Weak Battery and Dimming Lights Issue on 2019 Seat Tarraco: Potential Vehicle Battery Temperature Sensor Trouble?

Hey there! So, I had a similar issue with my 2016 Seat Alhambra. A dimming and flickering interior lighting, weak start, same symptoms you're describing. It really did point to a faulty battery temperature sensor. I got it diagnosed at my local garage and, yep! Busted battery temperature sensor. It wasn't a life or death issue for the car itself, but it's certainly something you wouldn't want to ignore for too long. This sensor is in charge of preventing battery overheating and maintaining optimum performance by adjusting the battery charging rate. So if it's defective, it could shorten your battery life considerably. As for a reliable mechanic, I'd suggest asking around your local community or looking at online reviews for mechanics in your area. It's always a bit of a gamble, but worth the research to avoid getting ripped off. Best of luck with it!

Hey there! I can totally relate to your situation! Faced the same problem with my 2018 Seat Tarraco not long ago. That weak start sign is a real bummer, ain't it? I was lucky enough to find a trustworthy auto repair shop with a mechanic skilled enough to diagnose a faulty battery temp sensor, just like what the other person mentioned. Just out of curiosity, do you remember how much you had to shell out to fix that sensor issue on your Seat Alhambra? And did any other related problems arise ever since you got it repaired? I guess it's always good to be prepared with a rough estimate and potential follow-up issues. Looking forward to hearing back from you!

Hello! Good to hear from you. So, for my 2016 Seat Alhambra, fixing the battery temperature sensor snag ran me up to about 315 Euro. Yeah, not exactly a steal, but the peace of mind post repair has been priceless. Since the mechanic sorted it all out, I haven't faced any other annoying glitches at all. The weak start issue and dim lights were totally addressed and it's been running as smooth as ever. So yep, that temperature sensor was indeed the culprit. Keep in mind it's always advisable to find a mechanic who knows their stuff and won't overcharge you. Hope your Tarraco gets sorted without a hitch!
