A4 heater matrix replacement
Audi A4 Avant, 1.9 tdi, 166k miles
Wet front and rear passenger foot wells to , hopefully, discover whether or not the heater matrix is faulty I shall disconnect both heater pipes at the bulk head and join together with copper pipe, no water loss then it must be the matrix. I'm not looking forward to removing the fascia to check the matrix!
Have carried out a forum search but can't find a thread relating directly to replacing a heater matrix so if anyone can post up a link I'd be very grateful.
The car is consuming approx 1 litre water every 300 miles or so, no sign of leaks other than the foot wells
Any advice will be very much appreciated
