I was doing some final touch to me Peugeot blind today and this got me thinking. What's parts from other marques have you fitted to audi, why, did you it would work, was it a educated guess or just stab in the dark? For me at the moment its VW Passat engine cover, copied what was done by others. 607 Peugeot rear blind, 100% stab in the dark, no idea it would work. Vauxhall Omega rear blind relay, it was cheap and pin outs suggested it would work. that's me for now. what's yours?
