Question about Fischer Railing support TopLine

Yes, but only if your 2018 VW Tiguan has the correct longitudinal roof rails. The Fischer type list states that the Tiguan II (AD1) from 2016 onwards is compatible with this system, with a maximum load capacity of 90 kg.

If you could tell me whether your Tiguan has open or closed roof rails, I can help you work out the compatibility more clearly.

What do you mean by open or closed longitudinal bars?
