Hi,
I took my car in for its 2nd service recently, having covered 18K miles. It's a 2.0 TDI 150hp, 2018 SEL-Exec. Model.
I have noticed the tick-over speed remains unusually high for what seems like an extended time, following initial start-up. Even after covering many miles, with the temperature gauge confirming that the engine is warming-up correctly.
Tick-over has typically been around 750rpm, ('ish), but seemingly following the service it's now around 1,100rpm and very noticeable.
I am putting this down to either the colder mornings we are now experiencing or something has been altered during the service. I have to say though, this is my second winter with the car and I have never noticed it before.
Does anyone have any ideas please ?
Also, this thing scares me to death in any slippery conditions - it seems to have no traction whatsoever and even trying to climb the modest gradient off my drive, during a recent hard frost, had the thing spinning the wheels ! (The tread depth on the standard P7's were confirmed at 4mm (F) and 5mm (R) during the service - Again, any ideas please ?
Your advice would be much appreciated.
Many thanks
