Sounds like classic coil pack failure. If you can pull the codes it will tell you which one's are shot. At this point you may do well just to replace them all should one or more turn up bad on the codes.

What is the coil pack? Where is it located? How much would it cost to replace?

They are on top of the spark plugs. Not sure about cost but figure about $30 to $40 each....

I just got back from Auto Zone and had them pull the codes from the computer. I got code P0441 VAP system incorrect purge flow, blocked vapor canister. Probable Causes Faulty vent solenoid, Faulty purge solenoid, Faulty fuel tank pressure sensor. P0421 Warm up catalyst efficiency below threshold- bank 1, Air leak before cat converter. Probable causes, Rich Air/Fuel ratio, Faulty Cat Converter.
I looked in the Audi manual as well and it says that if the check engine light comes on and starts blinking the way it is now that it's a faulty cat converter. Also the person that checked the computer said that cylinders 2 and 5 are misfiring.

Based on what you have indicated there are two issues. One is the vapor canister system and the other is running rich and catalytic converter related issues.
Engine mis-fires and bad spark plugs/coil packs will basically send raw gasoline into the exhaust and ultimately damage the converter. I believe that if you fix the mis-fire issues that should help in that regard. A good run at full operating temperatures will also help once you fix that issue. You should not drive the vehicle until this is resolved that is why the engine light is blinking and not just remaining on.
If you fix the mis-fire issues the blinking light should go off but you may still have a solid check engine light due to the evaporator issue. That fix may be made after the fact but if you want to save expensive repairs to the catalytic converter you should fix that mis-fire matter immediately.

You are an idiot ur supposed to change ur timing belts every 60,000 miles you cant
sue that ur own fault thats the problem with this country everbody wants to sue when its there own fault.Audi's are great cars and will last forever as long as u take care of them and do all the scheduled maintenace so good luck trying to sue its right in the handbook about the timing lol !!!!!!!!!!!!!!!!!!!!!!!!!!!!

hi them B5 have the stance of oil cooler gasket (located between the oil filter and crankcase) wearing out after 10yrs(in 08-09); It found a DIY post at the VW passat forums easy fix depending how good you are at tools since a replacement gasket only cost $9.99. good luck and hopefully that's your only source of headache....damn B5s!

Hello audib5: While you do make some valid observations in your rant on daget1, I have to point out that at least in prior years, the Audi manuals that I am familiar with DID spec the timing belt change for 90k (although I can't comment on later models). I was planning to change the belt on my first Audi, a '97 A4 2.8 at 90k until I noted on the forums that many knowledgeable owners opt for 65k or 70k, and IMMEDIATELY had it changed (85k) when I discovered this. I was also surprised to find out that VW changed the 1.8T oil spec from conventional to synthetic AFTER the 2002 model year, and I had already done two oil changes with conventional on my used Passat (prior owner never provided the manual's addendum page, or maybe never received it). I would like to make two points here: 1) There are MANY Audi owners who don't have the level of experience that you and others have, and they should not be faulted or chastized for following what they see in their manual; and 2) automotive forums are, in my opinion, created as a means of sharing extremely valuable information between owners. Yes, I know sometimes commentators are prone to dump on the manufacturer if they have a bad experience, but for the most part, people just want to ask guestions and get answers from those in the know. Therefore, I think you do a disservice by blasting someone who believes they are justified in seeking redress. For all I know, daget1 is a professor of quantum physics at Harvard, but just doesn't know a lot about Audis. It is highly unlikely that he is an idiot, and it only discourages participation when people make comments and get blasted. Thanks! audiphile1

Hi there,
You may not have noticed that you were replying to a post that is almost four years old. I imagine the situation has been resolved one way or another by now.
Let's ease up on the name-calling, okay? You can certainly discuss the fact that changing timing belts and performing other scheduled maintenance are requirements to keep the vehicle running properly, but let's be civil about it.
Thanks!
