TPMS underreading
My TPMS is showing 32psi/2.2 bar on all 4 tires, yet I've measured (with multiple gauges I might add) a correct 35/2.4 on each. I did the reset procedure (from iDrive) twice, but no difference. Is it normal for TPMS to be off by 10%?

I've noticed mine be off by 1-2 PSI regularly. I'm sure 10% is within tolerance, but if it gets worse than that, I would have it looked at by the dealer.

My TPMSs always read 1 to 2 psi lower than actual pressure.
