Citroen C4 - Tyre Pressure Sensor pairing

[GiveMeABreak]

From my experience These all need to be done at the same time. My dealer had issues with one of my sensors when I kept getting a warning on one of the fronts - it took them 4 attempts. As soon as they calibrated it, it was ok for a few minutes, got down the road and warning back on again - took it back, then recalibrated, then off again and the same thing happened, but this time it was another sensor (and these were all replaced with new ones under warranty a couple of years previously. Took it back again and then he explained he had to recalibrate all 4 sensors again together instead of trying to do just the one. No worries after that.

So I just wanted to pass that on as you said you've just done one of them....

As for the equipment this is what Citroen use which works in conjunction with Diagbox. I'm sure there are other exciter tool type systems that do the same sort of thing though.
