I have a recently purchased a 1.8 20v 4x4 estate that has the factory towbar set up.This may seem like a numpty Question but do you need to cut the bumper to access the electrics ?

If it is a Westfalia removable unit, the electrics should be on a drop down bracket that can swing down from behind the bumper cover.

 

The pivot should be visible as it is bolted to the towbar beam, behind the bumper. If it  hasn't been used in a while, the pivot may require a dose of WD40 on the pivot bolt to get it moving again.

 

Hope it helps.

 

 

Thanks for the reply..I thought it may pivot but was not sure how,I will give it a good spray of "please release me" tomorrow and hopefully get it moving.
