So took the dog out tonight and noticed a leak under the van on nearside.
Initial thought was oil leak, I've had a light on for past few days but no leak and it was due a top up. After checking again I think it may be diesel. Either way I'm due to drive to Italy in 3 weeks time, if I get my passport but that's another story, so its not ideal.
I've got carista and no errors coming up that could point me in the right direction.
Anybody had similar issue or have any idea of what the fault might be?
I'll add vw to the list next to passport office to phone tomorrow. Could do with a bit of luck this week!
