Tyre pressure monitoring with non-runflats

[David-H]

What do those of you who replace the OEM wheels and RFTs do about the monitoring system if you fit new rims with non-runflat tyres?

a) Replace the valves in the non runflat wheels with a set of valves with RDC sensors (£316.49 for a set from Sopers),
b) Take the valves out of the OEM wheels,
c) Just ignore the tyre pressure warning?

£315?... Try £160 - 271823877898

I never fitted them to my winter setup & it brought the light up on the dash. They were only fitted for 5months but if I was keeping them on all the time I would fit the sensors

Something to consider if you are going to be going non RFT permenatly and expect to keep the car long term i.e. Longer than 3 years then you will need to fit the sensors as the warning light on the dash would be a MOT fail.

If you can get them for £160 i would buy them,keeps the dash clear. techathy did you fit them to your car ? Going to look into that myself for my winters.

Yeah, I bought a set of 4 from that seller, they work perfectly. Just install on the wheels, fit to the car & do a pressure reset.

Bit the bullet and ordered a set - total €218 ~ £176 delivered. Hopefully, when they arrive I can just drive to my local tyre fitting place, tell them to replace the standard valves with these new ones, do a reset and then drive home whilst it recalibrates?

Yes & refer to page 84 in your owners manual

Why page 84? :?

[David-H]

Maybe reset has changed as my manual is different to yours?

 

[David-H]

Sensors now fitted - just had to reset in iDrive and then drive away and had 4 greens in a few minutes.

Only just found this.

I was under the impression that replacement wheel sensors had to be programmed with the car's reader on cars built after 03/2014? Not so?

Good news if I've misunderstood this and the sensor pairs automatically..................... Makes a wheel swap a whole lot easier.

Mine E89 is new (registered March 2016) and did not need any programming. Should be covered in the car's handbook?

Check what model you need here [All E89's seem to be 433MHz]

 

[bob4333]

Thanks for the link.

There seem to be two options for my October 2014 car.

One, "Intellisense: Configurable needs to be programmed", the other "HUF: No Programming Required".

Presumably you went with the HUF and all is well?

Anyone know what the other is for? Both are recommended for a post 03/2014 car.

Yes, mine are the HUF and all's well.

Thanks, that's very helpful.

You have to get the right units for your car. The HUF system just detects a sensor and picks up the data. The signal from the unit doesn't seem to transmit any kind of ID just data. I've not got any experience of the Intellisense system

 

[bob4333]

Indeed.

The point that's been cleared up here for me is that there doesn't seem to be a requirement (even on my post 03/2014 car) for the aftermarket sender unit in the wheel to be programmed to the car - which for some reason I'd got stuck in my head was a requirement.

So logically, if I get the same HUF units as DLH a wheel swap should be a more straight forward affair.......?


But as an aside it still seems a wasted BMW opportunity. My daily driver (non BMW) gives me real time tyre pressure readouts together with a reference against what they should be. It's interesting to watch what driving and ambient temperature does to pressures.

 

[techathy]

Some early systems, like the system originally used on the E89, the receiver didn't tell the car what the pressure was. You simply had a simple binary value which was sent to the ECU. A 'reset' would simply tell the receiver module to use the current value from the sensor as the 'correct one' and would send a warning if the value was out. I have a feeling that due to a kickback of this system there is no system in place to report the actual values to anything which can display them.
