Simply take yer motor to the garage
and ask the guy too do a compression test

could be just due to a bad pnumatic lifter

better catch it early and now !!!
before you end up with a bend valve

plugs should be brown look up some pics
can be bad piston rings or an intake valve sticky lifter
watch out this can also be a timing belt issue

Oil leaking into a combustion chamber can foul even new plugs. Pull the plug and have a look at the electrodes

Where is the coil for cylinder 3 on a 2003 audi a4 quattro v6


Each coil pack is located above the spark plug, There are no wires on newer audi's but there are individual coil packs for each cylinder. #3 cylinder coil pack is located right above #3 cylinder. Hope that helps!

2004 Audi A4 misfire


it is always a good idea to stay with o.e.m parts and yes there is updated parts in the newer coils. and yes the M.A.F will also cause misfire faults but will not make check engine light flash or make car shake and shudder. also check you wire harness going to your coils make sure your ground wires are not cracked. That could be the main culprate. good luck hope this helps

Car runs rough when warm an accelerator is applied normal


P0306 is a misfire on cylinder number 6. The fact that you have oil on those plugs may or may not be causing it. The oil on the plugs is because of a leaking "internal" valve cover gasket. First thing I'd do is change the valve cover gaskets. Audi will murder you if you want them to do it (I've heard of people quoted $700 or more for this job). It's VERY easy to do. You can order the gaskets from www.ecstuning.com or www.purems.com for about $25 per side. I'd change them for sure, as they're a known issue on these cars.

Now, if your new plugs and changing the gaskets (and cleaning up of course) doesn't fix the misfire, you need to swap coil packs around and see where the code goes. The coil packs are the three parallel items on the top front center of the engine under the beauty cover. Trace the #6 wire back to see which coil pack it goes to. Then swap that pack with another pack, clear the codes, and fire up the car. See if the check engine light comes back and if so, scan the car to see what codes come up. If you still get P0306, then the failure didn't move, and the coil pack is not the issue (in your case, it's likely to be the wire, since you have new plugs and swapping coils didn't work). If the misfire moved to a different cylinder (one which is now hooked up to the coil pack that was originally firing the #6 cylinder) then that coil pack is bad and must be replaced (another known issue on the A4).

Multiple misfire codes tend to indicate a problem with the coil packs - it's a fairly common problem with the A4, moreso on the 1.8T than the 2.8 V6, but failing coil packs are never a surprise on an A4.

A4 Quattro,misfire detected cyl4.


Coil packs are relatively common failures on the B5 A4, although it's usually on the four-cylinder turbo. Swap the coil pack with another one on the bracket, clear the code, and then run the car and scan for codes. If the code doesn't change, then the problem is plug or wire. If it follows to a new cylinder driven by the same coil that is currently failing at cylinder four, then it's the coil pack.
