I've got a 2004 Audi A3 TDi Sport and for the last month or two I've noticed that the coolant warning keeps coming on. Every time I refill the coolant the light comes on again a couple of weeks later, so I'm assuming I have a leak somewhere.
I have looked EVERYWHERE for this leak but can't find it, I've even tried putting a drip tray under the coolant bowl but still nothing. Is this a common fault on Audi's?
PLEASE could somebody help!?!
