im having problems with my 98 AUDI A4 AEB TIPTRONIC with about 140000Miles. I have a blinking CEL and i replaced all four coilpacks (meyle) and sparkplugs just yesterday and i thought it would remove the CEL ,but i still have the blinking CEL. By the way when i removed the old sparkplugs there was oil on sparkplug #1,3,4. here are some photos below. This Saturday I will replace my cat converter ( i already replaced both of the o2 sensors)and fuel filter (havent change it since i got the car which was about 1.5 years ago)...hopefully that will help.

here are the codes i got from autozone.
P1300
P0422
PO203

Is that clean plug from cylinder 3? Check that injector connector. Clear the codes and report back. Did you change your ignition control module?

That clean plug is fr cylinder two. And I change my ICM about less than 5000 miles ago...

maybe your spark plug seals are going / gone?

spark plug seal?!!? really? like mentioned check the injector on cyl #2. the plugs dont look that bad for being used. however one clean one is not right,

Well, if you've got oil on the ceramic parts of the spark plugs, then you'll need new valve cover gaskets.
If the oil is below the "nut", then you've got some internal leaks causing oil to get into the combustion chamber.

I already changed my valve gasket about 3000 miles ago, so im guessin its internal...which is not good! by the way whats an average price to replace the head gasket or whatever?

i guess it wudn't hurt to check. when mine went, i didn't have nearly as much oil on my plugs as you do.

its not the valve cover gasket. there would be oil on the ceramics of the plugs. That plug looks brand new. If the cylinder was firing that electrode would have turned greyish. Check the coil packs again and the ICM as well as the injector connector and the injector itself.

yea its not the VC gasket. if the white ceramic part of the plugs were black, it would be this gasket. its obviously not that. are you sure that its oil and not just unburned fuel?

P0203 - bad injector, connector, or circuit
P0422 - Main catalyst effinciency below threshold (bank 1)....probably from running rich
P1300 - random misfires....probably due to the injector not spraying fuel. Swap in new plugs and move that cylinder 2 injector and see if that clean plug follows it. If it doesn't then check the injector wiring.

Well do you have a better opinion vs reiterating what we see in the picture?

Your ICM is bad again. Swap it with a good one and recheck.

so whats the situation`??
it really seems that bad is something with the fuel mixture.
meaning pull out the injector on that cilinder and check it.
also the ICM... but if it's said to be new already, hmm. sounds more like the injector.

how do you check if the injector is bad or not when i take it out

Poopie

swap the injector somewhere else. and see if that clean plug moves with the injector.

why would 1 injector make 3 plugs foul? is the misfire/flashing cel fixed yet? if not, you should check your faults before you start pulling parts.

as far as testing/inspecting the injectors, you can get some glass or sturdy plastic cups, pull the whole rail with injectors attached, put a cup on each injector, and crank the engine, to compare the amount of fuel flow from each injector. a noid light can be used to check duty cycles, but you really need to hook it up to a vag-com before getting into the heavy technical aspect.

update:
i switched around injector #3 with #4 to see if inj.#4 would spit out fuel...after running the car for about 15 minutes...inj. #4 did not do anything...so im guessing its not the injectors, its a circuit/wire harness and maybe the icm...what do you guys think?

Have you cleaned the PCV system, or replaced the valve anytime in the last 10-11Y? The B6 is notorious for this (so I wonder about the B5), and dumps oil under the cover all over the coil packs, plugs, and harnesses, causing misfires. Fix the PCV system while you're at it.

Update:
Purchased HUCO ICM from Ecstuning...and it got rid of the blinking CEL! yay! haha, unfortunately i still have a CEL...here are the codes

P1300
P1545
P0301
P0300
P0422

Oh so far i got new Coilpacks, new plugs gapped at 28, new ICM, new fuel filter, new o2 sensors top and buttom(less than 300 miles on em)....Any suggestions?

yeah doesn't hurt to change the gasket again even if you did it recently you might of not torqued it down all the way
