Newbie, so please be gentle.
Initially the roof stopped working at the stage where it would unlock at the front but would not raise the roof.
VAGCOM showing codes 01618 - Top Valve 2 (N272) and 01984 - Top Valve 2 (N341).
Looked through the forum and found a number of posts regarding cleaning the commutator and opening the brushes which I have tried but to no avail.
The solenoids were pretty crusty so it looks like moisture has been getting in (High level brake light I suspect) and I seemed to be getting fluctuating resistance measurements across the solenoid terminals.
After cleaning all the contacts I then swapped solenoids 2 and 3 over, cleared the codes, and sure enough the error code went to 01985 - Top Valve 2 (N342).
I have replaced 2 of the solenoids and now the roof goes up and gets to the stage where the front goes up, the rear folds forward and the compartment lid rises. Unfortunately that's where it ends. The lid then comes slowly back down and the code 02000 - implausible switch position appears.
If I press the roof switch again the lid will rise again but nothing more and will slowly drop. Closing the roof from this position still works.
I have tried clearing the codes and manually opening and closing the roof several times but I can't get it to go past the lid opening stage.
Anybody have any ideas. I have attached the log file showing the block measurements up to the point where it fails if it helps.
