Hi Guys,

I've been lurking for a while and finally made the purchase of a 2014 c63 with 20k on the clock. Very happy!

I've only had her a month or so but (very) stupidly made the mistake of mounting the GoPro internally on the sunroof.

Everything was fine until I tried to open the sunroof this morning and I was met with an awful sound of the motor labouring as the go pro mount would not budge. I tried to stop it and remove the mount as quickly as possible but now it only opens half way and when I close the sunroof it goes a step further and lifts into the upright position. I fear the rails have skipped so the sunroof it's now misaligned with the motors.

Has anything seen anything similar? Is it easy to get these reset, or is it a new sunroof unit 😑

Any help is appreciated!

Cheers!

Sunroof or Pano Roof?

Diagnosis is likely similar on both but the repair is going to be vastly more expensive if it's a pano.

Thanks for the reply. It's a saloon with a standard sunroof.

After an hour of fiddling and giving it a bit of force back into the glass recess, the automated mechanism started moving in really tiny steps. I then used the reset sequence, heard a click, and all back to normal now.... Phew! That will teach me.

Good to hear. Brute force and pounding have worked for me as often as, you know, actual tools :-)

GLad to hear! Use some silicone spray liberally to make gliding easier...

Mr Jones

Can you please tell me what the reset sequence is?

Have the sunroof in the closed position and hold the sunroof button in closing position for 30 seconds. This resets the stepper motors. Test by using auto open and auto close. If auto open/close doesn't work, then try resetting again. Same procedure for the power windows. If you ever replace the car battery, you'll have to do the same procedures.
