Ok. So update. The original installer had not coded the Brink towbar to the vehicle and missed a fuse!! Result was five error messages.
Local Brink dealer had to code (maybe re-code) to the car, reset the relay and insert a fuse. Now working fine.
I am not sure if it was the original installer or an issue with the Brink wiring harness.
Now it has all been reset will try again to see how it goes. So fingers crossed.
