Interesting, thanks for the tip! When you say 'acting up', what exactly do you mean? Were you also getting a 'memory lock active' message, or was it something else? And did replacing the battery solve the issue completely, or did you have to do more?

Yeah, I was getting all sorts of random warnings – ABS light, tire pressure sensor errors, even the radio would sometimes cut out. The memory lock wasn't specifically mentioned, but the symptoms definitely pointed to something electrical. Replacing the battery helped a lot, but the mechanic ended up clearing some lingering fault codes to be 100% sure. Honestly, I'd recommend getting it checked by a professional; they can properly diagnose the issue and make sure everything is working correctly. Could save you some headaches down the road!

Just wanted to share that your suspicion was spot on! The auto repair shop checked the car electronics and confirmed undervoltage was causing the memory lock. They cleared the fault codes, did some checks, and it seems to be running smoothly now. The bill was 240€, as expected. Thanks for your help!

Sounds frustrating! I had a similar issue with my Seat Leon – it's a similar generation. I kept getting random error messages, and the control unit seemed to be acting up. Have you checked your battery lately? A weak battery can cause all sorts of weird electrical problems in these cars. It might be worth a look before you start tearing apart the whole system.
