What else has been changed? Might be worth changing the spark plugs and ht leads to start off with as well as the injectors.

I suppose keeping it in efficiency mode for a duration of time would test whether it works by an increase in mpg. Dynamic would only see a quicker throttle response

Good call, other members have used them for retrofits and been happy with the results. If you want a comparison members have also used autologics.

Yep 4.2 parts will be expensive. Id recommend powerflow for aftermarket exhausts.

The price you've been quoted is fair. If car is completely dead from this then it could be the immobiliser in the cluster

I bet! I don't really have the patience lol

Get this back to the dealer asap as they should fix this foc within 30 days of purchase. As you say could be the cats, could it be egr or dpf? 🤔 When was gearbox oil last changed?

Darkside are well known and very experienced

For best results I'd say upgrade discs and pads. Depends how much you want to spend i guess.

What are the exact faults of the cluster?

Could it be the clutch and duel mass flywheel?

Fantastic work!

Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂

Definitely not a defect but not entirely sure what it is.

Please could you attach a picture?

Please keep us posted on how you get on. It'll be interesting to see what the remapper says.

I think the mirrors have either been painted or are the S6 versions. The wheels look like they're off a later A6 c7 in my opinion. Otherwise it looks stock.

Glad you got it off, they sure like to make it difficult!

You're welcome 😊

If you've bought it from a dealer within the last 30 days then they have the obligation to fix any issues FOC. You could always contact them and get them to give it a check over and a diagnostic check to see if any fault codes flag up

As Gareth says if you've bought it from a dealer within 30 days then they have the obligation to fix it FOC. At the very least the car will need a diagnostic check to see if any fault codes flag up. As it's an electrical issue it might be worth getting the battery checked as a failing battery can cause various electrical gremlins

No probs, sorry I can't give you more positive news.

Yea I'd say that's fairly normal. Is the engine temperature and oil temperature readings normal when driving?

Think all aidis have dmf now. Even my old a6 does. Here's someone with a similar issue but there's is an auto. There problems also started after a remap. I notice their torque is less than yours but that'll partly be due to there's being an auto. https://www.google.com/amp/s/www.audi-sport.net/xf/threads/audi-a6-40-tdi-c8-gearbox-vibration.431231/%3famp=1 I'd definitely recommend speaking to the tuning company. If it is the dmf you might need to upgrade it with an aftermarket one that's stronger, do a solid single flywheel conversion and uprated clutch. Here's an upgraded one for an example, but notice when the upgraded one can't handle over 475nm of torque whereas you're running over 500nm on the stick set up. https://clutchstop.co.uk/products/luk-dual-mass-flywheel-sachs-performance-clutch-kit-for-volkswagen-audi-seat-skoda-02q-6-speed-gearbox.html I've heard people talk about this company for upgraded clutches etc. But I don't see the A6 c8, but might be worth emailing them: https://clutch-specialists.co.uk/

Glad you're pleased with it, it's great to get positive feedback on modern Audi's. Especially as most people will only come onto a forum etc when they have a problem.
