Driver door not opening with central locking

[avant rob]

ok as title, the door wont open unless you climb in pasenger side and open from inside. been intermittant for a week or 2, guessing its a solenoid of some description as replaced fuel filler one already, seems electrics getting worse on audi as rear wiper dodgy too. new shape b8 58 reg s line avant. any info appreciated, part numbers drawings etc to get to the bottom of this gremlin!

Has nobody else had this problem at all? its now 95% of time dodgy but as its about 5 degrees outside and snow now. So its not a good time to strip to bits just to take a quick look, rather get part and do it all in one go.

Hi There

I had this problem with my A4 passenger door earlier this year.

I came across this thread, https://www.vwaudiforum.co.uk/forum/showthread.php?...

Basically there was an idea (don't know if true) that the locking mechanism had somehow become unsynchronised, so that the outside handle wasn't at the same position as the inside handle. The solution was to keep on opening, closing, and unlocking and re-locking the door so that they become synchronised again.

It sounded daft to me, but I tried it, and haven't had a single issue since!

Also, be careful when opening doors, I believe this problem can be caused when, say, a passenger has their hand on the handle pulling it, just as you have the unlocking button pressed.
I always make sure my passengers don't touch the handles until I have definitely unlocked the car now!

It's worth trying for free anyway!

thanks ill give this a try. its now pretty bad as only opens by handle outside once in blue moon now. going to have to strip door down i think if anyone has advice on hidden clips and screws please let me know im pretty good with the tools but dont like yarking at things especially if theres still a screw in lol.

OK for anyone who is interested the problem is now fixed, after many of hours on the net i found part numbers. 8J2837016A. on youtube i found a guy showing pics of removing the door card doorpannel remove audi a4 B8 - YouTube this proved usefull, if your handy with the spanners then this is a diy job. The main problem i had was refiting the new part as the door handle lock is on a short metal bar with plastic locating pin which you need to locate almost blind into the mechanism, this took me about an hour on its own lol. The part was £90 trade from tps but was quoted £99 from main dealer. Tps say this is a very common part to be sold as its used throughout the vag group. (nice little money maker)

hope this helps someone.
cheers Rob.
