    Faulty coil or fuel injektor 2.0 tfsi

    Hi!
    Our 2010 A5 888 2.0 tfsi engine just lost power, ESP is on mil on and off.
    Vcds says misfire on cylinder 3 P0303 Misfire Detected
    Engine got no power and got a bad smell and smoke of fuel from the exhaust
    Engine does not start up easy, shakes/does not run smooth, and feels and sounds like one cylinder is dead.
    Strange thing, I cleared the codes just to confirm fault in no 3.
    Now there no codes at all but engine still hard to start, shakes/vibrates, sounds like its only on 3 and there that massive smoke smelling fuel from the exhaust.
    Im thinking more and more in faulty / stuck open injector, but how to confirm if and which one(s)?
    or am i lost/wrong as usual?
    this is Engine scan first time, when there were codes precent

    Pull plugs inspect than do compression check.

    Will do that!
    Is there supposed to be pressure left in the fuel rail some hours after shut down?
    will vcds be able to show me what rail pressure is, and what it's suposed to be?
    I’m thinking “if no pressure until just before engine starts (have to crank it lots of turns now) then I concentrate on injector(s)
    Hopefully I find one cylinder flooded, if I got spark and compression then it must be the injector right?
    I’ve never seen this kind of fuel fog from any exhaust before.
    I and my clothes smelled like I’ve been swimming in fuel!
    Pistons, rods, bearings, chains, tensioners and so only got 1600km (2500miles) on them sins dealer rebuilt engine to cure oil consumption.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    It is seriously advised you get an RTFB and in addition to the aforementioned VCDS video Uwe pointed you too, that actual mechanical tests be done to correlate consistency of OBD tests and for FOD.

    Thanks Uwe and european Jack.
    Now I have a game plan.
    Remove all coils and sparkplugs and inspect.
    Also inspect inside of cylinders (and top of pistons) using my small USB camera.
    If there’s any of what you call FOD inside, or markings, pitching from sutch passing the combustion chamber, I might call it a day and my be trade it as is!
    BUT if nothing is pounded, pitched, lose or otherwise bad inside I will go on checking rail pressure.
    I now know that’s supposed to be done with a “warm” engine, but I don’t think I can stand that much fuel fog fumes 

    hello,i could bet that you have a bad fuel injector valve.....and bad coilpacks as well,VW has really struggled with these injector valves that you will be surprised if you were to key your VIN into ETKA,almost 5 revisions.....it could get worse and dump fuel into combustion chamber thereby causing hydrolock,as some seep into oil pan,try swapping coilpacks to see if misfire vacates.....

    +50 for Fred.......indeed!

    The HPP can also leak raw fuel in sump too causing #3 failure or ultimate engine destruction.

    fuel pressure ok.
    Jack and Fredrik u scare me a bit :-) !
    I looked inside all 4 cylinders, nothing bad.
    Got hands on a used 07K905115F coilpack (same as the others)
    Also changed oil and oilfilter (no fuel smell from old fuel)
    Started engine, little ruff at first (but not as bad as before) after 45-60sek I went normal!
    I have ordered 4 brand new coils.
    QUESTION: can the ignition fault counter be reset?
    Cyl #1&2 has 200 #3 750 #4 500 (not the exact numbers)
    I think: starting from zero (0) is a good idea with the new coilpacks.
    More misfire at #3 after new coilpaks = injector problem

    Coil pack & plugs failure are a result of secondary ignition failure during continued use & while in ultimate misfire & that still is not corrected now huh?

    Symphony of Destruction?

    Please post a new auto-scan........
