I agree with Cliff, get this back to the dealer you bought it from asap. I wonder if this is the reason the previous owner traded it in....

Could be a timing belt issue. What's the engine code/bhp? I ask because the older version of the engine such as AYM etc had a different head whereby if the cambelt snapped/jumped it wouldn't wreck the head/valves etc. Where as the later engines with 180bhp engine codes bsu or similar has a revised head with roller cams whereby if the cambelt snapped/jumped the pistons could smash into the valves and wreck the head.

These issues are usually linked to a failing battery but as you've had it changed I wonder if it's a wiring issue from the battery to the dash? Or an issue with the instrument cluster.

It might be worth taking it back from where it was fitted. They may have missed something.

Have you done a diagnostic check to see if any fault codes flag up? Could be an issue with the high pressure fuel pump.

Just the thermostat I believe.

Can you not gain access by removing the front wheels and wheel arch liner?

You might find the wiring harness won't be compatible. Also the new one might need coding.

Looks nice 👍

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

Regarding water in the boot, check the boot seal and lift seals to see if they're letting water in. You'll need a special convertible roof cleaner.

Sounds like it should have rear parking sensors.

Is there proof of gearbox oil changes and Quattro system services.

Looks nice

Glad it's been sorted. Worn suspension arm bushes are common on audis.

That's annoying, you'd have thought there would have been some good will.

You've done good diagnosis so far. I'd recommend it go to an auto electrician for further diagnosis.

Please keep us posted on how you get on

Glad you got sorted

They're not cheap that's fore sure. Just to throw an option out there have you thought of an upgraded exhaust too? Powerflow are reasonable or used to be.

It might scrape. Have you researched the ferry you're going on. Or speak to ferry provider regarding ramp angles

Please keep us posted on how you get on with the A5. Get it back to the dealer for the warning lights to be sorted.

I'd recommend getting it changed now as it's 6 years old.

I'd recommend a diagnostic check to see if any fault codes flag up as it might not be the regulator
