    05 Polo 1.4 petrol access to spark plugs etc???

    Hi,
    My other half's polo returned last night making misfire type sounds and having had the engine light on for a hundred miles or so!
    I thought i should take a look at the plugs but am immediately stumped as to how to get underneath the engiine cover. Can someone please give me a few hints before I break anything.
    I have the usual tools.
    I am just about to do a VCDS scan which may tell me something about the fault.
    Thanks for any helpful advice.

    Now done the VCDS scan and this shows the following fault code:

    Address 01: Engine Labels: 036-906-034-APE.lbl
    Part No: 036 906 034 JC
    Component: MARELLI 4TV 6549
    Coding: 00071
    Shop #: WSC 00000
    VCID: 5CBC98B1CC30A69
    WVWZZZ9NZ6Y022248 VWZ7Z0E1355439
    1 Fault Found:
    16687 - Cylinder 3
    P0303 - 35-00 - Misfire Detected
    Readiness: 0000 0000

    Does that tell anything other than misfire, and where?
    Any helpful suggestions will be very welcome.
    Thanks.

    I suggest that you read my thread, it might give you some idea, it is 1.4 bby misfire. to get to the plugs you just pull the cover up, there is a small pipe on right which should be pulled off first. There is nothing to break (that i have found yet).

    Witblitz, thanks for that pointer.
    It certainly seems reasonably likely that my problem is similar and simply needs
    a rather more enthusiastic driving style periodically to let it know who is boss!
    I'll try that and report back tomorrow.

    The engine cover is just held on with clips on the 1.4. Grab it at the front and give it a firm tug upwards and it should pop up. Then do the same with the back.

    You should then be able to see the 4 ignition coil packs which need to be removed to get to the spark plugs themselves. The internet says that there is a special VAG tool to remove them but I find that unplugging them and using a flathead screwdriver to lever them out to be just as good.

    Sounds like you might have a coil pack failure. Quite a common thing to fail on these engines it seems. I used to have one and it blew the top off a coilpack at 70mph on the motorway! Dramatic stuff.

    After clearing the fault code, I took the car for a drive and all is well once more.
    Many thanks for all helpful suggestions.
