Seeking Advice on 2021 Seat Tarraco's AC Issues and Potential Ambient Temperature Sensor Malfunction

Hey there! I had a similar issue with my 2018 Seat Ateca. The culprit was indeed the ambient temperature sensor feeding incorrect data to the engine control unit. It was messing up not only the A/C but also messing with the engine starting routine. It wasn't an extreme issue, but it's important to tackle it once identified to avoid potential bigger problems later, especially with engine functioning. In my case, the problem was with a faulty cable and plug connection from the sensor. The mechanic found it during a routine check. It required a bit of diagnosis though: testing the sensor, the wiring, and finally the connection. But once it was sorted, everything got back to normal. Just make sure, if you decide to sort it out at a garage, they know what they are doing. It's a straightforward task for someone experienced, but if done wrong, it could lead to further complications. Hope that helps! Stay cool.

Hey there! Cheers for sharing your ordeal, that's really helpful. Sounds pretty similar to mine, so looks like I might be dealing with a funky sensor cable as well. Can you recall how much you spent to get it fixed? And, fingers crossed it's been smooth sailing since then but have any related issues popped up ever since you sorted it out? Would love to know just to prepare myself for any surprises down the line. Thanks a bunch!

Hey, no worries! Yeah, my Seat Ateca did cost a bit to get that ambient temperature sensor issue squared away. The final bill came to about 95 Euro. That was mostly to straighten out the defective cable and plug connection from the sensor. A bit steep, I know, but considering how it helped improve the car's overall performance, I reckon it was worth it. Since getting it sorted, I've not had any related issues crop up. In fact, the AC has been humming along perfectly, delivering cool air just like it used to, and the engine start doesn't stutter anymore either. Just bear in mind, once it's handled properly by a good mechanic, things should be smooth sailing. So, get your hands dirty and tackle this head-on. Cheers!

That's great to hear. Seems like that 95 Euro really paid off for you! Perfect working AC is a must, so I don't mind paying that price either. Haven't noticed engine stuttering yet - here's to hoping that stays consistent! And I appreciate the encouragement. I've got my game face on ready to tackle this head-on. Thanks once again for your valuable insight! Cheers!
