So you say that this interface is compatible with some programms and only needs to short together the K and L line. My brava 1999 80 16V uses only the K-line and i tried the Uniscan Visa 1.83 Interface and reads and erase faults also, but it works only in DOS and uses two com ports, so you must have an old PC to use it. I attach a picture for what interface i am talking about. If anyone wants any further info for that interface feel free to ask me.
