Seat Tarraco problems with the electronics after it has rained

Hello, I recently had a similar problem with my 2017 Seat Ateca. My control unit was faulty. The symptoms were almost like yours: the car wouldn't unlock and the lights kept flickering. At the garage, they first checked the battery and the cables, but ultimately the control unit had to be replaced. Yes, it was a serious matter, but after the replacement everything worked perfectly again. I would recommend that you have the control unit checked. Good luck.

Hey, thanks for your answer! Do you remember how much the whole thing cost? And has anything else come up since then? Would like to avoid getting into a similar situation. Best regards!

Hey, sure, I can tell you. After I went to the garage, the fault in the door handle electronics was rectified. All in all, it cost €600 because the control unit was defective and had to be replaced. Since then, everything has been running perfectly again and no new problems have arisen. So, if you are experiencing similar symptoms, I would definitely have the control unit checked. Hope this helps you! Best regards!
