Hi all, I've got a 2015 B8 2.0 TDI (163bhp) SE Technik. Not had the car long but it seems I can only briefly get warm air out of the passenger side vents on very low fan speed ( max speed 4 of 12 ) and the drivers side is always cold.
Initially I suspected an air lock or blocked matrix, ive tried to bleed the matrix inline with the Audi workshop manual. However after that not working or making no difference I discovered that apart from about 1/2 a pint of coolant on first start up, notuing is being fed to the matrix in the first place.
Anybody had this before ? I'm a mechanic myself so just thought I'd ask before I possibly go digging down wrong paths.
