Harri Posted April 28 Share Posted April 28 Any ideas on cause of coolant loss - expansion tank and cap been replaced; pressure test no leaks; no spill under car: heater works (but not great) : not overheating and no other obvious problem - 2 garages now stumped as to what it could be. One suggestion was intercooler but 2nd garage said unlikely and at 1000£ replacement, I'd just like to know for sure the right thing gets fixed! 2014 A3 tdi 2litre. Having cam belt and water pump replaced in next few weeks also. Quote Link to comment Share on other sites More sharing options...
