I've noticed that new BMWs no longer come with the metal valve caps.

I've also read that it's something to do with the TPMS. Is this correct? Can I buy the metal ones and fit them safely or will they seize up?

I had metal dust caps until they seized last week. Luckily I got them off with mole grips, however they split. Read somewhere they can corrode and seize. Luckily did not damage the valves in the process of removal.

I now have plastic ones (grey) however struggled finding them in that colour. They don't look as good as the metal but blend with my silver wheels well.

Heard of a few seizing up when I posted a thread about some shite nicking my plastic ones

You can buy a load of plastic ones circa 50 for about £2 on flea bay.

A bit copper grease on the steel wheel cap threads prevent the seizing up.
TBH, not noticed if mine are still steel or plastic.

I can confirm mine are light grey plastic, I woudn't have noticed if it wasn't for this thread!

Mine are plastic, on my F30 LCI. I put a pair of metal ones on my previous car, E90 LCI and they corroded, requiring new valves, costing me around £150.

Don't.

I blew 2 valves after they all seized on my winter wheels .

Stick with plastic

+1. I needed a spanner to get them off, and they split, but after I tried putting some air in at the fuel place and couldn't get the metal caps off the valves! Thought it was annoying.
