D4 TDV6 3 Litre - MAF Sensor values?

[LRHybrid100]

Hi All,

MY10 D4 TDV6 3 Litre using my IID Tool - what should the MAF Sensor values look like in the live data?

I'm having some restricted performance issues and trying to eliminate the MAF Sensors.

Cheers

There's two MAFs, bank 2 has the primary turbo, bank 1 has the secondary.

If you leave the engine idling for a while, the 2nd turbo will kick in until you touch the throttle again, I don't remember the reason why but it's normal.

Typical MAF values at idle with AC on;

Cold start, primary turbo only
Bank 2 ~23g/s
Bank 1 zero

Warmed up, primary turbo only
Bank 2 ~15g/s
Bank 1 zero

Warmed up, with 2nd turbo active
Bank 2 ~10g/s
Bank 1 ~8g/s

MAF rates while driving are hard to quantify but the idle rates should be pretty consistent.

Thanks mate!

I'll have another look this weekend.
