I'd definitely recommend getting a proper diagnosis. As loosing coolant isn't good. What colour smoke is coming out of the exhaust, because if it's not leaking then it could be a failing head gasket. I'd definitely recommend thoroughly checking the coolant system though, it could even be the expansion tank cap seal.

Sorry to hear of your situation, is it worth considering a garage further afield? I appreciate it's a massive inconvenience but I know this is something id consider.

Yep you can do a sales post. Please put a price and pictures. Thank you.

If within 30 days of purchase then take it back to the dealer for them to check and fix as it will be FOC. Also within 30 days period of you're not happy you can get a full refund. I'd definitely recommend a diagnostic check.

Glad you're pleased with your c8 🙂 might be able to get the phonebox retrofitted. Autologics have been used by members with positive results

You're welcome 🙂 I've been looking myself when the time comes.

I'd recommend a diagnostic check. If the servicing is all present then I'd consider a sensor issue.

Might be worth asking for pictures from the seller so you can compare it to yours. Also ask for the part number. You might be able to make one good one from both.

Have you considered the injectors or glow plugs? On my A6 c5 I've had to change the glow plugs. But I think I'll have to change the injectors at some point.

When I had this on a ford escort many moons ago it was the stalk unit that had to be replaced. This is also a common issue on french cars. So definitely worth a check. Especially as you've changed everything else.

I'd recommend check your light seals and boot seals first off.

I'd definitely recommend a diagnostic check now as you've done what you can.

I believe Sach do upgraded clutches for stage 1 and 2.

It's not the most economical as the q3 is a big car. What ever the official mpg figures are then take 10 off them.

No probs. If you've bought it within 30 days the garage have to put it right.

No probs at all 🙂

It technically is an MOT failure if you remove dpf. Even though I can understand why youre thinking of it.

How are you getting on with this?

Key things is service history. Is there proof of the Cambelt being changed, has the gearbox oil been changed? If quattro are all tyres same tread on each axle as uneven wear can damage the quattro system. Have a look at some buyers guides on YouTube. My friend has a 3.2 TT and engine has been mechanically fine (2007 model)

Part numbers will change. You could speak to Audi to see what the current part number is. Or alternatively have a look on eBay and ask a few sellers.

Could definitely be driveshafts or engine mounts.

It could be the glow plugs or wiring to the glow plugs. How old are they? Is the car struggling to start. You'd be surprised how little glow plugs the car can run on for start up. For example I've just had mine chsbge on my A6 c5 a d only 3 out of the 6 were working.

I'd be getting the battery checked as first port of call. But you could also get an auto electrican to check the alternator.

Actuator should throw up a code in theory. I'm guessing all boost hoses have been checked. The last thing is then the turbo.

I agree not is very strange.
