This is one of like 3 videos that actually tells the viewer anything about how the top systems in these cars work. I've been hunting for like a year in my efforts to figure out what makes them tick besides the obvious hydraulics that we all know about. This is probably the best explanation I've seen, by far, and it's going to be instrumental in my efforts to repair my top system- though I'm going to be removing the entire harness so that my whizz kid brother in law can do the soldering for me.

It worked! It's been a rough three summers without the top working. Thank you so much!

Such a professional, articulate, informative and helpful video! I"m having similar issues with my car, which is your car's twin.

Videos like this give me the confidence to do the work myself. Thank you

Great video thank you for taking the time to film and explain this process.

Excellent Video Instructions on both parts 1 and 2 you do a great job of getting to the point with no Blah Blah Blah. Hopefully I can find my issue using part 2 to find the short in my system. Thanks Dude

Thanks A good start to troubleshooting. My roof stopped mid opening. CVM says #12 and #13 control button short circuit. I think this is gonna take some time.

My top suddenly stopped working: First it would only open half way and the rear lid would not open. Then shortly later, the windows would not go down when pressing open button for the top so the top wouldn't even move. For a year before this, the windows started acting weird by not "auto up" when pressing the window button, regardless if I recoded the GM5 module. So I think the GM5 module is partly at fault. This morning, I recoded the CVM II module (convertible module) and GM module and the top started to work again. Nothing visually wrong with any mechanical part related to the top or hydraulics. I have a brand new virgin GM5 module arriving next week and will program it in order to get my "auto up" window function to work again.

WOOOOOOO HOOOOO this worked finally. Thank you! specifically those wires shown at 7:34.

Very helpful, thanks!

Thanks for the video. Super useful to me.

Hey man thanks a lot! I watched this video and Part I too and it is very informative. Made me excited to fix my friend's car's convertible top. I will post an update once I fix it :) !

I have a 325ci and the convertible malfunction is so bad that I won’t even unlatch from the front windshield on its own, but sometimes after manually unlocking the front latch, when I press the button it moves a little but I still have to manually finish it up and pack it away in the back and then the back cover doesn’t latch closed. It’s so bad that the feature that all convertibles have where the front windows rise about a half inch to create a seal on the convertible to is inoperable. Mind you the front widows do not go up or down.

Great video

Front latches will open, raise a little. All fuses good, checked pinch point on top right no broken wires. Getting no power to top lid motor, do these wires in video activate the lid (top storage) Help please.

Great video. I didn’t get to my top yet, but thanks to you I have a ton of info. One mistake (I think) that I found is the last fuse you mention, 45, is actually a 46, according to Bentley manual.

Good work!

thanks so much!!!! i fixed my roof 🥳🥳

Hello can you provide a link for the pa soft 1.4 you used ? I don’t want to spend money on one that might not be compatible thank you

So I had just swapped my pump yesterday and i went to test the top and it went up and did so pretty nicely. But then I tried to put it back down and it unlatched and then stopped. I’m hoping it’s not the pump I put in and it’s a wiring issue. Based on the position it stops which spot on the wiring harness should I check first?

The LEDs when I press either open or close button no longer light up and top does not go down, no noise, as if no power to top at all. Any ideas? Already checked all fuses.

I fixed the wires on the top left side of the convertible top, (2 wires broken). Then my top wouldn't work, only worked when it was inside the compartment at the back and came out 25% then stopped, I checked for other broken wires (second part at the back) removed the screws and saw no broken wires. So now I do not know whats wrong with the car and why its not closing. (Flashing red light still, does not latch or unlatch it self completely dead until I put it back inside the trunk then it comes back up 25% and freezes). I checked pump fluid level and it is topped up, I checked the motor and it spins.

Thanks for great clip

Nice job on the video, very helpful. You must be British - I've never heard "solder" pronounced that way, always as "sodder", with a silent "L". Apparently that's an American thing...

can you not raplce the whole loom
