I have an astra twin top. The boot wont open, the roof and windows wont go down and there is an alram going off when ever I go over 20mph

There is some help in the link. They don't like being paused half way. There are also sensors to stop entrapment.

So! I just happened to have the same problem with my Astra H Twintop, too! I opened the roof and as I started driving, I started hearing this annoying noice, signaling that the boot is open. Then also I could not open/ lift the trunk more than 5cm and it appeared to be stuck like that with the roof fully opened.

I opened the ski trunk between the back seats and as I started checking with a cam the inside of the trunk in order to locate the ECU unit in order to try and release the boot to open manually, I noticed that the trunk net (which needs to be pulled in order for the roof to be able to open) had closed itself! No idea how this had happened, as I had placed the net correctly in its seats at the back to the right and left. But still it had managed to release itself without anyones assistance, while the roof was opening.

With the help of a long umbrella (or you can use just about any stick, which is at least 60-70cm long) and a lot of patience I managed to extend the net back to its rightful location, so that it is fully stretched in the boot. I tried opening th boot manually first, which did not happen, but what a surprise - as I pressed the roof-closing button it took place naturally without any hassle and so the problem was solved.

Still Opel should had though of some mechanisms to keep the net securely locked, and not allow it to subtract, if it sits a bit loose in the two pockets. I hope this helps someone, now I can finally reward myself with a beer.

i know few
error codes/ fault codes, wiring diagrams, schematic diagrams, torque specs, engine info, switches functioning, assemble, disassembly, complete refurbish, repair, installation every single thing is covered
within seconds u can get the access and it's totally illustrative complete

-Roof will not cause that. Shaking steering cause from un even wear front tires.


Good luck

These are electronic so the first call is the fuse box.
If not it may be the electric lock has packed up . Check your manual as there may be a manual overide cable.
If not it needs to go to a dealer as they have tools to release it.
It may also be that the roof safety mechanism hasnt engaged properly (this is to prevent the roof from being damaged when the boot has opened) . Again this can be checked by a vauxhall dealer.
P.S 9 out of 10 times its the fuse.

You need to pump the hydraulics manually, to do this first sit on boot and press boot button for a few seconds without allowing the boot to open. Partially allow boot to open, manually push boot all the way open and closed a dozen or so times to manually pump hydraulics. I had same prob, this sounds extreme but does work and wont cost you a penny.

Sounds like maybe some pin switches for interlocks have gone bad. Open your trunk and look for the rubber booted switches and try holding them or shorting them, if you make the top move it shows you which ones are bad.

the astra convertable is prone 4 this problem take it to vauxhall there is a rework and it wont cost u a penny!!
