#1755 of 2367 Audi A4 Engine HELP
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
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.

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.
#1759 of 2367 Keyless entry 2006 A4
Mar 23, 2008 (4:49 pm)
Today my keyless entry system died on my A4. Thought it was my battery so I tried my backup key and THAT didn't work. The small red LED light comes on on both keys when I press it. Could my system be immobilized for some reason?
#1760 of 2367 Gasket leak cost
Mar 23, 2008 (7:01 pm)
My friend's 2001 A4 is leaking oil. She loses a quart of oil in a week. She stopped by a dealership and they said that the gasket is leaking and will cost $1500 to fix (labor and parts). Does that sound reasonable?

"...and they said that the gasket is leaking..."
Ummm, which gasket? The A4 has lots of gaskets, some are a piece of cake to replace, some not so much.

Cold start valve was the culprit on my older Audi.

Ok, she got the car looked at and they said that the main oil leak was from the cam seal and the valve cover gaskets. Additionally, they've suggested a few items that need repair:
valve cover gaskets
cam seal x4
Total cost of $1800 plus tax. Does that sound reasonable?
The water pump, timing belt, tensioners, etc don't need immediate attention, but they suggested that since they're already working on the engine, might as well take care of the other stuff.
