Just tried mine and found that if the boot is open, or just unlatched, the roof will stop at the spoiler and refuse to budge further. I don't want to muck around too much with it so I didn't try to turn the nut and see if you can still wind it down with the boot unlocked.

After viewing that video I understand a little more about the operation however and really wonder if the broken bits would affect normal running, especially stopping the roof exactly at the spoiler.

Mine's over three years old and the roof is used almost every time the car goes out so I'm wondering about lubrication of the runners. Has anyone done this and what was used?

If I recall correctly lubrication of the runners is part of the scheduled servicing in the handbook, don't remember the frequency, if it actually gets done is another thing.

Re: 500c roof only goes as far as the spoiler.

Yes I agree there. I don't think those broken clips are the cause it's something more sinister. Interestingly, when the roof is wound fully open and you try to open the boot, the roof will automatically move to the spoiler position. When mine is at the spoiler position it moves back to position 1 so it's like the car thinks that it's fully open.

That could be because it's learned that it can't go back further than the spoiler and therefore that's the limit of travel. Do you still have to hold the button to fully close it from position 1?

Re: 500c roof only goes as far as the spoiler.

No, just a single press will do it.

Thought not. I reckon all the initialization procedure does is establish the maximum rearward travel and then it applies a pre-set programme for roof operation.

In your case the roof may be jammed at the spoiler so the controller has assumed that that is the limit. Suggests maybe a mechanical problem with the two arms that fold the window and move the spoiler down.

Yes that's what I'm thinking. The fact that even manually winding it comes up against a point where it not budge.

I think I will have to watch that video again. Hopefully I can work out how to get to that mechanism without taking the whole thing off.

I can only wish you the best with it. I'll be interested in following your progress though. I've already learned a good deal about the roof's operation from this discussion. If there's anything I can check for you on my roof (short of dismantling it!!) please ask.

500c roof only goes as far as the spoiler.

Thanks. Haven't started on this car yet as previous one will be out of the paint shop in a day or two and will need a good clean before it goes up for sale.

I think I'm going to try taking the trim off inside and see if I can get to that mechanism. Got a feeling I may have to end up taking it somewhere.

Be aware that the roof adhesive has been banned by eu and you might struggle to get any.
