BMW 1 Series Dead Power Seats: Causes & Solutions

Had the same issue in my 2018 BMW 2 Series diesel. The power seats completely stopped working last month. Turned out to be a faulty wiring harness connector under the seat, which was causing intermittent connection problems. Got it checked at the dealer since I was concerned about potential electrical issues spreading to other systems. The connector had some corrosion and needed replacement along with a section of the wiring. It wasn't a major repair in terms of complexity, but definitely needed proper diagnostic equipment to pinpoint the exact problem. In my case, it wasn't just the memory settings, the whole seat adjustment system was dead, just like yours. The error code was spot on in identifying the electrical connection problem. I'd suggest getting it checked soon since faulty electrical connections can sometimes lead to bigger issues if left unattended. The fix was straightforward once they identified the problem, and the car's been running fine since then. Make sure whoever works on it has experience with BMW electrical systems.

Thanks for sharing your experience. It's really helpful to know it was the wiring harness connector in your case, sounds exactly like what I'm dealing with. Would you mind telling me roughly how much you ended up paying for the repair? Also, curious if you've had any other electrical gremlins pop up since getting it fixed? Really want to get this sorted properly the first time around.

Hey, glad I could help! Just wanted to update you on the costs since you asked, it ended up being 95 € to fix the faulty cable connection in my BMW 2 Series. Pretty reasonable considering I was worried it might be something more serious! The mechanic got it sorted quickly and I'm happy to report the electric seat has been working perfectly since the repair. Haven't had any other electrical issues pop up either, which is a relief. Actually, it's quite funny looking back, I was really stressing about potential electrical gremlins spreading through the car, but it turned out to be such a simple fix. The seat controls now work smoothly with no problems at all. So based on my experience, I'd say if your symptoms are similar, you're probably looking at the same kind of straightforward repair. Just make sure whoever works on it knows their way around BMW electrical systems and you should be good to go!

Thanks so much for all the details! I actually took it to a certified mechanic yesterday after seeing your first message. You were spot on, it was indeed a wiring issue, though mine was slightly pricier at 150 due to some additional corroded parts they had to replace. The mechanic showed me the damaged wiring and explained everything clearly. Really glad I didn't put it off any longer! The seat's working perfectly now, and they did a thorough check of the other electrical systems just to be safe. Everything's looking good. Such a relief it wasn't anything more serious! Definitely learned my lesson about dealing with electrical issues promptly. Really appreciate you sharing your experience, helped me avoid a potentially bigger headache down the road.
