Hello Gideon,
Looks great.
Answers:- If you don’t want to pay Audi dealer price for a handbook, then search on EBay, or get seller to provide you with one - as should be the case.
AdBlue:- Handbook will confirm yes or no, but I would guess yes.
Spare wheel:- If the car isn’t equipped with a spare wheel, it won’t have a jack, but it should have a smallish compressor and a pressurised container of tyre ‘gue’ which you release into the flat tyre before re-inflating with the compressor. This is to be treated only as an emergency get-you-home procedure, and renders the tyre unusable.
The seller should have ensured the car had a compressor and gue, so it’s a trip back there if not.
Want to convert to the more reliable ‘space saver’, jack and wheel brace su stem -? Again search EBay, but you are likely to need the foam insert as well to store the Jack etc.
Speaker in well ? You will obviously need to work out how to relocate that.
Perhaps you could keep us updated Gideon.
Kind regards,
Gareth.
p.s. I can’t open your images.
