Roof motor problem...

[john-e89]

Bonjourno,

The roof on the M has been down for approx 3 weeks, no previous issues, the other day I started to raise it as normal, remembered I’d got the side top covers on approx 2 seconds after pressing the roof up button, the roof just started to move a fraction, took my finger off the button, took the side covers off, roof wouldn’t play, so I tried to drop it back into fully open using the roof down button, it whined a little but got into position as the light stopped flashing. Pressed roof raised, all I got was a low whine and the roof crawled upwards, stopped halfway, did the same when trying to lower. Now when I press the button I get a very quiet whine, roof moves just enough to make the light flash and that’s it, and I have to physically push it down to to stop the light flashing. Not had any previous issues at all. Car is garaged so doubt it’s a rusty motor but that’s a guess. Can’t think it’s low on hydraulic fluid as not had any previous issues. I’m not really fit enough yet to go removing a wheel and getting to the roof motor and definitely not fit to go inside the boot to look due to broken ribs and scapula not yet healed.

Any ideas chaps...?

I thank you.

It does sound like the eh motor imho as you can hear it but it’s not doing the bizzo properly, even washing a car can drown the motor despite it being garaged
How often have you checked the roof drains are free flowing John? :?

Sounds like you've bent the roof frame John, car is probably a write off now, I will offer you scrap value...because I'm nice :wink:

Have you ever pulled the red handle in the boot to operate manually? If so, the plunger is probably stuck in so always on bypass. Either that of the seals inside the hydraulic rams are leaking. Does the motor sound like it's running OK when it's trying to move the roof?

Oh dear oh dear. One of many a fault then. I'd pull the release cable and see how easy the roof is to move on it's own to eliminate a stiff linkage.
Then it could be a case of if you can hear the motor it could be weak or low on fluid. Could be time for the motor to be placed in the boot
If you need a second opinion and another eye on the job then let me know and I could pop over and take a look with you.

Tbh never Rob, it’s not seen much rain but I can’t vouch for the previous owner.
