Hello guys and gals! Under hard accelerating the battery light flashes on/off for a brief moment, typically around 4.5K-5.5K. There is no affect on the power and any electrical systems in the car. Does this sound like the alternator may have had it???? If so will this show up on VAGCOM -which I'm hoping to plug the beast into tomorrow. Isn't there a belt attached to the alt, could this be a little slack/loose???? Many thanks for ideas!
