Scubayorks

Hi Gareth, thanks for your great reply, I bought the car from a main dealer (non-audi) and have 1yrs warranty with the car so it’s been investigated to the point where it was booked in to Audi and they diagnosed that the heating issue on the drivers side was down to the flap motor but also saw a code for heater matrix and suggested this may need changing. From what I can see and feel the carpets are bone dry. At the time they weren’t aware of the excessive coolant use so weren’t testing for that as since I topped it up it had been fine for 2 weeks then just yesterday I noticed it had shot down. i will give an update as soon as I have it though as the non-main dealer are liaising with Audi and claiming back under extended warranty and it looks like it’s going to be the defrost motor flap and heater matrix that get replaced, they quoted £1300 for the work did Audi so glad I’m not paying!

Hi, this is my first post and to confirm I have the same issue. Were the above fixed with the heater matrix? Car has been pressure tested and no issues then all of a sudden it uses a bunch of coolant, I too have a lukewarm drivers side compared to passenger side. It’s refreshing to find someone else who has had the same problem
