Another tpms thread

[Peloquin138]

After I had a tyre replaced for the mot, along with the valve, the car (64 plate focus estate) has been flashing up "Tyre sensors not detected". 

 I phoned a place today, the only one I can find around Stoke, that does them and they want £50 to pair up 1 wheel. 

I've looked on YouTube etc and tried all the methods I can. 

I've got the horn to sound and the message "Train front left " but when I left air it out just keeps going. I just dropped the air from 4 2 down to 10 and nothing until I repressed the valve (I stopped as the tyre was getting so low) and the horn sounded twice and the message changed to "Tyre not trained... Repeat) 

I filled the air again and tried again with the same result. 

I'm officially stuck... Any ideas?

Cheers folks.

Maybe an obvious question but when the tyre shop replaced the valve did they replace your TPMS sensor/valve with a standard rubber valve instead?

The receipt at the time included the valve and it was 35 quid so I'm assuming it was a sensor one.
