Tyre pressure monitoring

TPM reads 2.4 and 2.7, I have set the pressures and checked them with two different gauges which read 2.5 and 2.9 can you recalibrate the TPM?

I moaned about it to the dealership a while back and they didn't mention that it could be recalibrated...if you find out different...let us know.

I’ve always experienced the same problem every 6.000 or 8.000 KM, and the only way I found to solve it, was to take the bike to the dealer tech service, so they can recalibrate it.

Just got back from 12 days touring in the Alps (~2400m) and experienced a different reading from the TPM every day - from 2.3-2.5 front, 2.7-2.9 rear. Temperature or altitude may have affected the readings but in the end I can only assume BMW have cheapened up the sensors, etc, since those on my 07 F800S never varied to this extent, certainly never showing a different reading after a short stop (at traffic lights!).

The dealer has to recalibrate TPM after every service is part of the job and does so by adjusting a special tool over the tyre pressure sensor at the same time he has the BMW Test PC connected to the bike.
So think that TPM and every good hand held tyre pressure instrument plus the digital metters on some gas stations have to read the same all the time, no matter temperature or other. they =at the same time= have to give same reading if not go for recalibration.

Costas - thks for that. I'm due for a 6000m service in Oct so will flag the requirement.

Bike has just had its 6k service and the tyre pressure monitor has been tweaked (as someone predicted) so now reads reliably and without random variation - so if you have concerns raise them with dealer.
