2004 Golf Mk5 1.6 FSI BAG engine

Cruise control inoperable and the brake lights illuminate and stay on constantly when the ignition is turned on when the ignition is off brake light works as it should when engine is running.
Had the following code:

16955 - cruise control brake switch A

I have swapped the brake light switch with a replacement which made no difference. Must be a short somewhere due to the power to the brake lights when ignition is off.

Anyone any ideas or experiences?

Seen another similar thread with no solution anyone got any ideas
