Before watching the video I'd have said look at loose heat shields, engine mounts or other loose components in the engine bay. But that sounds worse. Could it be the lower pulley coming loose?
I second cliffs advice. To add though, you could take it to a specific tuning company like darkside developments, again it'll be expensive but sure they'll find the problems.
If bought within 30 days get it back to them asap as they have to fix it for you as you're entitled to a full refund up to 30 days. If it's over 30 days then speak to Audi if you're luck is on your side and have some manufacturers warranty left.
An auto electrican would be able to confirm if it was aftermarket. Alternatively if you remove one of the sensors then this should have an Audi part number on it if genuine
Known faults on VAG cars. Could be the float is stuck. Which needs the rank has to be drained and assessed. I'd recommend a diagnostic check as a fault code will flag up for a stuck float etc.
Yep you're right, the blade has to be cut and electronics coded. Audi will want £300 at least. An independent company Neill charge around £150. shop around as prices vary 👍
You've done a great amount of diagnostic work 👍 might be worth considering the switch (I'm assuming nits electronic parking brake) or have an auto electrican to take a look at the wiring.
Very nice. Nope 6 speed manual. It certainly is lol. But we have had it from new so it's sentimental.
Not going to lie not need some cosmetics but whilst she's still doing major road trips I said I wouldn't do the bodywork as guaranteed id have Ito done up then someone would crash into it on a roadtrip. I've got it set up on Instagram and Twitter if you're on there. It has a Facebook page too but I'm still setting that up. I'm off to Germany in less than two weeks to take it back to where it was built 🙂
