^^ This. If the top can't "see" whether the trunk is closed or not, it won't open.

Skip the reader for now. You're already describing symptoms of a torn trunk loom in the accordion.

I diagnosed and fixed the typical broken wire above the driver's seat, everything else checked out in terms of continuity. (And up to this point, it was so easy I thought I was a genius.) When I re-plugged everything in, the convertible top LED would flash, but neither button did anything. After about 20 seconds, the light would go out and still nothing would happen. Cycling the key does nothing either.

If I unplug the module and re-plug it, the same thing will occur. When I re-plug the module, there are slight noises as if the hydraulics are being pressurized. The top is currently folded into the cover, but it will not latch. The same thing happens when the top was up but not latched.

I did discover that my trunk lid will not unlatch with the key fob or the button by the footwell. Also, the trunk lights do not come on when the trunk is open. I thought I checked all the fuses. Any guidance? Is there a common pass-through for all the trunk wires, including the hydraulics? Do I need to break-down and bother someone with a CVMII code reader?
The accordion is the common pass-through you're thinking of.

Thanks Taylor192 and cvx5832, I will do a search on the forum, and it sounds like I have some work to do this weekend!

90 degree days in Pennsylvania without the convertible are killing me.

This e46 forum is definitely one of the best sites on the internet. Literally saving me $1000's in repairs!!
I finally have a real car.

Can someone add this to the first post.


Operation of the softtop will be electronically locked out if there are electrical issues with the trunk.
- Check if the button on your key opens the trunk
- Check if the trunk release under the dash opens the trunk
- Check if the trunk open light is on the dash

If any of those checks fail, then a trunk issue may be locking out operation of the softtop, ie pushing the softtop buttons does nothing.

I just repaired my top using the information here. Excellent help, and thanks to everyone for contributing. My top was stuck just prior to latching. I forced it up by hand and held it open with a block of wood so I could access the wire harness. I had to remove a retaining clip inside the joint above the driver's window with a torx driver, then slice open the nylon sheath with a knife and scissors. The break was obvious, so I spliced a bit of stranded wire that I pirated from an old microwave in my basement, and soldered. I then taped up the splice, taped the nylon sheath, replaced the retaining clip, and it worked! Total time, about 20 minutes. Total time to find the tools, 15 minutes, so the repair itself was 5 minutes! Big time and money savings. Thanks everyone!
