Roof fault - not found by dealer

Pretty sure 5.0.6 does work with the E89. You may have been given a translated interface without the E89 headers on the main page. Try the E90 menus if you are just reading codes.

You could try downloading a fresh copy of BMW Standard Tools 2.12 and use that. I don't have a link to hand but search bimmerpost and you will find a few links.

Alternatively you can use a mobile app to read the codes. If you have an Android mobile you can use MHD Flasher to read the codes from your car for free. (You would need a £2 OTG cable to connect the USB DCAN cable to the phone).

If you have an iPhone you can use an ELM 327 v 2.1 WiFi adapter and the free version of "Carly for BMW" to scan codes.
 
Apparently warranty work is not very lucrative for the dealers and I was once told that they don't get paid for the time to investigate and diagnose the fault. This all means that this so called 'premium' manufacturer doesn't put much effort into these sorts of problems. This is no excuse though for those who've paid through the nose for the diagnosis!

My first Z4 had an intermittent roof problem. They claimed they couldn't find the fault although the roof would fail at leat 2 times out of 3. They explained that it could be a micro switch but that BMW would not countenance a fix by trial and error - they had to identify specifically which micro switch was at fault before they were allowed to fix it under warranty.

As I climbed into the car I said "so when I put the roof down now it will work?" "Yes" they said confidently. It stalled half way and refused to move up or down! Huge embarrassment followed by a "we'll fix it, sir". "But you still don't know what the fault is" I said. "How come 5 minutes ago you couldn't fix it and now you can?" Anyway, it was sorted under warranty. Premium brand my arse!
 
Yeah recognise the symptoms I had the same . The worry is you will be somewhere and the roof won,t go down or up. Mine was a micro switch which after replaced all was back to normal. If your in warranty keep pressing the dealer, if not look for an independant with more moderate cost structure.
 
Quick update - got in the car this morning (roof up overnight obviously / not been roof down for a couple of days).

As soon as I reversed the car off the drive, BONG BONG BONG 'Roof System' then 'Roof not latched'.

My software doesn't seem to talk to the onboard computers, so completely stuffed. BMW dealer is 5 miles away from my house.... really pissed off about it now.

Haven't re read this but have you video's this on your phone - I have done that with this car and my Smart car ... and the dealer used the video to reinforce with the warranty people that there was an issue. It got me a new sat nav unit with Smart and oddly also a Sat Nav screen with BMW ! Both intermittent faults - the Smart particularly so !!
 
I'm going to have to keep an eye on my roof. Dropped Mike off at work this morning, jumped out the car, put the divider down in the boot, back in car and went to put the roof down. Roof folded into the boot but then I thought it taking too long and looked behind me and the lid was stuck open at about a 60 degree angle.

Then I got the error message re the roof. Didn't want to be stuck down there with the roof in that position. Moved the car across the road, switched the ignition off and then back on and the green light came on and I could finish the job. Tried it again when I got home and no issues but now I've had one I'll need to keep an eye on it. I'll also get the diagnostics on it to see exactly what the fault was. I'll also put my car cover in the boot on the off chance it happens again and I can't fix it.
