Hi all,

New to audi,

Have a 2009 audi A4 tfsi

All the 12v sockets don't work, occasionally the light will come on around them but still no plug will work, I've checked fuses and they're fine? Any ideas?

Sorry no simple fix - you will need to start at the 12V socket and check each of the wiring connections with a multi-meter for voltage/connectivity.

I had figured as much, I just thought it unusual for all 3 to go?

On a separate note, whilst trying to find the issue with the sockets my driver and right rear passenger door will no longer lock or unlock with the keypad or the lock button inside 🙃 codes are- 00446 and 00532

Any ideas?

Those are voltage related errors - what's the status of you battery and alternator and maybe ground connections.; Whenever I see error codes I make a note of them, clear them all and see how quickly they come back. Audi electronics are very sensitive to voltage levels so that typically is one of the first things that needs to be monitored/addressed, especially on older cars as corroded connections can come into play.

There's no issue with starting, starts up nicely, these codes won't clear on both the drivers door electric and rear passenger, however the windows do still work fine to?
