I don’t have a good answer for you, as I have a C 400 GT (which for unknown reasons doesn’t have a TPMS, although your older scooter, as well as the other current scooter, the CE-04, does).
HOWEVER;
1) You have made duplicate posts, and this is going to get messy.
Could you please edit the title and text of the OTHER post, to read something like “Ignore” and “Please respond to other post,” respectively?
Otherwise, some responses are likely to be in different threads, which will be very confusing.
2) Regarding the actual problem:
A) Have you tried running with a cold pressure somewhat lower? 42 seems pretty high to me, so I wonder whether the problem will go away if you start out with, say, 36 or 38.
B) I also wonder whether it’s a battery issue with a sensor. Do you know how old the sensor batteries are in your wheels? Have the original sensors ever been replaced?

Thank you for replying!
In regards to the psi, it is written on my manual that rear is 42psi but I will try to lower it.
With the sensor, the previous owner did mention about a loose sensor or something wrong with the sensor. Was just trying to check if someone here had the same problem as well

The built in battery for the TPS is failing, eventually the battery will die completely and the message will be constant. There are You Tube videos of people changing the battery but this isn't a good solution as it increases the weight of the TPS and makes tire balance much more difficult. The part seems to have been discontinued but there are some Chinese knock offs that will sometimes work (kind of hit and miss) I've bought 4 and 2 of them worked though not as accurately as the original; you need to inflate using a trusted pressure gauge and note the psi reading on the display, use that for a baseline and keep an eye on the actual pressure with the gauge. This is like an oil pressure light, when it comes on the problem is already there and it may be too late. I've programmed my TPS sensors with the GS911, you can enter the freq on the new sensor and it's done, or you can place the bike in "learning mode" and it will find them and sync. Since the bike needs to roll some to get the TPS active, if you want to place the bike in learning mode you'll need an inexpensive TPS turn on tool (got mine from the bay). Good luck and G'day.

Thanks a lot Pappy13!
Any chance you have the link for the knockoffs that worked for you?

I'm sorry, I've made 3 tire pressure sensor purchases, they were all made in China, and it's "hit or miss" as to what will work. I found them on EBAY using the BMW part number,Thanks a lot Pappy13!

2x TPMS 8532732 Tire Pressure Sensor For BMW Motorcycle C600 Sport C650 433MHz
the last ones I bought came from Gangle Products and even had the Schneider(sp?) name on the sensors, but they were just copies of the original.- Thread starter

Awesome, appreciate it! Did you buy it with the valve or just the sensors?

on these scoots the TPMS is separate from the valve. I source the valves separately and change them every 2nd tire. with the TPMS across the wheel from the valve you'll want to keep the original part (as close as possible), this is why I say changing the battery isn't a good idea, the hot glue and wraps of tape make the sensor significantly heavier (I weighed the repaired one and compared it to an unmodified one).

Why not order one from a BMW dealer, they can ship it to you? It is under $200 if you pick up.
However, if the battery dies you're supposed to see "--" in the readouts, like "no value" . Not "High Pressure".
For "high pressure", as well as "low pressure" there are two gradations, yellow blinker and red blinker + actual numbers are shown.
Which one you're getting, and is there a readout (number) shown in the RDC info menu, or "--"?

In a perfect world you would be correct, but with my 2013GT I would get high readings, low readings and the double dash up until the battery died and only got the double dash. The weak battery corrupts the signal and affects the measure until it no longer has enough battery to connect. I verified the readings with my air gauge, I would get a low pressure alarm with a reading on the dash of 18lbs, check with my gauge and have 34lbs, would crank back up, take a ride and the low pressure alarm would again come on, after a ride of 6 or 8 miles the reading would go back to normal, another 15 to 20 miles and the double dash lights up. Eventually the double dash becomes constant but I had already ordered a replacement and was waiting on a tire replace before changing the sensor.
The sensors that BMW offer are "new-old stock", I wonder how old the batteries are , I'm SURE they are better quality than the Chinese knock offs are but are they worth 5 times the cost? With a battery that may only last 2-3 years? I'm on year 3 with one of the sensors and year 2 with the other (year 2 replaced one that failed very early, like I said "hit or miss") These are just another "cost effective" means to maintain an older bike no longer made. BMW ( "break my wallet","bring more Wampum"), their support parts cost are insane.

I installed a Chinese knock-off on a 2013 GT and it worked fine. I used the Motoscan app and a $10 GM wake up tool to activate it. I think the BMW dealer price is absurd, akin to paying BMW $435 for a CVT belt when you can buy the exact same Mitsuboshi belt without "BMW" stamped on it for around $75. Link to belt if anyone needs it: https://www.carpimoto.it/en-US/Bike...67-Mitsuboshi-Transmission-Belt-BMW-C600-.htm
The sensor sits on the middle of the rim in the tire, held in place by one T-30 torx bolt. Good idea to be careful taking the tire off the rim to make sure the tool doesn't scrape the sensor -- I mentioned the sensor location to my tire guy.
Here is a photo of the sensor on a link to the Chinese sensor I bought. They appear unavailable, sorry.

I wonder what would happen if you just ran RDS CAL procedure from SETUP menu, would it work to assign the new "knockoff" sensor or do you really need GM wake up tool?
BTW Delray the $200 I mentioned are Australian, to Australian OP - it's more like $110 in USD in your eyes.
And the new sensors they selling now are shorter and lighter, perhaps not necessitating 35g-50g weights to balance the wheel...

Yes, that works as well (I've done it with my GS-911) then I learned how to just input the serial number from the sensor and have the bike "look for it". As I re-read the post I have to ask if the RDS CAL is viewed from the scoot (mine is a 2013, so if yours is a later version it may have features mine doesn't). But if you're looking at it from a separate scan tool then you may be able to enter the serial number and the next time you ride it works...

In the menu that shows RDS ON / OFF, press and hold the Menu button.

My 2013 doesn't have that feature, 2016 brought a lot of upgrades. Can you get to that screen while rolling? If so, try the cal, or try rolling enough to get the TPS system active, stop, leave the bike running and try the cal then. Probably stuff you've already tried, I just like to know how many ways there are to "trick" the system. Please post back to tell us how you finally got it to work.
