I have noticed something odd with the software version on my vehicle.

2020 X4MC
Current I-Step: S15A-19-11-540
Previous I-Step: S15A-19-07-553

The recommended Tire pressure keeps on changing based on some software glitch. Never did that on the previous I-Step version.

TPMS config is set to 20" Winter spec 255, under 160km/h
As per the manual it should be 32F/38R which the previous I-Step showed and never varied.

Anyone else notice this? Thanks

The "recommended" pressure changes as the tires heat up and cool down. As such, you can adjust on the fly, as opposed to waiting until they are "cold'.

This was something different to me as well, until I read another post.

Interesting. Thanks for that info, makes sense.

What I thought was software glitch was a bmw added feature LOL
