I changed the oil and filter in my A6 and now...
Perplexed and dumbfounded.
on, with the ignition in the on-position of course, and measure the voltage across the battery
with a voltmeter or DMM. Is it normal or low?
If it is low, say 7-8 volts, it is a dead battery.
If it is the battery, after replacing it check the charging system.
Thanks!
