I recently cleaned the fuel injectors on my 2009 Q7 TDI. I did the passenger bank first, then started the car to see how things went. It ran pretty rough. I, then, did the driver side and tried starting it...it wouldn't start. Would crank, but no ignition. I put the injectors back in their original cylinders, and primed the pump/system via VCDS 3-4 times after each reassembly. Do I need to reset the injectors as you would when installing new ones using VCDS (http://wiki.ross-tech.com/wiki/inde...9_and_Injector_Voltage_Adjustment_.28ISA.29)?
Both the rear and secondary pumps sound like and appear to be functioning normally - there is fuel pressure build-up during the forced priming.
