I want to ask for the W203, can you code options like the AMG menu that shows tire pressure (if factory fitted with TPMS)?

I don't think the W203 has an AMG menu.
The vehicle is equipped with TPMS from the factory or it can be installed via additional coding in the ESP and possibly in the KI.

The Schrader system modification should work for you, you need to google it.

Installing a TPMS system on your W203 will require more than just retrofitting the sensors in your tires. But you will also need an antenna system, as well as a TPMS control unit (if you want to display the pressure in each tire).
The passive TPMS system can be activated via the ABS/ESP module. At least even the early W204 and later models had such a passive system. TPMS sensors are not needed in your car, the pressure is controlled by the ABS system, as a loss of pressure will result in a difference in the rotation speed of the tires.

Continuing with the discussion about activating a real TPMS system with sensors on each wheel, I am only testing it on two wheels of the W203 as I can't test it on all four yet!
If anyone can confirm that the system works with only two pressure sensors, I would appreciate the help.

I don't know of any system that works with less than 4 sensors. It wouldn't make any sense. But maybe Mercedes had a different system before, I'm not exactly sure.
Let's go to WIS to check W211 and W203 again to see if they have TPMS and also the number of sensors (min/max).

The problem with the two sensors was just to confirm that the whole system was working as it should!
The ultimate goal is to install 4 sensors on the wheels, but I won't be able to do that until the end of the year!

Okay, I get it.
You can check the data card if you have RDK or TPMS.
"Simple" pressure control – code 477, TPMS system (with sensors) – code 475. Next come elements A69/1, A69/2, A69/3 and A69/4 - these are four sensors.

Everything is installed as new. Control unit N88 and two sensors, which in DAS already show pressure and temperature, but on the instrument cluster still do not show anything even after several initializations.

So, you have a code 475 in your data card?
