ColorMFA

The TFSI engines have a fuel pressure sensor inside. You could use that. But as you already wrote, unfortunately I only have an analog output signal that is processed in the engine control unit. Unfortunately, my engine control unit cannot do this. But I'm at least glad that the tire pressure control works perfectly in your system. You can not have everything.

The sensor also withstands oil pressure, I tested it

I know about the fuel pressure sensor on the TFSI. But there is still nowhere to connect it in ColorMFA.
You can make your own device that will transmit data from these sensors to the CAN bus. See above for information on what data ColorMFA understands on CAN-bus.

Hi regarding the low oil level message does the car actually need to be started and running for the low oil level meassge to come on.. or should it come on even if just the ignition is switched on.. I drained my my oil for service and thought I check and see if low oil level comes on.. but it didn't..

How does the low oil level and low oil pressure warnings work in the original system:
- low oil pressure. The engine must be started, the revolutions must be above 1200-1700 (depending on the engine and the sensor installed in the car).
- low oil level. After each opening of the hood, the car must travel 100 km, the system must receive 5000-7000 sensor measurements under certain conditions (oil temperature must be above 40-60 C, acceleration and lateral displacement of the vehicle must be within certain limits, engine rpm must be within a certain range, etc.). The exact parameters vary depending on the engine.

ColorMFA works the same as the original system. But the conditions are a little simpler (for example, sometimes it is enough to drive 50 km instead of 100 km).

Hi I did the latest firmware update all I's good I like the new background and reflection option.. the oil level measurement is show max nw and before the update it was showing 1 level below max.. ?

There may have been adjustments to the oil level display. I don't know what kind of car you have and what firmware was installed before the update. So I can't say for sure. But if you saw changes, it means there were adjustments to your car.

Hi before was b40 firmware.. and nw b43 firmware my car is 2003 VW GOLF R32.. also I wanted to ask if the car is started but not driving and on level ground.. should both left and right oil level measurements be same levels..

See pic

left value: current sensor measurement.
right value: calculated value under different engine operating conditions..
These data will not match. If only because the left column at a really low oil level will not necessarily show the minimum. The minimum value is different for different engines. And VAG does not regulate the minimum value when the engine is turned off or when the car is standing still (even when engine is running).
The left column may coincide with the right if you try to calibrate the displayed data (there are such parameters in the hidden menu for the left column). However, this does not work with all engines. On some engines, the oil level value measured by the sensor may not change when the car is standing still at idle (or when the engine is not running). On such motors, the difference between maximum and minimum can be only 2-3mm under these conditions.
