TPMS sensor corroded ?

metal licker

Elite
 In the mosh pit
Noticed black marks on the sensor which I thought was just brake dust but on closer inspection it looks like the silver coating has peeled off
The only cleaner used on the wheels is Valet Pro - Bilberry Wheel ( PH neutral) and a soft brush
Anyone else had this problem before I go shouting at my dealership :?
 
Mine don't look very good either :( after the calipers not looking good after 3 months what chance have we !
 
Not sure I understand this - the TPMS sensors are located inside the tyres, on the inside of the valve; how can you see them?

Rear calipers are nearly black,front not so bad I've had this problem with my previous zed and paid to get them painted at my own expense
will be trying to get this fixed by the dealership this time as well as the TMPS problem :x
