The coolant red warning light and buzzer went mental 2 days ago. The temp went shooting up. I stopped and checked for leaks etc. Coolant correct level and had dealer 40k service a few weeks ago and the car is a June 2018 model.
The temp dropped back down to 90 degrees and I aborted my journey and the temp gauge was variable on the way home.
Called Lookers Newcastle-upon-Tyne and knowledgeable salesman advised me NOT to drive it and call Skoda assist who recovered the vehicle and arranged an automatic courtesy car.
Collected my Superb today & it was a faulty secondary coolant pump which is apparently a common fault on these 2 litre VW diesels.
Fortunately everything was warranty but if it had occurred in 3 months time it would have cost ITRO £300-£400 which made me glad its a lease car.
However my replacement is T6 4motion same engine...out of the fat into the proverbial!
