Vehicle: Skoda Fabia TDI 1.2L diesel
While driving back home, the car suddenly stopped accelerating and the RPM was stuck at 1000, even when I applied more gas.
Immediately after, the overheat icon started blinking. I pulled the car over to check if there was any coolant left in the reservoir but it was totally empty and the radiator was still spinning.
I let the car cool down for a bit and filled the reservoir with water. Within a couple of minutes, the radiator stopped spinning. I assumed that this indicated the engine cooled down enough. I drove for a minute or 5 and pulled it over again to check the coolant reservoir, to see it's empty again. The car hasn't moved since then.
What I've noticed is that whenever I shut down the engine, the radiator keeps running for far too long. The Engine Fault indicator is always active and the service center says it's probably some wiring issue and that the problem is resolved. However, it keeps returning.
Can some one help me understand what exactly happened here:
1) Why did the car suddenly stop accelerating?
2) How to overcome the heating issue ?
3) What can I do about the engine fault indicator ?
