GF has just heard from the car doctors. His comment was "This will take a lot of work and won't be finished today". Sounds a little ominous. GF's nice new Golf is obviously a sick bunny. It seems to have some form of fistula as oil is mixing with the coolant water.
The nice man at the car doctor is contacting VW and arranging for a hire car to be provided at their expense whilst the problem is being rectified.
