limp mode??

I guess the fact that CRD's monitor flow through the EGR (hence the error code when it's blocked) is what makes them able to compensate the boost correctly and also not hit limp when the EGR is blocked, and would mean their fuel mapping isn't effected by the block. But like ET said that's enough of the gibberish from me as well.

Lemo.

I think it is a hide the symptom versus cure the problem but pffft, both will stop a limp mode.
I guess it is only needed for maf's that have a 'higher' output for a given airflow.

I want more air so my ecu and chip can feed more fuel so i get more herbs.
The maf sensor is saying you are now getting more air so have more fuel.
I modify the signal to say you are getting less air.
The ecu then takes fuel so i get less grunt.

... And to make it more complicated the egr valve control is different between the di and crd
afaik crd's aren't an "open/close" valve, they are a stepper motor.

Anyway, the op has a di so i'll bow out and stop confusing the issue with my crd gibberish. :clownredpuff:

now silence i kill you

I went for a 100 k drive and about 80 k in my bus started experiencing limp mode again, back off the throttle completely and gas back on again it comes right for a bit then goes back to limp, should I have disconnected the battery when I took the blanking out and put the original gasket back in?

Do you have pyro/boost gauges?

No not at present

Hard to say what happening mate. Is it happening under power or cruising? Do you have dawes/needle valve?

they say disconnecting the battery for 20min or more will re set the ECU

No Dawes valve as I've put engine back to stock, it does it when cruising at 100kmh, I had no issues until I cleaned the maf

so cruising at 100 it just goes into limp mode for no reason. I say cruising to

I know its a pain mate but get NADs done, you'll kick yourself for not doing it sooner. Makes the ZD drive heaps better.
