How to fit tyre sensing valves to a BMW?
In 2011, I bought a 2010 BMW 520d touring and a set of extra alloy (327 style) 17 inch wheels with 225/55 R17 run-flat winter tyres. This year I traded the car in and bought a June 2014 320d xDrive Touring. I kept the winter wheels from the 5 series. I had a trial fit of the winter wheels & tyres on the 320d. They fitted fine and ran but the tyre pressure warning system is non-functional. I think the 5 series compared wheel rotation using the ABS system to detect a flat tyre while the 3 series actually measures and displays the pressure in each tyre using pressure sensing valves. BMW says I can't retrofit pressure sensing valves to these wheels and wants me to buy another set of wheels and winter tyres at £2000+. Can you recommend a company to fit pressure sensing valves, compatible with the BMW system, to my wheels?

Sorry, that has confused me. I knew that the original BMW runflat system worked on rotation, but had no idea that they had changed the system for the F30 3 Series. There is a cheap valve sensor system called Tyrepal: www.tyrepal.co.uk/ Otherwise, these people can tell you what TPMS parts are compatible with what: www.tyresure-tpms.com/

How accurate are tyre pressure devices? I gave three different ones and they all give slightly different readings.
If a tyre loses pressure a warning symbol appears on my instrument cluster in my Fiat 500. So why are we always advised to check tyre pressures regularly?
I've heard differing opinions but I understand if a tyre pressure monitor fails, it is an MoT fail? Is this true, if so it makes no sense? Surely the MoT is concerned with vehicle safety? A failed tyre...
