Tyre pressure warning not working

[cslau]

My f30 320i original RFT is reli almost running flat today....the best thing is tyre pressure monitor did not warn me :thumpdown: Luckily did not 100% trust these technologies...immediately pull over to check once I felt sumthing strange...else if I hit the highways tats it. The tyre shop fella oso laugh tat he had nvr seen a RFT so flat b4 :smokin::smokin: any such experience guys? Been thinking how to get the dealers to diagnose? Reli no confidence on the TPM now.

You Need to Check if the TPM was activated prior before you had pressure lost...as if the TPM wasnt activated...then the TPM warning wont pop up...
