...on closer scrutinisation, perhaps the convertibles were aluminium? Seen 2 sport backs and it was like a Matt grey colour, to match the rest of diffuser... but the strip is still there, just not aluminium.
Ps: the strip is easy to remove from the diffuser too - about 5 screws
Dave email me you address and I will send you some glasses ,no charge🤣
Thanks Andy that's what I have been trying to say all S5 have the strip. Some look silver others look grey. The official colour from Audi is platinum and the part no fits both early (2007) to later(2015) S5"s. The difference is the valance size.
Dave valance has 3 torx screws on the bottom attached to spare tyre well, then 2 further screws,1 on each side above your back tailpipe that connect to the side of the bumper.
Like Andy says 5 minute job as you just release the clips and it's off.
