Ok so here is the issue. I replaced the trunk flap kit a few weeks back. All went well and it worked fine when I put it together. I could see where the OE part had failed on one side so I was happy this fixed my issues. Today, it was a bit warmer so I decided to drop the top for a short bit.

I activated the vario system.....top started to open up & then it stopped. Looked back and saw that the flaps were hanging. So I put everything back down and drove home. After inspection, everything seems to look tight and intact. I have the smart-top installed so I activated it and stopped it mid operation. Inspected everything again, all of it looks tight.

It will not open all the way. Stops mid operation as the flaps are hanging. It's like the top is faster than the flaps...very odd. Once it stops, I can mess with it some and get the flaps to go ahead and open up correctly against the trunk lid the rest of the way and it competes the operation. When closed, the flaps are tight against the inside of the trunk lid. They are only loose during the opening operation.

Suggestions??? Thoughts???

Thanks in advance!

I just plan on taking the entire assembly apart next week when i get back from vacation. If anyone can think of something specific I should check, please let me know.

Thanks!

Check for a fault code with STAR. If there is a problem then the computer will store a code. Check the trunk separator contact area.
