Help please my 2009 A4 back near side door will not unlock electronically. Any suggestions gratefully accepted

Hi and welcome to the club!  :)

 

Does the door still lock or is it both the lock and unlock functions that do not work?

Thank you. It's only the unlock function. I can open it from the inside with the handle no problem. It locks on the key fob every time

Hmm strange sounds like it could be a microswitch or chip in the unlocking mechanism that has failed. Does it still unlock with the key?

Hi im new to the club! Im also experiencing this fault do i need to replace latch or is there another fix wen i stripped the door down n cleaned out with spray it worked again untill i locked doors then back to not opening from outside!

Hi same car same problem. Won't open from the outside once opened from the inside it then opens all the time from the outside  until I lock it again. Any ideas? Did you get yours sorted?

Hi having the same problem but also with the added problem of the child lock being on and Audi are quoting me 125 euro just for diagnostics anyone have any ideas

 

It might.be the drivers door lock mechanism. When this starts to fail it can affect all the other doors as the drivers door controls them all. 

I'd definitely get the diagnostic check carried out though to get the exact fault.

Cheers

Steve
