Confused! Do Z4Ms have tyre pressure sensors or not?

As per the title.

I'm confused. At some stage in the not too distant future I'm having the 224s I bought off a forum member refurbished to replace the 19" "CSL style" replicas that came already on my Z4MR. These are brand new with new tyres but just not really to my taste.

There seems to be no issues with the TPS system with these. (not that I've actually driven the car!).

The recently acquired 224s don't seem have any tyre pressure sensors on them and so after a bit of reading on here I was convinced that E85s don't have them and the TPS runs off the ABS sensors. Hence all I'd need to do would be to swap over the wheels once they've been refurbished and I've bought new tyres for the 224s.

But then just now I read this ad for a Z4M and it mentions having had new TPS sensors.... :?

Can someone enlighten me please?

Throttle Position Sensors... nothing to do with tyres

They are the cause of many a fault code and not unusual to have been replaced. There's 2 in the engine bay area and one under the throttle pedal.
 
its a different type of setup that doesnt use TPM on the rim... i think its an abs sensor based system

This.

It uses the ABS, although iirc USA cars do have sensors.
 
Whatever it has, it doesn't work well i got a 7mm bolt in my rear PSS last year and nada showed up on the dash :roll:

Looks like it's an ABS relative wheel diamiter/speed system on Euro/UK cars and went to valve stem monitors on facelift e85/6 for USA models only. USA systems discussed here on Pelican http://www.pelicanparts.com/techarticles/BMW_Z4M/22-SUSPEN-Tire_Pressure_Monitoring/22-SUSPEN-Tire_Pressure_Monitoring.htm
 
However
You may after fitting new wheels
Get the tyre monitor come on as mine did
Popped myself as was in middle of no where
Apparently a bmw thing when fit new wheels
Simply held button down on dash to reset and clears itself:)
 
No. As others have said, the Z4M uses the ABS sensors to monitor wheel rotation. When it senses a different speed side to side, over a period, it assumes the tyre has deflated and pops the lamp on, or at least it should. I also don't think it works so well. :roll:
 
Meanwhile
Over in the New World ...
Canadian Zeds have no in tyre wheel sensors.
They use the ABS System as buzyg stated.

Apparently American Zees do have a pressure sensor in each tyre.
I have sensors in my snow tyres which I purchased via Tire Rack in the USA.
You can tell you have sensors if the tyre valves are metal.
When Tire Rack discovered that they had sold me $200 worth of unnecessary sensors,
they refunded my charge account ! :thumbsup:

USA and a few other countries as well starting with 2007 models but not the UK as noted above.
