I can't be sure with a Tiguan but on my 2010 Passat it is a 2-minute job. The switch is on the dashboard - pop it out from behind, disconnect it and re-connect a new switch and pop it back in. With the Tig I'd imagine you have to prise up the gear-lever surround and push the switch out from there.Electronic handbrake switch has broken, how easy is it to replace myself as main dealer want to charge £45 for unit and £90 to fit it for 10 mins work.
any advice appreciated.
