IDUA

I’ve decided to trade the car in today as the list of niggeling faults are getting longer and longer, I would like to thank Gareth for his reply, it’s forums like this that support other drivers with their car “troubles” and can make owning a car that little bit easier.

Hi all, I own a Audi A3 2.0tdi (150bhp) ive got a unusual problem, day to day it runs fine, now and again my wife will do a 50mile round trip with a couple of hours gap, when she returns home and parks up all is well, the next morning when she leaves for work the expansion tank will be empty of coolant? 2 garages have checked for leaks both have pressurised the system with no loss of pressure reported, all mechanics and technicians scratch there heads. Any suggestions??
