Hello all,

I have a 100BHP Passat TDI, a few times recently, when the engine has been started from cold the engine immediately revs up & then drops back to tick over ( not somthing you want it to do before any oil gets around the engine).
I have spoken to my local VW dealer, who were unsure what could cause this they gussed at it being a faulty temperature probe.

Any body any ideas?

Regards.
