Ebay MAF's: any good?

[Arctic]

I am also considering buying an EGR bypass. It's best to buy the physical bypass item, or just remove the tube and fit a screw on it?

Kind regards

Sometimes look on here I have had a couple of members ask about it, and wanting it but can not get an answer ? postal cost will be a bit more overseas.

Talking about MAFs... I just installed TOAF software and checked the (CDTI) engine live data. It says the required air mass is about 600 and the the real air mass I get is about 500-515. Should I be worried about that even if it does not cause any engine error codes? I changed the air filter and sprayed some cleaning liquid in the MAF but it still shows the same readings. Could that be a reason for the idle vibrations?

I measured also the injectors and they show some -1 to +1 readings on a warm engine. The engine temp was only just over 70 degrees Celsius after a test drive so is it too low?

MAF readings should be between 495 and 505 mg/stroke at idle EGR closed and between 620 and 680mg/stroke at 3000 RPM with the engine off load.

Readings will be accurate at engine temperatures >65 degrees C
