So my Passat had several ECU flashes several years back to correct glow plug issues. The went from a 7v plug, to a 5v plug, then back to a 7v plug. Each needing a flash to reconfigure the voltage.
Is there a visible version number that I can see with a VAG COM? And if so, how would I figure out if I have the latest flash?
I just want to be sure that I have the latest 7v flash, and not the older 5v one.
