Not sure if anyone has posted about this before: don’t ever put an oversized valve cap on the front wheel of a C600 / C650 because there's only a tiny clearance between the valve and the brake caliper.
I put a cap with a built-in valve core extraction tool on my front wheel (just in case I ever needed one while out and about). A few weeks later when I went to top up the air I found the prongs had been worn down completely and the valve knocked about so much that only the cap seal was keeping the air in.
Luckily it was going to BMW for a routine service the next day so they fixed it for me.
I’ve used another cap of the same type for the photo to show what I’m talking about. The prongs make it about 7mm longer than the average cap.
By the way I very definitely use it on my rear wheel only now!!
