Roof problems with 946 Spyder. Help needed!

Our Spider is a beautiful car with a stubborn nature. We`ve managed to solve the problems with the engine, but not the roof issues. Thatís why we`re looking for help from this Alfa community on following issues:

ē How to adjust the tension on the roof. When the car is passing through holes or otherwise twist its body there are crack noises both in front and in the rear of the roof. I suppose there is a place that needs some tightening, but I have no idea where is it? Help plz.
ē Of course there is a problem with the roof closing. After I browsed everything in this forum and tried to pull/push emergency cable, checked the level of the hidraulic fluid, etc. it seems the problem is somewhere else. It turns out that if you isolate this sensor Ė take a look at the images, the roof opens and closes. The question is where to find this particular sensor because here in Bulgaria we doesnít have access to such part. Ideas and suggestions?

Any other hints & ideas are welcome!

Happy riding

I have the same problems with the noises when hitting bumps and grids etc...
I only get from the front though and I know of no way to adjust the tension...
Following the post though...

Like Alfadisiac, I can't help you either, but am interested to hear of anyone else's experiences.

I'm actually considering asking around for a recommendation for a good local BMW indie to solve all my roof issues.
The mechanism on the older 3-series is very similar to that of the Spider, and there's a hell of a lot more BMW convertibles out there so logic says someone somewhere will know their way around it, unlike Alfa dealers/agents.
The only option I seem to have in NW England is a main stealer.
They seem to have neither the skills nor the knowledge, though they'll happily take £100 + VAT per hour off you nevertheless, and that quickly adds up as I know from experience .

I had problem with my hood during the spring. My AR workshop worked on it and redid all calibrations during 3 weeks. I had problems with hood failure when closing and finally it stopped during closing procedure. My mechanic said there aren’t any instructions on how to do it so all it was trial and error. The hood is developed by a German engineer and it’s not impossible that BMW is using the same roof.

I'm guessing the Spider's roof is from the same manufacturer as the BMW's, though of course smaller than the 4-seater Beemer. The opening & closing procedure looks similar to me.

Interesting youtube clip: https://www.youtube.com/watch?v=boiybaJkMrI showing a guy carrying out a manual operation on a 3-series.
The flaps and trunk procedures appear a little different.

New issue started yesterday.
Chilled out, 60mph cruise on duel carriageway for 20-25 mile

Rear of roof (rear window) popped 3 times.
Luckily I have the smart top fitted so I never had to come to a dead stop to re-tension the roof.
Did it once on way to work this morning but had roof off on way home (got caught out in a quick down pour too)

I lubricated all joints on Monday, and to roof seemed to come off quicker today

I never have my roof down when there's even the slightest chance of rain.
I have nightmares about not being able to get the thing back up again .

Are you giving it a good spray with WD40 or using something else?

I've never had a problem putting the roof back up, just taking it off...

I've just given each point 2-3 quick blasts of wd40 with a rag behind to catch any overspray.
