Hi do you have / could you share the part numbers please. Been trying to buy these from my local Audi dealer and they won’t sell them to me 🙄🙄🙄 - quoting WTLP requirements. Tried to explain that they are options on a new car but no joy.Welcome to the site. I am sure that over the next few days you will have answers to your questions. I have a 2020 model and the biggest problem was setting up the MMI due to the number of options. I would recommend purchasing a second SIM as the Audi data plan is very expensive. I would also recommend using myAudi on your mobile as it gives a remote status of the vehicle. This is FOC.
If you set the wing mirror adjuster on the drivers door to left then when you engage reverse the left mirror will drop. You can adjust this when stationary with the ignition on by setting the adjuster to left, engaging reverse then adjusting the mirror to the desired position.
The Q3 should come with a user manual by default. Mine was in a wallet in the glove compartment. Somewhere on this site there is a link to a pdf of the manual. If you have any problems finding this, I have a copy.
Quite a few owners have had a rear view camera and/or front sensors retro-fitted. This can be done by the dealer (expensive) or an indie using the kit from Kulfatec which is reasonably priced.
What you have in the boot is correct. You can change this to a space saver spare, toolkit and jack but you do need a boot polystyrene insert to retain everything. I had this done on mine for £250+VAT.
If you have any further questions then please yell.
if I have the part numbers might will try to source from different dealers
any help would be much appreciated
