Hi all,

So my Sharan has developed a common problem to this engine (AUY). Checking on internet, lots of people have it and are trying to work it out, but no obvious cure.

Car runs smoothly when not under load. IE low speeds and not up hills. Once I put my foot down the temp gauge shoots up and oil goes up way too far too. There has been coolant loss and the internal cabin heater blows cold air.

So far replaced water pump(there were signs that coolant had come out near the pump previously, but not wet) - this wasn't broken though and thermostat. Car now in garage for a new rad. I hold out no hope this will work because I have seen so many other posts where same repairs done, but haven't worked.

Took it out for a test run after the new pump put on and ran it up a few hills. Temp gauges went crazy and coolant level went way, way above max level. Had to open coolant reservoir, losing it on road....... then top up with water because the level then dropped down below min. Then had to limp home because the temperature kept moving above the 90 mark.

Pressure test done and head gasket seems fine.

Anyone out there any ideas PLEASE???
