TPMS Question

[ajolly]

Good Afternoon All,

I recently changed from 16" Spoke wheels with RFTs to 18" 135 Replica wheels with normal tyres. I have only just recently had the thought about the TPMS, I drive an Z4 2005 2.5i, how can I tell if it is the DSC or direct TMS method?

The light hasnt been on since I changed, but I thought it would be a good idea to check.

Thanks in advance,

AJ

The rule I know is UK is ABS Sensors and the US on facelift was the tyre pressure sensors, but I've not heard a lot on how the latter work.

I'm assuming it didn't need resetting when you changed, I'd almost be tempted to take 15psi out of a tyre briefly to see if it flags, not sure how else you'd tell.

I'm guessing you didn't see any strange sensors on the old alloys, but I have no idea how these would work anyway... maybe some of our american friends can suggest how you can tell?

You'll be OK because the wheel sensors weren't installed in 2005, think it was 2007

Yes...2007.

Just another question.... I just took a drive and felt some feedback through the gear selector (Auto), is that normal? It is not when the car is stationary but when I accelerate?

 

[Smokin]

Feedback? You mean a little vibration? Don't know about the auto, but I definitely get it through the shifter on a manual. I would only worry if the vibration were irregular in timing and pronounced.

Thanks Smokin, thats exactly what I mean its a little vibration when I accelerate
