Dropping fault codes
 

Whats the best way of dropping the fault codes on my b3 90? I've got a Ross tech interface from when I had an S8 and I wanted to use an adapter but speaking to Ross tech it's not compatible.

Probably fuse method

the later 4 plug ecu version works with vcds.

Apparently, as my diagnostic plugs are three wire and not four, the adaptor for my interface won't work. That's according to the boffins at Ross tech.
