Audi Repair Questions? Ask a Mechanic for Answers ASAP
Hello, I'm Jason. I will do my best to answer your question quickly and accurately using the information you have provided.
ok, so we'll talk about starting and charging systems here....
back about 10 years ago or so, when a battery died or got low, you'd experience some sort of slow cranking situation with the engine, but now....
things are a bit different....
these days, once the battery drops under about 250-300 cold cranking amps, the starter won't even attempt to crank the engine over....
but at 250 amps, the lights will still shine brightly
so you think it IS the battery then?
well, now here's the twist. Your car has two batteries
there is one in the engine compartment for starting only....
and one in the spare tire well for everything else
so it's quite likely that you have a dead starting battery
I recommend testing both
would that cause CD player to activate and clock to reset?
audio system is set to SAT
well, that's why I recommend testing both. The accessory battery might also be low
gotcha. so I have to have someone come and test it, yah?
correct. Load test and alternator output test for both.
each battery should have at least 500cca capacity
alternator output at least 13.5v
but I have a strong suspicion this is your only problem, so not terribly expensive
yeah, just have to find someone to come test and jump, if need be, I guess
AAA might have a service like that, even if you're not a member
but not sure about that at all
gotcha, okay thanks
sure thing. Glad to help
