I have a 2006 audi a6 3.2 quattro and once in a while ill go crank the car and it won't start than i try to crank the car immediately after the failed crank and it will crank up. Do anyone know what could be causing this problem?

@Chrisjharris - could be a number of issues: battery, alternator, fuel filter, HPFP, electrical connection, etc...

Just changed the battery and the alternator keeps the battery charged so the alternator is good. what is HPFP?

Based upon your past posts, you seem to have had some some of premature depletion of your batteries. Perhaps you have a parastic power draw. HPFP = High Pressure Fuel Pump. You're best might be to take the vehicle to a mechanic who can ascertain the failure, before you get stranded somewhere.

Thanks the past post ended up being a bad cell in the battery.
