Hi,
The same thing happened with my car (2.0 tdi 150 hp) several days ago. I called the skoda help and they offered to tow my car to the nearest dealer center. It was Friday evening and they said they could not do anything over the weekend, so I am waiting now what they say on Monday. I bought this car in February 2018 from an official dealer, it was 3 years old and 90000 km driven. When the engine overheating happened the car had 130k km on the clock. All service have been done in official skoda centers. I wonder whether the dealer can cover some part of the spare part and labour cost also here in Finland (if the problem is with the pump)? When I spoke with skoda help, the guy on the phone said that this problem is quite common in Finland also.
