..., which is ridiculous if these batteries only  last 2-3 years this is  then a money making thing considering the cost to replace them at the agents.

Note that these are Schrader TPMS units and not made by BMW.  They are the same units used in the BMW cars, Mercedes Benz, Audi, VW, etc, etc.

Same with the ABS pumps, made by FTE
Same with the brakes, made by Brembo
Even the oil cooler is made by (or for) KTM
The list goes on and on.

Ok, mine started some nonsense this weekend. I had been riding for about half an hour when the warning light came on. The pressure reading remained as is which was 2.3. I got to my destination and then when leaving it was fine, no warning, pressure same. Then, again, after some time the warning light came on. This morning coming to work same story, no warning and presure normal then after a shorter period of time the warning light came on.

Is this also a battery issue???

Your bike is new enough, take it to your local stealer and let them fix it up

Dankie, een wat ek uitgehaal het is 2050, lyk my die verskil is slegs die dikte 5.0mm of 3.2mm

As jy 'n 5mm dik een kan inpas (ek praat nou van die battery ;) ) doen dit so, hy sal langer hou (dikker = meer kapasiteit... gewoonlik).

Playing up again...wtf....BUT it NEVER does it immediately after starting. It seems it 'needs' about half an hour of riding to start its warning, for instance on my commute which is 20 - 25 minutes, it hardly ever does it.

I have exactly the same problem. Sometimes it just gives a dash as a reading, sometimes it gives a believable value. Sometimes after riding for a while, it suddenly gives a warning. Sometimes it doesn't. I don't have money for a new one and don't have time or patience for a battery swop, so I've been riding in Enduro pro with TP off.
Beer isn't the answer. It's the question. The answer, is Yes!

a friend of mine did his one TPM sensor battery replacement last week - similar sensor as BMW, but the KTM has a CR2050HR battery - looks like it has higher capacity and can handle higher temps than the standard 2032 batteries

Most of these TPMS are also available on AliExpress - IIRC around R250

This morning - change in pattern - the RED light came on a mere 5 minutes after leaving home!!!  :o Then, after about 20kms it changed to the 'usual' orange light. Pressure normal.

I think I am going to approach BMW even though my warranty has long expired ( they did, afterall, replace my FD in December...because my service history is 100% etc etc ).

PS...what is the difference in a RED warning light and an Orange warning light?

Unfortunately I cannot find a 2050 anywhere, only the 2032. I have already replaced the battery on an old unit with a 2032 which was quick and easy, still want to take to BMW and see if their test instrument pick-up the signal. If that is successful then will do the original sensor and hope that do not require re-calibration.

Shouldn't require re-calibrating
