Audi A3 door locks

[MrAndyW]

Tried putting this in Audi forum, but no joy so far. Maybe some previous owners on here.

Audi A3 hatchback
2009 1.9 D
Problem with the doors unlocking.

Exactly the same with both keys and new batteries in each.

Press the fob once drivers door unlocks. But on second press within 5 seconds most of the time the other 3 doors do not open. Sometimes they do.

All doors open from the inside,then if you close them with out locking, you can open them all from the outside as normal.

After a bit of googling it seems something called the comfort module,which is in the boot or under the drivers side dash.

Anybody had similar problems or can offer advice.

Thanks Andy.
