Seeking Insights on Flickering Lights and Weak Battery in 2019 Seat Tarraco with High Mileage

Hey there, I definitely feel where you're coming from! I had a similar hitch with my 2016 Seat Leon not long ago. Noticed some poor lighting and a weak start-up, like your situation. After taking it into the garage, it turned out to be a faulty battery sensor microprocessor, just like you're suspecting. They basically had to replace the whole sensor. It wasn't an overly complex fix but sure was necessary. The microprocessor is the brain of the sensor and when it's acting up, the sensor could give faulty readings, just might be what's causing your dim lights and poor start-up. Keep in mind though, it doesn't necessarily spell disaster for your car. It's not a terminal issue, just something that needs to be nipped in the bud before it affects other functions. Take it easy and maybe get another diagnostic run at a trusted garage to confirm the cause. Good luck with it!

Hey, thanks for sharing that! Your experience with your Leon sounds eerily similar to what's happening with my Tarraco. Definitely gives me a ballpark area to investigate. By any chance do you recall how much this battery sensor microprocessor replacement set you back? And has the problem resurfaced since the fix, or any other unexpected issues? Thanks again for your time and advice. Stay safe!

Hey, I'm glad I could help! To answer your question, it cost me 315€ for the battery sensor microprocessor replacement, which was reasonable given it's such a sophisticated piece of tech. Since getting it fixed, it's been all smooth sailing and no more dim lights or weak start-ups. That sensor error has quit bothering me, thankfully. The mechanic did a bang-up job, and my 2016 Leon has been running like a dream. No other unexpected issues have come up either. Hope whatever is going on with your Tarraco gets straightened out without a hassle. Remember, better to cross your T's and dot your I's when it comes to vehicle maintenance. Stay safe on those roads!

Top stuff! What a relief to hear that the issue hasn't reappeared and everything's been smooth with your Leon afterwards. The price you mentioned for the microprocessor replacement doesn't sound too overwhelming, either. I'll make sure to get this situation with my Tarraco sorted out as soon as possible, even though it may not be a full-blown calamity. Must say, the idea of my Tarraco running like a dream, just like your Leon, sounds pretty convincing. Thanks again for your help, really puts any worries at ease. I'm off to have another run at the garage now. All the best and stay safe too! Cheers!
