Hi,
I had  my ADV stopped for 2 weeks and when returned from my leave and riding the bike, the front tyre pressure monitor just didnt show any measure; just __:__. When testing with the GS 911 everything looks normal, no error code. Is it possible that even with no error code showed the TPMS doenst work? If so is it a problem of the batteries inside the sensors? If for any reason the sensor codes writen in the ECU desapear is there any other way to re-write them as on my 2 sensores there's no 6 digit code label where we can copy it and write it through the advance settings..

I assume you have looked at the following link;
http://www.hexcode.co.za/products/gs-911/procedures/rdc

Does your GS-911 show the "Current ID: {7 digit-number}" for wheel set A, front & back?

Normally, when the battery of the sensor goes down a certain level, your dashboard should have shown the infamous yellow exclamation mark plus "RDC !".

According to the user-manual, only when "--" or "-- --" are shown plus the general alarm (red exclamation mark) there is a malfunction of RDC system.

Please be aware the sensors only go awake above 30 km/hour.

I would try option 2 in the aforementioned link;
- First take a ride for 5 minutes, ensuring that you have reached the speed above 30 km/hour for sure, for at least a couple of minutes.
- Upon return, the sensors should be "life" for at least 15 minutes when the speed is 0 km/hour, so hook up the trusted GS-911 and see if any error-messages are recorded.
However, as stated on the aforementioned link, this is *not* the right way to relearn the sensor. (!)

If you want to relearn the sensor-ID, I guess you must wait at least 20 minutes or so (after riding), and use the Emergency method (Option 2: waking a sensor manually), by leaving a substantial amount of air out as described in the aforementioned link.
(make sure you have the means to bring the tire back to its correct pressure).

PS: You can replace the batteries of the sensor;

SeripGSADV:
Dear,
Thankks for the support.
GS 911 doesnt show any sensor ID for wheel set A front and rear, and the yellow triangle is ON.

Inspector Gadget:
Just to be sure;
I guess there also no sensor ID's shown for wheel set B either, right?

Are you using the GS-911 beta software or the "regular" v1303.3 version?
You may want to try both software-versions, just in case, to double-check.

If the above doesn't help and the described emergency-method (letting air out for at least 10 seconds on the front tire) does not wake the sensor either, and the GS-911 software does not report any faults, I guess you need to consider visiting your BMW dealer then.

Ask them to record the sensor-ID's for both sensors for you on a piece of paper, using their RDC tool.
You then go back into the GS-911 software and enter these codes yourself and have them available in case of future issues.

If the BMW dealer can't seem to wake and record the sensor-ID's for you, it might indeed be that the battery is flat of that sensor(s).
And, whilst you are at it and depending on your standing relationship with that BMW dealer, you may want to consider requesting them to hook-up your bike to the BMW diagnostics, record any faults (and perhaps erasing them) and see if (via the secured internet-connection) any software-updates are available for your BMW.
Sometimes the BMW dealer do charge a "nominal" fee for it, so you may want to check that prior to that endeavour.

Also, as you are there already, again depending on the standing relationship with that BMW dealer, you also may want to request a printout of the repair-history & also check any outstanding recall-actions.

Jughead:
I have taken to printing out the TPM Sensor IDs and pasting them inside the client's service book.  That way, if there is ever a failure, I can just refer to the book and enter them manually.
