I have an issue with my a3.
I went to unlock it the other day and a whiz zing noise was coming from the rear of the car near the plastic woofer.'thought nothing of it.
A few weeks passed and I went to unlock my doors to find that they were already unlocked!! Oh dear!
From what I can tell from online is its the pump that controls the locks was whiz zing but no longer locks or unlocks any more so thrown back to the stone age of manual entry. Lol
I've found some pumps online but from what I can tell is that my key is coded with the pump?? And need to either swap over a board or re sync the key??
Any help apriacted
