Hello all.

Only for interest, but just in case you didn't know..

The only requirement for pressure monitoring is as Phil says.. when you change the front to the back you will need to re-code the transponders.

These sensors are battery operated and send a signal to the ECU at either 12mph if moving or every hour if stationary.

If a tyre becomes deflated or a tyre is replaced, once the tyre has been re-inflated to within accepted pressure parameters and the vehicle exceeds 12mph, the ECU will reset itself and the MIL light will go out. However, if you damage the valve during tyre replacement, a new valve would be required and would need re-coding.

If you changed the front tyres to the rear and you chose not to re-code the sensors, if you had a puncture on the right hand rear.. your puncture would show right hand front instead. The engine management light would also stay on until re-coded.

For information. replacing the valve through an official Renault dealer would cost :

£22.00 + vat for the transponder valve
£3.95 + vat for a fitting kit?
£53.05 + vat for removing the faulty valve/ refit and re-code.

The only test our engineers haven't carried out is what happens if a 'blow out' occurs.. does the car go into limp home mode? We will let you know what happens next week!
