So update on this one now the car has been to the garage:

1) White smoke: Did your test, no smoke so I assume it was nothing abnormal and is instead me being a bit paranoid. 

2) I got them to check out the wheel issue. The challenge was tire feathering (abnormal wear) which was causing the road noise on front right. They've moved it onto the back to try and reduce the noise, but a new tire will be needed at some point. My MOT is in May so I plan to get new ones before then; as you say, they're reaching the end of their life soon in any case. 

Thanks for your help on this!

Hi both - thanks for your help; really appreciate it.

1) Will wait for a dry day to do the coolant test you reference. Is the logic if the smoke gets worse; then its likely a coolant leak?

2) On the wheel - it steers true, a little pull to the left but nothing I'd view as abnormal and no vibration or friction when steering. I'm thinking it's likely tire wear too given the mileage; did the 20p test though and seems they've got a bit of life in them yet but will get get them checked out.

I'll come back as I get the testing done - cheers again

Hello whoever you are.

Before anyone can comment, could you please take a little time and fill in your profile, and let us know whether you have a petrol or diesel engined car. 
At the moment, you hold the record for the most incomplete profile! 
Many thanks,

Gareth. 

I like to live in the shadows. It’s a petrol - thanks for your help!

Hi all - hoping someone on here may be able to offer some advice. I’m having some issues with my 2018 Audi A3 (18k miles, automatic). 
 

1) It seems like my car has a disproportionate amount of white smoke coming out the exhaust. I don’t think it’s condensation, yet I can’t smell a sweet coolant smell from the exhaust. I notice it when I’m idling, even after the car has been running for a while. I’ve also noticed white stains inside the engine compartment (see attached)

2) I think I have a bad wheel bearing. At around 40mph I get this whooping noise off the front right wheel, it gets faster the more I accelerate. My question with this is I’m surprised a wheel bearing has gone after 18k miles, so wondering if it could be that? 
 

thanks for your help!

I have a 2018 Audi A3 with 18k miles on it. I’m finding I have a couple of issues:

1) I seem to have excessive white smoke coming out my exhaust, even once the car is warmed up, in idle when stopped it seems like there is more smoke coming out than normal. I checked in the engine bay and there was a white residue, but when cleaned up it didn’t reappear. I thought it was a coolant leak, but how can I confirm? Coolant levels haven’t dropped down either. 

2) at around 40mph my front right wheel start whooping which changes with speed. I think the wheel bearing is damaged, but is this normal at 18k miles?

thanks in advanced!
