I retro fitted the plastic end pieces from the MK7.5 to my car....& modified the OEM MK7 foam pieces...
The MK7.5 is noted for more noise from the front...those foam pieces help deaden the noise in the wheel arch cavity.
I cut the bottom 2inches of the foam pieces, & had to cut recess ion the foam for the tabs from the MK7.5 plastic trim piece to sit into..
To fit the plastic pieces you have to remove the doors & you have to remove them in a particular way due to them being on the air bag & safety sytems....If I remember correctly it was doors open, ignition on (engine off) & disconnect the battery....
Then a simple small tx socket to unto the hinge lock grub screw..& one 12 point for the catch stay..also pull up the top of the door wire harness unlock tab ..remember to fully lower the glass before disconnecting the battery...makes it easier to lift the doors off...two people one to lift the other to guide...set door down some where protected i.e. thick carpet/old curtain..
When refitting get the door back on, harness connected etc...leave door open, & key must be as it was (ignition on engine off)...reconnect battery...
You will get loads of warning lights on he dash which will NOT remove with VCDS as the car needs to be driven for it to "check" that everything is ok...
