Had my car hooked upto Vagcom today and it threw back 2 errors.

This one and another one which I know what it is.

What does this one mean though?

possibly a poor earth contact in the door, probably caused by water ingress (that seems to cause most electrical issues in the door)

Get the door panel off and carefully look over all the loom, especially where it goes through the A post. You may well have a broken wire. If the control units loses power it will show a communications error.

If everything is behaving itself, it could be a code that has not been cleared after a previous repair.
