Hi All,
A bit frustrated..losing water from somewhere,I have had new expansion tank cap,new thermostat & housing,water pump & timing belt..a new housing at the back of engine which showed staining of possible leak..Still it is losing water,cannot see any leaks anywhere cost so far over Ł700.Had a head gasket test (sniff test),can anyone point me in any other places to look..my local garage has given up,now they have had my well earned cash!!I have even put some K-SEAL in,to hope it can find a leak out of sight.Still losing water though.The car is an Audi A6 Avant 1.9tdi 2001.
Any help will be appreciated.
