Audi A6 4.2 V8 Quattro 2002. Diagnostic code P0492 - Faulty air solenoid valve and air system relay.
What is the repair cost to fix the problem? Vehicle hesitates and ******" before slowly accelerating after coming out of a stop. Full pressure on gas throttle with delayed weak response. Problem is worse going uphill.
