2021 Seat Tarraco Hybrid Experiencing Electrical Failures at 170,284 KM

Hey, I can relate. Not too long ago, jumped through similar hoops with my 2016 Seat Leon ST, which seemed to have a mind of its own. After a deal of poking around under the hood, the mechanic finally pointed at the control unit's cable connection, and you guessed it: the culprit was defects there. A loose connection would've been a walk in the park, but this was a whole different ball game. This cable connected the control unit to the BUS system, which is a major communication lifeline for the vehicle's electronic systems, including the nav and speedometer that you mentioned. It was a serious pickle indeed because a crappy connection could mess with every electronic gadget, from the infotainment system right down to the warning lights on the dash, just as you're experiencing. I won't kid you, it wasn't a quick fix because tracking down a specific faulty cable in that unit is akin to finding a needle in the proverbial haystack. Long story short, they had to replace certain sections of the cabling and reset the control unit to get it back to normal. If yours is the same problem, I'd say don't wait too long, it doesn't usually get better on its own. Good luck and hope this helps!

Hey there, your situation hits way too close to home for me. Thanks for filling in the details about your ordeal with the control unit’s cable connection. Did you happen to keep a hold of the bill for your repairs? Just trying to get a ballpark figure here to prepare for the shock. Also, since you got this issue sorted, have you noticed any other gremlins popping up or is your ride running smoother than a hot knife through butter? Let me know. Thanks again for your input. It's really been a life-saver!

Hey again, Know what you mean about those repair costs, can really make your heart skip a beat, right? My visit to the mechanic did leave a dent in my pocket with a bill amounting to 155€. They replaced and fixed the defective cable connection of the control unit which communicates with the BUS system. Yup, speaking in layman's terms, that's the wire that lets all the gizmos and gadgets in the car chat with each other smoothly. Can tell you this much though, the cost was well worth it! My Leon's been running as slick as a whistle ever since. Thankfully, haven't had to deal with a single nagging gremlin poppin' up post-repair. Seems that taking care of the cable connection eligible my ride for a straight 'A' in Communication class, if you catch my drift! So, hang in there. A visit to the garage might seem painful now, but it'd be worthwhile in the end. Afterall, it's always about the journey, not the destination, right? Keep us posted on how it goes. Cheers!

Hey! Wow, 155€! I guess I'd better start warming up to the idea. And yep, that's a brilliant way to put it - giving my car a refresher course in communication is what I need. Haha! Glad to hear your Leon's ruling the roads. And thank you so much for taking the time to share your story and for your encouraging words. That journey-not-the-destination bit is inspiring too, something to keep in mind while I deal with this daunting ordeal. And yes, I'll be sure to keep you updated. Appreciate the help. Cheers!
