Hi all, 2013 Estate 2.0d (168hp) DSG, 138k on the clock, has it since new.
For the last few months my temp gauge has been very erratic, not going from cold to 90 in one go, often going up and down, even hovering at about 75, regardless of whether or not the car is travelling fast or slowly.
I had a leaky radiator so didn’t notice originally, had that replaced and thought that would solve it, but no luck.
My local (not specialist) garage (no error codes btw) then suggested replacing the water pump (and cam belt (?) which was fine as she is coming up to her 10 year service), which didn’t solve it.
We then replaced the thermostat. Still not solved.
Any ideas? Like I said, not getting any error codes.
Would love to get this fixed as have had the car since new and want to keep it till the wheels fall off, have never had a better all round useful and comfortable vehicle.
TIA
