Towing Module Touareg

[GREGVW]

Hi all,
Have a 2008 Touareg and trying to get a big trailer (with electric breakaway unit) hooked up. I had the auto electrician install a Tekonsha electric brake controller, I have now hooked up the trailer and the lights are flashing (LED'S) on the trailer. They now say I need a module fitted at a cost of $800 !!! Anybody else had this experience ??

Pretty sure VW have a unit for the treg for this that's about $200... talk to your dealer.
