Runflat tyre/sensor question..

[PJR]

The 1 series got a puncture today and was driven quite a way with essentially a flat tyre, so had to come the rest of the way home on the back of a rescue truck. The tyre is no doubt beyond repair now (IE, buggered). As luck would have it, I have an identical spare wheel and tyre in the garage which i'll put on the car tomorrow.
However, will the cars electronics recognise the replacement wheel/tyre and work normally right away? Or does something have to be coded for them to work together properly?

Cheers for any input

Ive not got a 1 Series (yet) but from what Ive read on babybmw etc, you need to re-set the pressure sensing which you can do yourself, presumably its in the user manual if you can't find it elsewhere.

Normal procedure is to turn car ignition on, and hold down the sensor button that looks a bit like:



For quite a while, 10-20 secs. Then re-start car.

The button is normally near the handbrake (at least it is on a MINI)

Thanks chaps..
Once the wheel was changed, sure enough, the car didn't recognise it. So still reported a flat. However, the car was due a service anyway, so I just let BMW reset it themselves. its all good now
Btw.. The old runflat tyre split completely on the inside edge!

P,

Out of interest, how far did you run on it, what overall mileage had it completed and what was the damage that caused the puncture?

Another 'out of interest'.. Would BMW tell you what they did to reset it? Presumably it's something that should be pretty common knowledge (and do-able from the driver's seat) as the likes of Kwik Fit etc must be able to reset it when they change a flat RFT...?

LOL, I like the warning message: tyre's flat init!

In the 1 Series you can reset it yourself, from the driver's seat.

On the indicator stalk there are push buttons on the end, in the vertical plane is button 1, in the horizontal plane is button 2.

1. Start engine.
2. Lightly push button 1 until INIT appears in the display.
3. Press button 2 to confirm.
4. Press button 2 and hold pressed for 5 seconds. INIT is shown as ticked.
5. Drive off to allow initialisation to complete.
