Audi 2011 Q7 3.0 TDi, intermittent battery drain.
Client states battery was replaced 1 year ago at a neighbors shop, Delco.
I do not believe it was coded. He said that it had been fine up til a few weeks ago, shortly after he had the blower replaced.
Tipped the drivers seat back and hooked up an amp meter. With the doors open the initial draw was 410 ma (.4 amp). After 2 min it spiked to 6.0 amps for about a minute and a half, then went down to 410 ma for 5 min. Then spiked to 6 amp for another min 30sec, then back down to 410 ma for about 30 min. Finally settled at that point to 60ma (.060 amp) and stayed there. I don’t think 60ma is going kill a good 900 CCA battery with a 150 RC overnight
My questions: Is a 60 mA draw normal for this SUV?
Is there a common intermittent fault for draws?
Thanks a bunch guys.
