Hi
Just noticed today after looking at another f30 I have rubber valves on my 2013 403's, the other F30 2014 had aluminium valves also on 403's, should mine be aluminium. Also have 0001's if that makes any difference.

I do get pressure sensor information ie it comes up on the dash if the pressers are uneven. can I retro fit to the aluminium when I change tyres and will this then give me individual pressure in each tyre.

Thanks
