher pressure going from A4 B8 to A5 B9 - definitely something to check. Are those pressures for extra load tyres and full occupancy?
