I changed my rear hatch, I bought one that was on an R32. I swapped everything over from my original hatch to the new one. The R32 had a different loom and a dual aerial in the rear screen. The R32 spoiler was identical to the GTI. I took the spoiler off of my original hatch and sold it. The spoiler is attached to the hatch with 2 big dobs of sealant at each end. I used a bike brake inner cable slid under the spoiler and I cut through the sealant with a sawing motion. The spoiler is then clipped to a plastic bracket that runs the length of the hatch, I used a plastic trim tool to lever it off. I was unable to get the plastic bracket off without breaking it. The guy who bought it bonded the spoiler onto a non GTI rear hatch, without the plastic bracket, with windscreen bonding sealant.
