Chasing down fairly severe battery drains on this 7L/T1 Touareg. This battery would be killed in a day or two and the battery tested out okay yet. Started out with an intermittent 2.5A draw, dropping to a 400mA, then with a little more work dropped to a 100mA. Its still a higher then VW spec of 40-50mA but with these large batteries it should be good for a few weeks of sitting.
