Re: Digital mass air flow sensor

Thanks Steve I will take a recording and post it on here the vehicle in question was a 2012 vw transporter caac engine. However I am struggling on any vag vehicle with digital amm from 2.0tdicr engines to 2.0tfsi. I can manage to get a line plotted in frequency however never goes high enough when re...

Hello guys had the Pico a little while now but seemed to be struggling in converting the digital signal from mass air flow meters into a readable analogue signal. I convert to frequency on the drop down menu from channel letter and it still does not seem as I know it can be done. Any help be much ap...

Vw 2010 passat 2.0tdicr engine low fuel pressure

Hi guys I have a vw passat 2.0tdi cr engine in the workshop which cuts out due to rail pressure dropping too low when coming to a junction or when depressing the clutch and allowing the engine to return to idle. The priming pressure is good (5bar with zero cavitation ) when fault occurs. I am suspec...

Looking at the proof test it seems that fuel pressure is far too low. Has the priming circuit been checked pressure wise?
