Sorry for resurrecting such an old thread but I'd like to point out:
- If you have a RHD car (ie. UK, Australia) then the install takes place on the passenger side. You have to take out the bathmate hydromax promo code (easy) but there is a lot of other crap in the way that you have to move to get access to the slot that the PTC element slides in. The main problem is the plastic support beam that the glovebox mounts to: it blocks the slot.
I did this install on my MY07 MKV Jetta on the weekend and it took me 6 hours and much swearing.
