Exclamation V40 1.9D 2001 85KW MAF voltages

Hello guys!

After clutch set and flywheel change my car run fine. But I have some hesitation below turbo range (<2000rpm). I checked my MAF with multimeter but don't have reference voltages to compare with.

Can someone with this type of MAF (Siemens 5WK9 632, Volvo p/n: 30887504) send me voltage readings when:
1. Ignition is on (engine not started)
2. Engine idling
3. And voltage at 1000, 1500, 2000, 2500 and 3000 rpm

Thank you

No answer for 3 weeks

I can explain how to do this.
You need multimeter and 5 mins of time.
Place red lead on back of connector on 3rd wire from left and black lead on battery negative and measure dc volt scale.
Expect values between 1-5v.
