    Passat b7 sunroof doesn't work at all

    Hey guys, newbie here. I tried everything with my new Passat b7 sunroof.

    It doesn't move what ever I press. Checked all fuses as well. Please help

    (Covers were removed to check if there was a fuse)

    Whilst I can't help, as I have personally not encountered any problems with my sunroof, perhaps you might find some useful information on topic here:

    Check out fuses SC30, SA4 SA5.

    Have a look at page 94 in the below PDF.

    The sunroof controller also connects to the CAN gateway via LIN, so if you have a scan tool see if it's showing any issues.

    Thank you. Will do this in the morning. Another post said that a weak battery can cause this not to work. Can that be right

    The sunroof controller can fail. I had to replace mine on my R36. The switch looks a bit different on the B7 - its has a panoramic roof - than the B6 which has a conventional sunroof.

    Fuses can be missing because options to your vehicle were never fitted from the factory; number three looks to be present in your image; do you mean 4?

    Did you check the fuse box on the passenger side?

    Is the problem something that just started, or is this a new car to you that came with the issues?
