The Q5 DOES look great in Black but for me, just too much work to keep it clean.
I see you are not using the Audi roof rack bars that come with the car...because of the bike rack? I guess that aftermarket bars also don't have the magnet that alters the stab system.
Re TPMS, a $350 option. On a 2014, VAG-COM ( VCDS now) can turn it on. Takes a few minutes to do as you have to turn on in three places in the coding. I turned mine on.
