VW T4 1.9 TD Blue Clocks - Oil Pressure Indicator, Warm Engine Pressure Range & Alternator Issues

Hello!

I have a vw t4 1.9 td blue clocks. The car fires at a touch, doesn't kick. Above 2 thousand turns, the oil indicator lights up and squeaks.
So I took off the cover at the bottom, unscrewed the oil sensor in the oil filter and screwed in the hose and pressure gauge. On a warm engine it showed 1.4-1.5 bar.
After adding gas, it increased to about 2 thousand (not max rpm gently).
Is this the correct pressure?

From what I read, these engines have two sensors at the bottom and top. Unfortunately I can not track the second in the head can someone suggest?

The next thing is that I disconnected the plugs from the alternator - I have two plugs, and I washed with the contact and put on since I no longer have the engine speed - tachometer. Charging is around 13.8-14.2 slow.

I would like to suggest more experienced colleagues.

While giving gas at a standstill, the abs light on the gassing lit up - the scanner showed a sensor error on the right front.
Maybe it has to do with the pressure control?
I also had the situation that the car did not react to turning the key - just nothing, I moved the gear lever and the starter came to life - was it possible or a coincidence?

Hello. The correct oil pressure is min 2 bar at 2000 rpm engine temperature 80 ° C, the sensor does not leak? If you install another, ask in the store for Italian. As for the tachometer, remove the plug again, see what the condition of this pin in the alternator and the plug is. Abs has nothing to do with it. Regarding firing, the coincidence probably starts with the problem with the cube under the ignition.

This is not correct but minimal.

Repair the generator harness. This will happen without a tachometer signal.

Please read with understanding, "The correct minimum pressure must be 2 bar,"
