Can anyone shed any light or offer some advice if you've time.
In Aus with a 904 Sprinter 612.981.
My turbo boost works much better on a cool morning or evening than in the middle of a hot day, where the boost performance drops off guesstimation of up to 40%
I have a boost guage mounted on the dash.
Ive checked the wires of both boost temp and pressure sensors and all five wires have no earth leaks and have no breaks / open circuits.
The temp sensor resistance is responsive to temperature change (bic lighter) and 5volts at the supply.
The boost sensor has 5 volts at the supply both return variables have voltage fluctuation measured with a digital meter when rpm varies.
Can anyone comment on any possible calibrations / codings for the boost controls including the sensors and or vacuum solenoid.
And if so does one need a trip to a Dealer for their diagnostics gear.
Thanks
