Overheating and engine indicator light on Skoda Superb: Possible auxiliary coolant pump malfunction?

Hey sports fans, I currently have a few worries with my Skoda Superb 2015, petrol engine, 196500 km run. The part is overheating and the check engine light is on. I suspect the problem is due to a malfunction of the auxiliary coolant pump. Had a rather lousy trip to the garage recently, so I'm reluctant to go back. Has anyone had similar experiences before and can give me tips on how it went with the mechanic? Thanks in advance!

Hey, I can well understand why you're hesitant to go back to the garage. By the way, I drive a Skoda Octavia 2018 and had a similar problem, the car got way too hot and I also had this check engine light on all the time. At first I thought it was nothing serious, but it turned out to be a pretty serious fault, unfortunately. It was the water pump that was broken. They had to replace it completely. It was quite a bit of work to remove the thing and put the new one in, but after that the problem was solved. So, check whether it could be your water pump instead of the auxiliary coolant pump. In any case, modifications to cooling components are not without their problems and must be repaired correctly, regardless of where the fault lies. Good luck, buddy!

Hey, thanks for the tip about the water pump. I'll definitely keep that in mind when I talk to the mechanic. Good to know you've solved that now. Can I ask what you ended up paying for it? If it was also the water pump and your cost point was fair, then I'd be reassured. And has anything else come up since then or is your Skoda now running again without any problems?

Hey, no problem, always happy to help! So, after I went to the mechanic, they fixed the problem with the auxiliary coolant pump. It was quite a job, but fortunately my Skoda purred like a kitten again afterwards. The repair cost me just under €390. It wasn't cheap, but the turbocharger coolant pump had to be completely replaced. Since then, the car has been running perfectly again and there have been no further problems. I hope you have similar luck and that your Superb runs smoothly again! Good luck!

Thank you very much for your detailed reply! It's reassuring to know that you didn't have any further problems afterwards. The cost is a bit high, but I think it's worth it when the matter is finally resolved. I think I'll just go to the garage now and have the water pump checked. Hopefully everything will run smoothly again after that. Thanks again for your help and see you next time I have a car question!
