Hi, can anybody help. I have an Audi A4 cabriolet 1.8T 2003. When trying to open the roof recently it suddenly stopped half way just as the boot lid had opened about an inch. I had to manually close the roof and I now cannot open the boot unless I use the key and the automatic roof switch won;t work at all. I closed the roof securely with the key that is supplied but the dash is flashing that the roof isn't secured. My mechanic reset the fault light but as soon as I started to drive it came straight back on. Any ideas?
