Just wondering if anyone has experienced the below, or has any idea what the issue could be.

I tried to drop the roof on my E93 tonight, then realised the boot cover wasn't​ in the closed position. Opened the boot, closed the cover and shut the boot. I then went to drop the roof again, now the i drive is saying there is a roof error. The windows won't roll back up with either the individual window buttons or the button that opens/closes all 4 at once, in addition to this the boot won't open (unless i use the key).

When i try to open the boot there is a clicking noise coming from the rear right hand side of the car. Could this be a failed relay ? Would the boot, windows and roof mechanism all be on the one relay ?

Hi Chris,

First off, I don't have a solution. But I do have an e93 330i and am a paranoid about having a similar issue at some point. I have just ordered a C110 diagnostic tool from Amazon Prime having read good reviews (£37), I would imagine that it would inform you of the exact prob/component failure? I'm expecting it to tell me what components to change to loose all the ABS/brake lights that popped up yesterday.
Back to your roof. Apparently the blame quite often lies with one of the 2 relays in the boot well (as you are considering). There is info on youtube about replacing the relays - looks straightforward. Hope you get it sorted without resorting to going to a specialist - or worse



PS My rubber roof seals needed lubricating badly, there is great stuff called 'Gummi Pflege' (rubber care) worth using if you don't already.

Cheers Wolfgang,

Relays bought this afternoon from BMW (£30), will swap them over tomorrow and report back.

Well, the relays were easy to replace, can't say the same for trying to get the battery cover off.

Still the same problem, so looks like it's a sensor issue. As i was talking to a BMW tech yesterday, it dawned on me that the car has just got back from the body shop, tech guy said to take it straight back to them as they may have moved / dislodged a sensor.

Just a quick one- my diagnostic tool C110 doesn't show folding roof issues.

There is a rubber grommet on each rearmost corner of the roof tray.
If one is missing then that side of the tray doesn't seat properly for the sensor to detect that the tray is down.
I had this problem, fortunately I found the grommets rolling around in the boot.
