Apparently when you remove the battery it loses its memory, hope not that is the case.

Ok, I give up.
Scoot was booked in for Monday morning.

Preceeding Friday, after slightly INFLATING the rear, on my way to work, NO warning, BUT, suddenly NO READING from the front!

So....Monday...BMW's diagnosis :
Rear - under inflated...."the K51's will show a warning at a higher presure than the older K25's" that I was used to....like 2.1 vs 1.9....and "temperature can also affect it" ( it was 2.2 and occasionally dropped to 2.1 hence triggered the warning ) Undertandable.
Front - battery is flat...and he showed me on his hand held device....ZAR2.3k for replacement? No thanks.

So off I went.....and since then IT HAS BEEN WORKING FINE....front and back....

I took a TPS which I have done a battery replacement for testing, unfortunately it was not sending a signal. The mechanic told me 9/10 it will not work apparently the sensor is very sensitive and easily damage when replacing the batte

Anyone know if the battery is 2050 or 2032

2032 as far as I remember

Did this yesterday and installed this battery into the rear sensor. Most efford in this job is to remove the tyre. The rest is relatively simple. Sensor is now back online and picks up a reading almost instantly. Thanx for the advise Mike.

I'd rather say the pump is out... way out. Garage pumps are not know for accurate pressure readings.

Edit: And, if I recall, the bike's sensor shows a temperature-corrected value.

Sensors all read 2-4 below actual, no calibration

Revival of the painfull topic, but for what it is worth, Sasol garages have fitted digital tyre inflators.  Key in the pressure and it stops pumping when you get to what you selected.  Pretty accurate as well.  Tested with a separate gauge, spot on.

Actually there is a little trick to getting these things to display the correct (or very near correct) pressure.

Deflate the tyre completely.  When the tyre is COMPLETELY deflated, wake the sensor up with a wake-up tool.  It will now measure and reflect 0.0Bar.  Now reinflate and it should be almost spot on.

That's awesome. Long ago garages used to have this ability, but with mechanical gauges. Who can remember? You turn the knob till the needle shows the desired pressure, then it inflates and you listen for when the "ge-clang ge-clang" sound slows to a stop.

I'm a bit schizophrenic.... my cars tyres I top up at the filling station, but my bike I do at home when the tyres are cold
