Hey!

I want to buy Bimmercode because I want to disable TPMS check.
All I really need is a Flat Tire Monitor.

I noticed that bimmercode has this coding function:

Tire pressure control
The displayed values of the tire pressure control in the iDrive system. Please note that the car has to be equipped with the required sensors to make this work.

Values:
>Display pressure only
>Display temperature and pressure
>Not active

Have you tried disabling this function?
Does this prevent the car from checking the tyre pressure?

Bimmercode cannot defeat systems that are considered necessary for safety. As for setting TPMS to only show a flat tire that's a bad idea. Low tire pressure results in excess tire wear, poor road handling and high fuel consumption.

[RAZERS]

I know but in my E90 I got only FTM and it's enough for me.

[Billfitz]

So long as you manually measure your tire pressure at least monthly that's OK. Few of us do, and I'd rather know about a tire losing air before it goes flat, not after.

[RAZERS]

OK, I asked bimmercode support and this option will not disable TPMS.
I had to use E-SYS.

Btw I don't think you were checking tire pressure every 30 days on your car

[Billfitz]

No, I don't manually check my pressure every 30 days, as my TPMS will tell me if my pressure drops below 30PSI. For that matter I don't manually check it at all, it's much easier to do it with iDrive. I do pay more attention to it in spring and fall, when the seasonal temperature change means I probably have to add air in the fall and bleed air off in the spring.
I don't get the reason for disabling TPMS. If the tire pressures are OK you're never even aware that it's there, and if they do drop enough to give a warning it's something you should want to know. But that's just me.

People drove without it for many many years....I wonder how they did it

[Billfitz]

They either regularly checked their tire pressures or they had premature tire wear, reduced fuel economy and flat tires. Knowing that people are inherently lazy, and that today they're so ignorant of all things mechanical that most don't even own a tire pressure gauge, TPMS were mandated to not only protect them from themselves but to reduce the amount of fuel wasted by riding on underinflated tires.

We 'got along' without seat belts for 60 odd years and air bags for 80 odd years. Do you plan on removing yours?

[RAZERS]

Nope, I like them.
