Marco Polo Pop up Roof Failed - Help!

[danecycling]

My 2017 MP Sport pop up roof failed this weekend, after taking my son for our first trip together.
This was the sequence of events

• Leisure battery fully charged (12.9 V)
• Roof raised fine when first set up to camp
• came back to van ready for bed (beds set up etc) and Westfalia console continuously beeped with Roof Up error
• Roof would not lower in the normal way (battery voltage ok).
• Switched on ignition, 2 tone beep was heard.
• Locked van and came back 10 mins later - continuous beep still going.
• Lowered the roof in the Emergency way, switch under the cooker and lowered bit by bit.
• Alarm stopped sounding and no errors seen.
• The next day I tried to roof again and immediately the alarm sounded again, so closed the roof.
• Plugged the van into the mains, and the beep started again (with the Westfalia screen showing the plug)
• The next day tried the roof (not plugged in and 12.5V) and it would not move.

I have tried to reset the Wesfalia controller using instructions from here - still no luck.

Please help.
Suggestions welcome, before the inevitable trip to Mercedes (but I really don't trust their experience in the Camper side).
Thanks.
Dane

Ive no experiance of your system but loads with a Bongo. There may be a limit switch that has not engaged. this was a problem i ocassionaly observed with tired gas struts once replaced no problem. i dont expect struts to be your problem but limmit switch might. Once i had put extra weight on roof (solar panel ) it required the occasional manual assist at the limmit. Most Bongo owners have engine running whilst lifting roof.
