Thanks for all the replies. We’ve checked everything that’s been suggested and, having gone through the control panel again, we think it is something to do with the roof/battery. We hadn’t put the roof up for a while ( or used the van for over 3 weeks) and, although it looks fully closed, there’s obviously a problem somewhere. I couldn’t upload the ping!
Have you checked the hidden VW diagnostic menu on the Control Panel?
For those of you who don't know, if you ever get any problems with roof stuck or any other error say with the heater or fridge, you are able to access the hidden menu in your control panel as used by the VW Engineers.
Access as follows:
1. Hold down the centre of the rotary button together with the menu button (button below with the squares on it)
2. You will get the hidden menu.
3. Rotate the rotary button to get to "VW diagnose" and select this by pressing on the centre of the rotary button.
4. If no errors are present it will display "no errors"
5. If Errors are present then a list of errors will appear . Make a note of any codes.
6. Press the centre of the rotary button again to delete all the errors
7. Repeat process above just to check that errors have dissapeared!
8. Re-configure the time and date if neccesary.
9. Switch off using the L lower button. Wait 30 secs and switch on using L lower button.
Any problems should be resolved assuming these are Electronic and not Mechanical.
