So I have just realised, that instead of having a temperature sensor for the ECM - blue with two pins - part number: 025906041A
Someone have fitted a identical LOOKING thermo switch, part number: 021919369
After finding open circuit - I fitted TWO Hella sensors.
Both are toast. I hope I havent killed the VAG original sensor.
So - checked voltage to the sensor.........
We are at least two people with exact same fault code (on pre cat lambda sensor electric circuite - P0130 as well as cyl. 4 missfire - P0304) who also have constant 12.8V to the sensor - with ignition off. And with engine running: +14V.
Yes - we both had exactly 12.8V.
I havent heard from the third guy with same issues, yet, but his temp. sensor is killed the same maner.
This must have happened more than us.
Some bright person, have gone to the scrap yard and found the thermo switch, fitted on a 6 cylinder petrol engine, that runs the coolant fan! " Hey! It looks the same - lets put it in my car!"

In the end I opened both the originally fitted switch and one of the new Hellas.....
The thermo switch:

The Hella temp. sensor - may I tell, it smells crazy BAAAAD:

Now I need to find someone who can fix the ECM - in Sweden or Europe.......

HAHA:
The correct G62 on these cars is the sensor under the blue one.
Its green with four pins.
The blue is for the extra coolant PUMP under the radiator.
Bloody ElsaWin - says the G62 is blue, two pin...
And the four pin sensor would have the thermo switch for extra coolant pump and gauge sensor.....
That is not correct.
The blue two pin switch is for the extra pump (F95) part number: 021919369
G62 and G2 is the the green four pin sensor under the blue switch - part number: 059919501A
