Hola, does anybody knows where are the most usual and common ground to chasis wires on Q7 2008? Im trying to find a bad ground but I only si 3 ground cables near the ECU, two cables are together on a bolt to the chassis and the third one is alone on a nearby bolt. I see a third bolt but I dont see any ground cable coming out from anywhere .
Is there an important ground near the batterie?.
I still get the errors on ignition on cylinders mostly 1 and 2 but then randomly swaps to others, I tested every single cable for the spark plugs and seem to be fine.
Is there a diagram for the most common and obvious grounds?
