Tyre Pressure Monitors

[Donniepat]

My bike se agterwiel pressure monitor gee n intermittent reading op die dash. Partykeer vat dit verewig om die lesing te gee. Partykeer vat dit so lank dat ek warning van pressure kry en dan ander tye gaan dit aan soos normaal.... Batterye in sensor of miskien n fault code wat reset moet word? Enige iemand dit al ondervind?

Ek het dieselfde gehad. Terug gegaan BMW toe, hulle het die agter sensor vervang en alles calibrate weer.

[JABO]

Ook dieselfde gehad.
Is n geseelde unit so hy moet vervang word.
Wonder wat gaan gebeur as almal se batterye begin pap raak.

I was told to disconnect them. Never work properly.

Klink soos 'n battery wat pap word.

It is possible to replace the batteries.  Less than R10 for two at Dischem. 

There is a video on YouTube of someone doing a RT.  I used the video to replace two on a GS successfully.   The main issue is getting them out and back in as the tires need to be removed.

For some reason - its back online as per normal....

My front wheel did the same a week or so ago.  Weird, but my guess remains a battery on the way out.  My wife's 09 did the same a few years ago.  Failure became more frequent until it stayed dead.

Mine does exactly the same (2014, 42k km). New units are crazy expensive, so I've just gotten used to is.

If you buy tyres from BMW would they automatically change the batt or do you have to ask?

Being a sealed unit, BMW do not replace the batteries. They only replace the whole sensor. Therefor Bear's DIY option of replacing just the batteries.

My 2015 GS start with the same problem 2 weeks ago, 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. Could there be other problems, any other advise?

Usually these symptoms indicate that the battery is going flat.  The TPS and ECU can loose comms with each other for a period, but that does not happen often.

Got a quote this week - R2200 per sensor plus labour.
They did mention that it could just be calibrated. I should be so lucky ....

Phoned Bavarian today and got the same answer

You need remarkably few tools, but DO need a simple GLUE gun (hot melt type).

Both those videos are complete hack jobs.  You stand a very good chance of pulling the copper tracks off the circuit board below the battery.

At position 3:19 in the second video he is lifting the side of the battery where the lower tab attaches to the board.  He is just lucky the tab broke off the battery side.  9 times out of 10 it will break the board side as that is the weaker position.

The correct way to do it is to remove the surrounding sealer all the way around and then desolder the battery from the board.  Then replace with a new battery with the solder tabs, not the ones he is using.

These are the correct batteries to use.


I do them like that all the time and very rarely have them fail soon again.  Did one for Mickey recently.  AFAIK it is still working well.

Yep still working perfectly!!

My previously buckled front rim that you straightened for me is also still Mint,
I still think you need to move to Jozi, we need a TOP CLASS mechanic like you here
