First question I need to ask, what is wrong with your cars parking brake? 

The jumper wire method can actually cause problems and not be the fix, as you have discovered. What have you read so far that made you try the fix?

I used Techstream (older version) to fix my issue. I also have other diagnostics that can at least find the problem, if not clear the codes. 

Once you explain the issue, someone if not me, may be able to help.

Here are some of my experiences - 

Also on later cars the auto release can be disabled/enabled as in this post -  

Also you can blow the OBD fuse if you are not careful. The lights that normally flash when using the paperclip method, are the ABS/SRS lights (EML used to flash on old Mk1 pre OBD2 cars).
