Is this mk5 seats going into mk6? Not sure about wiring but there will be a pods issue, resulting in the airbag light coming on.
I want to put a 2010 leather in 2013 but I'm concerned about passenger occupancy device sensor (pods) module compatibility for that swap, both mk6
At a minimum you may need to register the leather seats pods module serial number in the airbag control unit but it may not be compatible. This can be done with a vcds (ross-tech.com). Some people swap the pods modules to avoid this but my understanding is it's a weight sensor system with a number of components, seat cushion, pressure pad, pressure sensor and pods module that are all calibrated together. Swapping just the pods module may negate this calibration. Not sure if even the pods swap will be compatible between mk5 and mk6 though.
