Macan tpms issue

[franki68]

So the macan when turned on says there is an issue with front left tyre with a -3 drop in bar (1.8 vs 2.1) but when I measure the pressure it is 2.1 the actual monitoring display shows the correct pressure as well , just a faulty sensor I think but when I drive it for 5 minutes the warning goes off sometimes at other times it seats on .
Is it just the sensor on the wheel or is it the system ?

I am not too familiar with the Macan's systems, but one way is by putting the TPM back into 'learning mode,' there should be instructions in the manual how to do this. If the error keeps coming back after the learning phase then the sensor might be defective
