The rear sensor is okay ,very nice curves on my scope and similar voltage as my right front sensor.

I was wrong about my EHA values.
The fuel cut off function works when the car is cold.
When engine temperature gets higher and the KE is going to closed loop mode then my fuel cut off function fails.
Fuel cut off is easy to monitor and feel when you have manual transmission.

When the engine is cold the ABS and EHA is okay ,but when the engine is hot then my problem begins.
The problem is probably a combination of a bad OVP or the harness to or from it.
When the engine is running and twist the relay around with the cables i can hear the engine not running as smooth as it should.
The OVP fuses voltage is 13.45 volts when engine is running so i guess the power to the relay is okay.
OVP relays are overpriced in my country.
I am also going to check my front left wheel bearing as i think this can trigger a fault especially when the left front sensor signal i weaker.

I am going to testdrive the E400CDI and feel if that could be my next car.
