Seat Leon start stop error after the vehicle has not been moved for a longer period of time

Hey, I had similar problems with my 2016 Seat Ibiza (approx. same mileage). In my case, the control unit was defective, which led to exactly the same symptoms: Car wouldn't start, high fuel consumption, warning light and flickering lights. The control unit was replaced and reprogrammed in the workshop, and the car has been running perfectly ever since. It's definitely a serious issue, but with the right mechanic you can get it sorted. Good luck!

Hey, thanks for the info! Do you remember how much you paid to replace and program the control unit? Were there any further problems afterwards or did everything run smoothly again? Best regards!

Hey, I'm glad I could help you! Yes, I remember exactly: replacing and programming the control unit cost me €1000. Since I've been to the mechanic, the fault in the engine start-stop system has been rectified and the car is running perfectly again. No further problems since then. Good luck with your repair and best wishes!

Hey, thanks for all the information, that definitely helps me! So I do have a chance of getting the problem under control. I'll probably visit the garage again and hope that my mechanic doesn't do a bad job this time. I'll let you know how it goes as soon as I have more information. Thanks again and best regards!

Hello FimRider, Have you had your alternator or battery checked, as these can both cause the same faults. Greetings Daniel
