I took my car for a drive today after sitting in the garage a month. And about a 1/4 mile into the drive the flat/check tire warning came on. So, I drive to a gas station and notice the drivers side rear looked low. So I aired it up, then later bought a tire gauge. Forgot mine was in the garage. And got the tire to match the rest of the tires. All the tires are at 35psi. The damn tire warning doesn't go off though. What do I do? And is 35 psi correct?

Searching yielded no results for me.

 

You need to go into the Idrive and reset the tire pressure monitor system. The correct tire pressures are listed on the inside of the drivers door frame.

 

Oh, how do I do that? Sounds easy enough.

 

The error doesn't go away until you reset the tire monitoring in Idrive. The older models used wheel speed to monitor tire pressure, not sensors within the valve stems. The car needs to be parked to reset and then driven a short while to re-calibrate.

 

Ok, I'll try that out, Thanks for the tips guys.

 

Press The i-Drive Button down on the main menu

Then a green screen appears with a whole list of items,

Then click vehicle settings,

once you click it you have to push i drive controller up to scroll within its own menu,

either your system would be FTM or TPM, then when your at a standstill stop, you will be able to click the reset FTM or TPM , then click it to confirm resetting.

Drive away, and wait for it to reset,
