2020 Seat Tarraco Experiencing Overheating and Low Coolant Level; Potential Water Pump Issue Suspected

Hey there! Had a similar issue with my 2017 Seat Ateca last year. You're right, the symptoms seem to circle around an issue with the cooling system. In my case, the root cause was indeed a defective cable on the pump/control unit. The dodgy check engine light and overheating were clear signs something was off, but this wasn't immediately recognized by my mechanic. The coolant level dropping was the real clue. After a few test drives and inspecting different parts though, they pinpointed it down to a defective cable on the pump/control unit. While it was quite a serious issue (definitely not something to delay fixing), it wasn't catastrophic. They replaced a section of the cable, tested to confirm the new cable's connection was stable and the cooling system was functioning optimally. It was a bit of a hassle, but after the cable replacement, my Ateca was back to its best. No overheating, no weird warning lights, and my coolant level stayed steady. Hope your Tarraco gets back on track soon!

Hey, thanks so much for sharing your experience, really appreciate your insight! Just out of curiosity, if you remember, how much did it set you back to get that cable replaced and the whole cooling system checked over? And has anything related popped up since then, or has your Ateca stayed steady? Just trying to gauge what I might be in for with my Tarraco. Thanks again!

Hey again! Yeah, I definitely remember the cost, stung a little at the time! Fixing the cable on the pump/control unit ran me about 225€. But once it was sorted, it was like I had a new car - the Additional water pump limited function was fixed and I've had no further problems since then. It seems like it's holding steady and, fingers crossed, your Tarraco will do the same once you pin down the issue. Again, it was a bit annoying at the time but well worth the peace of mind knowing the cooling system is working properly. Good luck!

Cheers for the detailed response! Well, €225 does sound a little painful, but it's a small price to pay for a steadier Tarraco and peace of mind. Good to hear that your Ateca has been behaving well since the fix. Fingers crossed indeed, hoping for the same with my Tarraco. I guess it's time for another trip to the mechanic, hopefully a smoother one this time. Thanks heaps for your help! You've been really helpful in calming my mechanic trip nerves. Take care!
