Laguna II Tyre pressure sensors?

Ferris

Anyone know if a lit tyre pressure warning light (Orange warning light that turns off after 30s) on a Laguna II (2001) will cause it to fail an NCT?

The tyres pressures are fine on the car its just that the sensors are faulty.

Give them a call at the NCT centre, surely the can give the advice

Other than that, can you remove the fuse?

It will pass with the light on. The only warning lamps that are part of the test are the ABS one if fitted and the main beam headlamp one.

My understanding is the type pressure monitor works off the ABS sensors : a wheel that is not turning at the same rate as the others has a different circumference, hence it is softer.

So while the tyre pressure light may not be a problem, a faulty sensor may have implications for the braking system?

I don't know what the implications are for an NCT test.

Its a Laguna... so they will ignore the tyre pressure sensors. I know i do ! (any almost anything else electronic in that car).

Just make sure your trye pressures are actually correct before you go in.

No, the tyre pressure sensors have nothing to do with the ABS. The pressure sensor is an electronic unit inside the wheel beside the valve.

There are both types. What you're describing is a "direct" system, what ItBeeMee is describing is called an "indirect" system.

Don't know what type is used in the Laguna II though.

Cool, I didn't know there was such a thing as indirect TPMS. Anyway, the system in the Laguna is definitely a direct TPMS.

Listen lads, thanks for the help, I thought that they would ignore it but I wanted to make sure.

Apparently even when you get a puncture fixed you have to bring it back to the dealers to reset the system - bloody renaults - its not my car thank god.

Not correct, that's a myth perpetuated by wrong information on internet sites such as honestjohn.

In my experience the are self resetting ! It happens every few days !

Either that or a fairy comes around at night and deflates and inflates the tryes at random
