Hi everyone- i'm new to the forum- have gotten lots of useful info for my 2003 golf tdi- recently changed the fuel filter- was a breeze after reading about priming the filter. My question is about my wifes 2010 a3 tdi fuel filter change- I understand it should be primed as well, but do you really need a scan tool to cycle the fuel pump 3-4 times, or can i just start it and raise the rpm as i would in the case of changing the fuel filter on my 2003 tdi- thanks
