Good afternoon all,
I recently purchased an A6 Avant 3.0 BiTdi
After returning from a 60 mile round trip on Sunday I parked up and noticed that I had left a trail of water that dried white very quickly in the sunshine. I assumed that it was condensate from the air conditioning but the white colour didn't seem right.
I used the car yesterday and had the same result when parking up after a 10 mile round trip.
I went to work today and there was no water trail when I parked up after a 14 mile trip.
When I left I checked under the car and it was bone dry with no white stain.
Upon returning home the Emissions Control light came on.
Anybody got any ideas what both these could be?
Thanks in advance.
