Question Answered: Engine sluggish in morning - need octane upgrade?
November 22, 2009, 12:56 PM
cheap gas usually does not contain much detergent and may have too much ethanol. both can cause power loss due to mixture and deposit problems. do not use dry gas (more ethanol) but do use some type of fuel system cleaner (techron or the stuff audi sells).
Question Answered: cam tensioner
November 22, 2009, 12:50 PM
There is a cam tensioner as well as belt tensioner. the cam tensioner is hydraulic and operates by oil pressure. have the pressure checked since oil sludge and pressure loss is common when synthetic oil is not used. left unchecked this can cost you a motor. doing a t-belt should not create a cam tensioner problem. are you sure the noise is from the back of motor, not t-belt area?

Question Answered: Can I relace a Xenon headlamp in my S4 on my own?
November 06, 2009, 07:17 PM
yes, there are 4 #30 torx screws that hold the headlight in. the 2 on top get removed, the lower rear ones just loosened. pull the headlight forward and open the door, 1/4 twist the red/black connector to get to the bulb. HI VOLTAGE!!! DO NOT HAVE THE LIGHTS ON WITH CONNECTOR LOOSE!!!!
Question Answered: Exhaust repair

intake or exhaust manifold? why is it an issue? if your car is a wagon, is it because of an EGR fault? that is usually just removal to clean the intake. is it a secondary air fault? that is exhaust and harder to clean. is it an exhaust leak? try 1800vwparts for good used audi/vw parts.

Question Answered: Parking Brake Service Indicator On- Cannot Disengage Brake
November 06, 2009, 06:52 PM
your park brake is electronic. there is no lever to disassemble. it is possible to reverse the power on the e-brake motors at the rear calipers to back them off but someone who understands that system should be the one to try.

could be a stuck motor or flap. the system is diagnosable with a tester. check for fault codes.
Question Answered: power steering pump noise
November 05, 2009, 07:05 PM
make sure the noise is accessory driven by running the car without the serp belt. does it change when turning the wheel? the water pump is right below the p/s and the a/c and tensioner a little lower.

most MIL lights dont go off so quickly, would love to know what code is stored. if its a coolant temp sensor, check with audi. it may be covered under an extended emissions coverage.
