keep finding car unlocked

[lukecollins]

I have a 55 A6 and keep finding its unlocked. The remote is left on the desk so I am sure its not pressed in error. when I lock it again I notice the remote flashes several times when the button to lock is pressed and then on the 2nd attempt it locks. Any ideas?

It sounds like there is a problem - if you unlock it accidentally it should lock the car again after a minute or so unless you open a door.

Mine did this after an earth fault with the convenience ecu. This ecu works locks, windows, alarm etc. Mine was fixed under warranty but it needed a dealer to diagnose

i noticed also the mmi settings for the stereo ie fader, bass, sub woofer also resets to default ie central position on the screen when it unlocks the doors, if this helps. if you know where the problem is please advise or where i need to check the connections. thanks in advance.

Mrs had a VW Beetle and next door had a VW Golf. Every time she opened her car it also opened next doors.

Sounds like the central locking is grounding through your radio, check all the earth points as a start, Haynes Manual Time me thinks, I bet theres loads!!

Not sure that there is a Haynes manual for an A6 and MMI. The instruction book for MMI is thick enough, a Haynes Manual would be enourmous, imagine the circuit diagrams
