tyre pressure sensor

[Ryza]

hi all,

wonder if one of you could help here...

6 weeks ago i bought some new 17" wheels for my 03 cooper.... these were put on the car no problem (no warning light).... today i had to take the wheels back due to some of the powder coating flaking off....

so they just put my old 15" alloy wheels back on....when driving home the tyre pressure warning light came on (flashing)....so i stopped at the petrol station to check the pressure as the tyres are not runflats.... admittedly they were at 24psi...so inflated to 30psi all round.... unfortunately the light is still flashing...

does this require a reset ....if so how do you do it?? :(

your help would be appreciated..

Make sure the tyre pressures are the same on each axle, then, with the ignition on, press and hold the tyre sensor switch until the light goes out, start the engine, then, even although the light may still cone back on, drive off for 200 yards or so to allow the sensors to react.
If this does not work, you can keep the button pressed whilst driving along an even road surface, the light should go out

thx bud

sorry to sound daft but....pressed the only button i could see...which is the one for resetting the trip counter....

Is this the same or is there something i'm missing..... not very technical....

Its the button near the handbrake, that's got a wee picture similar to what the fault light shows.

the light doesn't go out when you push it...it stays on constantly. turn the ignition to position 2, then push the buttontill the light goes on constantly. start the engine then it goes out once you've driven off a bit.

The explanation in the owner's manual is probably easier to interpret and more than likely has diagrams to ;)

gentlemen....excellent....tried it just there and all is well...

thanx

[Gorbash12346]

the reason it has done that is due to the differemce in rolling diamters of the two sets of wheels as it is only designed to detect a difference in this measurement and therefore any change of trye presures, tyres, and it should be reset

[KenL]

I try and reset every now and then. I always do it after adding air to the tyres. I imagine it is definitely required if you get new tyres and/or wheels.

Procedure is stupidly complicated in the R56, OK for a clever chap like me :p but I can't imagine an oldy like my mum or dad coping with it :eek:

[Gorbash12346]

you get used to it though... after about the 4th or 5th pdi :(

[Ryza]

thanx again people...

Sounds like you've got a punture

[Sweeney]

depends, did it *bong* when it came on and it was red? if so thats it meant to have detected a puncture.
If amber/orange its telling you theres a problem with the RFI
