1997-1999 audi a8 quattro
4.2 iat sensor

took car for a drive. everything worked fine. made a pit stop. cut car off & left for approx 15 mins. returned to vehicle & car started fine. mmi started but no sound no matter the selection. pulled over after driving for approx 5 mins. shut engine off and restarted hoping that would fix the issue. now mmi screen does not boot. just a blank screen. initiated the mmi reboot process. screen attempted to boot but failed. also while driving there is a clicking noise coming from the trunk. the noise only occurs when i press any buttons related to the mmi. before that day these issues never occurred. a few days later i go out to the car in the morning and realize the car wont start. an assisted jump was needed. i assumed it may have been the battery but when i went to have it replaced i had a test run on it and learned that the battery was good. i fear that it may be the alternator. i am baffled as to how an alternator could be failing on a 6yr old vehicle.

It sparked when replacing lights flashed for a split second and then nothing worked

Filter is in a permanent housing; not a removable canister. Cap that secures and seals filter in place does not have enough clearance to get past alternator to allow removal of filter.

no clicking, no lights, nothing. any ideas?

lights on control panel will not light up; thinking it may be a fuse. can't operate radio, cd, navigator, etc.

it is a P reg a8 quattro 4.2 V8 with a 4 speed auto. any help would be appriciated.

when I push the round button in the center to select language and radio or cd; it doesn't do anything...none of the buttons do anything. can I take the console cover off?

is a round or flat filter? I see the air box I believe right there on passenger side.

occasionally its fine. now it will hardly stay running. acts like its not getting gas ??? help!!!!

When I press the dashboard button for the rear defroster, the light comes on and, the outside mirror defrosters, which are also controlled by the same switch, begin to defrost. I have no indication the rear window defroster is working no matter how long I wait. I don't see a fuse specified in the owners manual. Can anyone help me with this? The window grid appears to be intact.

I changed brakes front and rear, new pads and rotors, pads had new sensors in them. I reset rear e brake with scan tool and everything works fine, but the brake warning light is still on.

Can not get anything to blow out of the vent's, It sounds like it's on but nothing comes out

i checked the fuse in the trunk it's not blown. what would my next step be to check out?

I got both lights on the green n yellow but the green goes off the yellow stays on n it air low

while driving at normal highway speed, if I "stomp" hard on the gas pedal the engine will sometimes hesitate or sputter before downshifting, or seemingly lag before firing up to speed

To change the timingbelt and water pump and also change rear brake?

The MMI has been replaced. The dealer says that the instrument cluster must be replaced ($1500). Does the cluster really need to be replaced?

and rear of center console

my temperature is reading celisus and i want to change it to farenhite

passenger side on a 1997 Audi A8 quattro, Do you have to replace the Harmonic Balancer. And when removing the center crank bolt, should it be replaced with a new one. And if not properly torque to factory spec. 285lbs. Can it cause severe damage to the timing belt crank gear and pulley, and also the housing for the seal carrier. And can it cause possible damage to the crankshaft, and damage to the valves which may result in the need of a replacement engine. This question is in regards to my is for my 1997 Audi A8 Quattro. Thank you. my E-mail is darrindss@sbcglobal.net

Want to find out the time intervals for changing the timing belt on my 2004 Audi A 8.

Do you put the refrigerant on the high side or low side. Or can you provide a diagram?


My 1997 Audi Quattro went into "safe mode" with all the gears selected and lit up in red on the dash that normally indicates what gear the car is in? No power, but driveable?

It Makes a Noise when turning sharp, sometimes when I stop to back into a parking space, but otherwise I have no problems.

Just purchased a Audi A8 Quattro and after driving for a while, a loud smell of fuel appears in the passenger compartment, anybody familiar with this problem
