New Style Tyre Valves

[GD]

The valves on my car aren't long enough to get a forecourt garage air line on. 
The new valves are silver and have a squarish unit at the wheel then the actual valve.  My valves dont look as long as the cars in the showroom.
The dealer said that forecourt air hoses are rubbish and theirs fit but as I pointed out, at 11 o clock at night when you need a garage BMW are shut.
My car is in tomorrow to see why the heated rear window never switches off, despite the computer saying no fault.  The dealer had said that if the valveis are an issue that has been reported, they will replace them, but an issue means more than me are having problems.  Anyone else had this issue?

can you take a picture and show us. if they are the new style TPMS valves/sensors fitted then a standard air hose will fit them. I use a home inflator, but the valve stem is plenty long enough. it will be interesting to see what you have fitted?

The dealer called and said the valves were all damaged so I challenged them and got the service manager.  The valves are all the new TPMS valves but there is only 4mm to put the garage air hose on. I have them on non BMW winter wheels so he suggested that the stem had been pushed into the sensor by my tyre fitter.
It's a sealed unit so he quickly agreed it wasn't that.

I had the valves on my standard wheel and they are going back on this week with new tyres and I'm not putting the short valves in.  The dealer offered a new set at £155 fitted, but I think that will be just be valves they will fit on the original sensors.  They are £9 each for genuine parts on eBay and £125 a set Including the sensor.

In fairness to the dealer, they agree the stems are too short, but as they are not on  my BMW wheels, they could get out of replacing.  So, they are going to call BMW to investigate, if they won't change them and it's a new set including sensors for £155, I'll pay for them for the summer wheels get 4 valves at £9 and get them replaced on the winters.

I've attached a couple of photos and you see that the dust cap screws right to the flange end and it's not tight on.
