How do i get this light off on my dash - BMW 3-Series (E90 E92) Forum

ac09lude · 09-30-2010, 08:26 AM

The air pressure light came on yesterday morning. I stoped and check my tire pressure and i had 36lbs in the rear tires. i have been driving for 1 day and the light has not gone off. Can anyone help me out?

Sounds like you need to replace a TPS. I would search tire pressure sensor and see what you find on the forums to help you figure it out.

Did you "reset" the tire pressure monitoring system? You have to do that after you check the pressure.

Did you check the tire pressure first?

Did you check your tire pressure today? Maybe you are losing air.

just trade it in!

I'd try the cheap and easy way out first, and try resetting it again. And make sure that when you do the reset that you're not moving until it reads "resetting", I made that mistake once and couldn't figure out why it didn't reset.

reset it

Check your tire for a severe looking "fracture" in the natrual rubber. That may be it as well.

I've had the occasional faulty low tire pressure indication on my left front since I put on new (non-RFT) tires. I've reset the system 2 or 3 times so far. I figure it's probably the TPMS going bad. I'll continue to reset it unless it starts coming on more frequently than every other week.

enycerz · 10-09-2010, 09:28 PM

try to correct the tire pressure in the morning or when the tire is cold then reset it.

Why when i have low pressure , the computer doesn't tell me which tire it is, but just tells me a tire is low? got a base e92 328

Alpine3, I've got the nav system installed and there's a screen for TPMS. It displays the low tire on it. I don't know how it works for non-nav system BMWs.

WannaBModder328i · 10-14-2010, 12:18 PM

i have this same problem, had it reset at bmw too, still on, tires are fine, reset and reset it everyday. nothing works. i think mine is a sensor i'll have them check when i get my rims on

i believe you need a software update...
i used to have just low tire icon yellow or red (!) and nothing else, and it meant that i would have to check all four tires before finding the one that is low. But after software update that i received due to warranty work, now car shows exactly which tire is low...

For the longest, I couldn't figure out why all of a sudden I was being informed of which tire(s) were low on air, especially since my car only showed a red/yellow (!) symbol in the past 3 years of ownership. Then I stumbled on this thread and realized my software was updated...

Is there a way to know what sensor needs replacing?
