Tyre pressure fault

[slytrue]

Hi, first of all sorry for my pure English. Passat CC 2012 (1GEN)

Please help me to find a reason for my problem. Some days ago, my tyre pressure monitoring has gone..
First tyre pressure warning light comes on, but monitoring show what pressure for all wheels are good (OK). Then (that day) tyre pressure warning light turns on or off in no fixed time. And in end of the day, the tyre pressure warning light come on always, and the weirdest think is what tyre presure monitoring has gone, no longer avalable in MENU. No picture with car and no menu sub category "tyre pressure" (or somethink like that, I dont remenber how exactly it written). Then I connect VCDS, i got this faults:

The tpms module has either failed or there is a problem with the wiring.
Tpms module is behind the rear bumper.
You need to remove the rear bumper assembly.
There is a black control module about 10cm long and 3cm in diameter with a single plug attached.

It's the small black thing with wires coming from it next to the exhaust

Umm.... it's not dead batteries in wheel sensors is it? I seem to recall they are fitted on the inside of the rim in the tires.....?

[kamold]

If the wheel sensors are dead or faulty you will still be able to contact the tpms module. Just won't get a reading from the affected wheel sensor.

BIG THANKS for kamold!! Like you sad all problem was for this TPMS module. I change it and now every think is ok. Thanks for your advice and for picture there is TPMS module location P.S. you don`t need to remove all rear bumper, enought to unscrew 3 screws under bumper and you can easy pull out it. Sorry for my pure English
