Hope I am posting in the right place

Additional bug: on 2001 Agila, 1.2l engine (Z12XE) during diagnostics, indicators are jumping randomly.
It means that the gas indicator jumps to "full" then comes back, temperature indicator jumps to read area, then comes back, RPM indicator jumps to 4000 rpm and comes back. Engine is running, idle, tank is empty, and monitoring thr parameters (actual engine speed, engine temperature, etc) shows no variations.
Also, for the same engine, some of the actuator tests do not work. But I will come back in a few days with some print screens and the complete actuator names (I was not inspired enough to note them down yesterday)
The remarks were checked on 2 cars, and I received feedback from another user about the same issues with the indicators.
