#1749 of 2367 Serious Engine Problem with 2006 A4 by 225hello

I have had problem after problem with my '06 A4 2.0T quattro with a non-audi extended warranty. I've had an authorized audi mechanic run all my diagnostic tests and twice the computer said it was due to clogged FUEL INJECTORS, they did the service ($385 which was considered wear and tear) and 2 weeks later engine light comes on and ran the test again... now it's an air leak in the INTAKE, another $300 also not covered. I've also had to change the COILS once.
 
On the otherhand, it's handling is great. But the car is for those who don't mind paying $$$ in a few thousand miles. Or maybe I'm one of the 'lucky' and got myself a lemon.
What am I gonna do now??? Im selling this pain in the .... and getting a Nissan 350Z. Good ol' asian import might last me a bit longer.
 
Thank you for listening, I feel much better now

Hey Everyone,
 
Minor issue to report and wanted to see if anyone else has experienced it. I have an 06 A4 2.0T Quattro 6MT, with adaptive xenon headlights. When I turned on my car Friday night and was leaving dinner, I noticed the headlights were flicking on and off as I was backing out of my parking space. This was really prevelant when I was making a U-turn, keeping in mind the car was only running for about a minute and the temperature was about 50+ degrees. Anyone else experience this minor item? I have my lights set to Auto, so the lights are always setting themselves when the car turns on, so not sure if that is the problem.
 
Thanks,
Luke

That's sounds like a headlight relay issue.

Thanks for your feedback. Does that mean there is a possible problem with the wiring?

Luke,
 
I have an '06 2.0T as well that bought in 2005. I only started having a problem with the flickering headlights after some a-holes stole the adaptive headlights and fogs while I was in a wedding rehearsal. Warning: Stay away from Takoma Park, Maryland!!! The flickering was so sporadic that I couldn't nail down a consistent temperature or speed. It would definitely happen on hard accelerations and abrupt braking. Sometimes the headlamps would lockup--the "dip" warning light would come on as well. The dip light is yellow and looks like a headlight with its beams pointed downwards.
 
It turns out that the wiring harness was muffed up and frayed. Also, some of the other modules weren't working properly because they were damaged during the theft. The repair shop at MileOne didn't replace them when my car was in for repairs. Good job! Trust me, record the flickering with a video camera. That's what I did since Audi refused to believe me and warranty the repair unless they saw the flickering firsthand. Good luck proving that in broad daylight!!!!
 
I had to setup my Canon GL2 in manual mode (shutter speed and aperture set by me) mounted on my sturdy Bogen in the backseat to capture the flicker at night. Oh, DO NOT shut off your car if you start experiencing the problem; the car will reset itself and you might not get it to do it again. Murphy's Law is always against us.
 
I still have the "dip" light issue. Ah, can't win them all. I've gotta get a good extended warranty.

No, I meant with the relay itself---unless the wire push-ons that attach to the relay are loose. A relay is nothing more than a big switch. So flickering suggests a switch that can't make up its mind to be on or off.

#1755 of 2367 Audi A4 Engine HELP by carsrart

Mar 19, 2008 (1:11 pm)

My son has a 2001 Audi A4 1.8T with 107000 miles(don't worry I didn't buy it for him). While home working on spring break his car has an engine knocking sound much like I was reading on your site before joining it today. He uses Mobil 1 oil every 2000 miles and had the timing belt replaced at 95000. The engine makes the noise when started and at idle and goes away with increased rpms. My trusted mechanic has dropped the oil pan and inspected the screen filter and found 2 small pea size plastic pieces that look like they've been in there for a while. Also found was a very small 1/32 " rod shaped piece of metal. The timing belt looks ok but feels the cam shaft belt tensioner is broken. There was sludge build up. He wants to replace the oil pump and cam shaft tensioner but is unsure if this is the problem. At $ 1300-1500 to fix I want my kid to spend his money wisely. Thanks, proud Dad Any advice is very much appreciated.

I think the cams run off a chain and yep it sounds like that's what the problem is. These engine are notorious for that, so I think he guess is right. Those sound like tensioner parts to me. The belt tensioner couldn't get into the engine oil---that belt doesn't run in oil, but the cam chain does.

#1757 of 2367 Car does not start by audiman5

Mar 23, 2008 (10:30 am)

I have a 99 A4 6v Quattro. When I run the car for a while, and engine gets hot, if I shut it off, the car won't start again. I need to wait about an hour before I can restart it. My dad tells me it's the fuel pump but I disagree. If the pump malfunctions while hot, then it would shut down on me and turn the car off, but that does not happen. Only When I turn it off, then it's a problem restarting. Need your help.

#1758 of 2367 ck engine light by toolshed1

Mar 23, 2008 (12:50 pm)

I have a 96 Audi A4 2.8L. I have a ck engine light on for a coolant temp sensor. I have replaced the coolant temp sensor and erased the code, well the code came back on, same code for temp sensor so I checked all wiring for temp sensor and wiring seems to be ok. I also noticed that the temp guage takes a while to warm up. I was wondering if a thermostat could cause this code to come on. Please help.
