Roof doesn’t always work.

[jackboy]

Hi,

Got a strange issue with my z4. Haven’t really driven it much the last year. Just re mot’d it because it’s ULEZ compliant. Weird thing is the roof doesn’t always active. Whether putting it down or up I press the button and nothing happens. I turn the car off and on again. Try with engine running engine not running. Suddenly it will just work. It has never not worked eventually but it’s obviously annoying.

Any ideas? Thanks

possible that the roof control module is starting to fail or the loom is needing repair?

when it works does it work slowly and has the motor been relocated?

Motor was relocated by Bowser and then also had the pipes replaced. When it works seems to go normal speed

Had a similar issue. New module fixed it for me

Hi, I still haven’t tackled this yet. On another forum somebody said more likely to be be wiring than control module. If I try a new (second hand eBay) module will it work without being paired with my car? Also, are there any videos of how to actually do it as can’t find any. Or any instructions?

Thanks

Simple plug and play. Behind the left seat there is a square grille on the trim. Pop this off and you can see the module. Small hands help but you can swap it through that hole.
