Re: The tire pressure monitors

The change in pressure with tyre temp is always up from the cold (correct) pressure. A sudden decrease is either a puncture or in your case I would suggest a faulty unit.

Both my 2012 K1600
And 2015 RT compensate for temperature
After a spirited ride pressure indicated on dash is within 1-2 degrees Of when cold
Direct reading gauge can be 5+ psi higher
Somewhere in riders manual it explains it in far too much detail
I'am happy the way it works
Others have reported large errors in pressure readings between bike pressure and gauge when cold, in which case dealer can do a computer reset
My riding buddy just picked up his new 16, riding home from dealer, triangle turned Amber, rear pressure had dropped, within 15 seconds turned Red. He picked up a chunk of steel

Now if he had bought the premium BMW MOA membership his new tire would have been free
Apology 1-2 PSI not degrees

Whilst here, yesterday on a long ride out, my tpm showed a sudden drop from 2.5bar to 2.3, then went to zero, worrying at 70mph on the motorway,
then the amber warning light appeared, this all happened in about a 30 second period, pulled over at junction luckily only another half mile, my buddy carries a tyre pressure gauge, which showed everything normal very reassuring. so from now on gauge included in tool kit.
tpm now ok again after a few more miles.
Okay. Perhaps the specifics of this 'temp compensating' has been lost in translation...! If I have comparable pressures (when measured cold) between the bike TPMS and a tyre pressure gauge, and the bike TPMS then shows a slight increase when the tyres get warm, and then the expected pressure reduction when cold again, then that's the way it should be....Anyway, that's what I experience and what I believe should be occurring.T6pilot wrote: Steve
