Hi, just joined today, on my third Audi A4, got a 1.8t sport quattro avant, have a couple of problems I could do with some advice on, the climate won't hold a steady temperature, had a diagnostic done and it said temperature flap postioning sensor faulty, where is this? does anyone know? but have also heard it could be the control unit that is faulty, also I have a tappet rattle, thing it might be a worn or leaking hydraulic tappet, how doI tell which one it is? feeler guages? and are they all the same, so I can buy one so I can fit it while I have the rocker cover off trying to determine which one is noisy? Cheers, Gav.
