Now that I finally have the new Lambda in it, he's been bitching around somewhere else...
When I was driving away in the morning, everything was still going in AI, after 10 minutes of driving I looked at the temperature indicator (cooling water) and look there, still showed cold, looked at the tank clock, LEER (but only at the indicator)
).All right, looking at the on-board computer, he also suddenly showed nothing, I mean the "screen" was illuminated, but no numbers in it.
I once pushed up the on-board computer and there was something there again, but I couldn't switch between the individual options of the display anymore...
Has anyone ever had such incidents, or have you? Does anyone know what can be the cause of the error?

By the way, where are the oil pressures going? Idle 2bar and 5bar (at me) while driving.
I hope you can help me,
