Don't buy coils until you check...
the above coils from ecs decent? They are only $80 for a set of 4. I also need to replace the cooling temp sensor. So is the green top the one I should pick up? http://www.ecstuning.com/Audi-B5_A4-...Sensor/ES1484/
Don't buy coils until you check the dealer or stealer however you will have it. I have a 2001 Audi A4 Quattro 1.8 too(looks identical to yours actually). I got a letter about two months ago for a recall on coil packs. I got all four replaced for nothing with a 124,000 miles on her something do do with emissions. When they run your vin # they come up with recall info. I'm willing to bet money your on the list too! Check it out tell'm you got a letter in the mail but you lost it or something sometimes they like to play stupid.
As for spark plugs I replaced mine with these: http://www.blauparts.com/proddetail.asp?prod=NGK7808
Fuel mileage is a little better maybe a mile or two better and she idles a lot soother now too... idk how much that has to do with these plugs specifically b/c the old ones were pretty bad. Anyways by the look of it your cars pretty near the same as mine and they are working great for me and you can't argue with the price.
Goodluck!

This whole paragraph is dubious to me. The oil pressure is regulated at it's output, can't increase because of too much in the pan. Plus, the valve stem seals, oil-control piston rings, and head gasket arn't supplied with pressurized oil anyway, nor the seals for crank or cams. It might well smoke, but probably because the crankcase vent system was getting an oil mist from the crank splash. The crankcase breather pipe that wraps around the back of the head to the turbo area probably is wet with oil, you could check where it connects by the turbo. Next, pull the big hose from the throttle-body. I would expect there is plenty of oily residue in the hose and throttle.
Regarding cylinder #2, if it sparks but is flooded with gas, I would suspect the fuel injector isn't shutting off.

So I think what happened is that the car ran too long after the misfire occurred. Fuel was being pumped into cylinder 2 and was not firing. So that fuel ran down into the oil and made it look like the oil was high. (oil smelled of gas today) I didnt get a chance to look over the car much before my initial post.
Is there a way to test the fuel injector for cylinder 2? Or is this a replace and see if it works kind of option?
If too much fuel washed down into the motor the motor could have major issues within, correct? Could be something wrong within the cylinder?

1. Check ignition power stage N122 output to coil #2 on the 4 wire connector pin #2. There should be a pulsed ground to the coil negative.
2. If no ground pulse is present, check the trigger signals from the Powertrain Control Module (PCM) to the N122 power stage, on the 5 wire side of the N122 power stage, pins #1, #2, #4 and #5. Use a lab scope to check for the signal, with the engine cranking. All 4 signals should look the same.
3. If trigger is present on the 5 wire side and no trigger is present on the 4 wire side, the N122 power stage is faulty and must be replaced (NOTE: ALWAYS replace the coil on the affected cylinder at the same time).

Alright. So after more testing cylinder 2 continues to fill with gas when I turn the motor over. I pulled out the fuel injectors and when i pulled it out the injector in cyl 2 was dripping fuel quite badly. The rest of the injectors were all dry.
So is it safe to say that its the injector flooding the cylinder? I could swap injectors and see if the misfire moves. But I think there is alot of fuel in the oil again because it is constantly dripping into the motor so I dont really want to start it up until I change the oil again but I dont want to change it again until I get this drip stopped.

replacing the fuel injector for this cylinder solved this issue. Car is idling fine now. Once again, the only codes I had for misfires was a 302. the fuel injector was flooding the cylinder..and gas got in the oil. Should be good to go now.
