How to revive a4 cabriolet roof motor.
How to manually open audi a4 roof.
Remove the sunroof switch from the headliner take the switch itself off the mount and you ll see the contacts underneath.
My audi a4 has a manual crank spot under a flip cover just in front of the roof on the ceiling.
If your roof is opening randomly it may be just bent contacts for the switch this is known on the a4.
