    03 GTI 1.8t rough idle (misfire). Multiple DTC's

    Hey guys.

    I've got an issue that developed not long ago. my wife's '03 GTI 1.8T all of a sudden started to run rough (has a misfire). the Check Engine/EPC light is not on. But I did an auto-scan. here are the results...

    I've looked for threads pertaining to similar issues before posting.

    Thanks for any help you guys can offer.

    There may be other things going on here as well, but the very first thing I'd do is put a fuel pump relay in that car, then clear fault codes, drive it, and see what comes back.

    Now I'm not normally an advocate of doing diagnostics by throwing parts at the problem, but a fuel pump relay isn't expensive, it's a common failure item, and when it starts failing, the ECU will set many of the fault codes in your list (particularly the "Short to GND" ones).

    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.

    Change your fuel filter, could be clogged.

    But i think Uwe is on the right track too... fuel relay or fuel pump going.

    if anything else

    When is the last time you replaced timing belt?

    also look for vacuum leak. disconnected/cracked line. (Spray carb cleaner around hoses, throttle body, injectors...see if idle changes.Don't do this with a hot engine....don't need to spray crazy lots either. Keep a fire extinguisher handy incase. )

    Boost leak.

    Also make sure your sparkplugs are tight. I had one sparkplug come loose and it caused misfires.

    DISCLAIMER: All of the foregoing is based on a quick google search, so it may be totally incorrect. Hopefully somebody with more knowledge can offer more reliable info

    Cheers.

    The OXS sensors when taking a shit/short ........also a common brown out, will cause that FP relay to get hot. Cause verse effect!
    If left untreated it wipes the ECU out entirely.

    Thanks for the input guys. I had a hard/no start issue with my 02 VR6 GTI, and it had lots of codes like this. I replaced the fuel pump relay and viola! ...fixed. So the relay was the first thing I replaced on her car, but it made no difference and I thought it might be a MAF, so I tested it and it is good, too. That's when I did the autoscan. I also did a full service including the plugs and fuel filter at 104K miles (the day after we bought this car). The fuel pump is new also. The guage was not reading correctly and I diagnosed it to the fuel level sensor and replaced the pump and sender as one unit (at 108K and with a new gasket). The T-belt and all goodies were replaced just prior to us buying it at 102K (The Previous owner kept great service records and gave us the file). The brake booster vacuum hose does have some cracks in it at the check valve and where it connects to the booster, I did already buy another along with the rubber fuel lines that connect to the fuel rail (they are cracking) at the same time I bought the fuel pump relay. I just haven't installed the hoses yet. I was trying to diagnose this issue first. I didn't want to add too many variables into the mix and spin this way out of control.

    I am not a fan of just throwing parts at it either, but was thinking that I might replace the over pressure sensor in the intercooler and see how that goes. I also have the service manual on CD so I printed the wiring diagram and am going to test the power and ground wires at the ECU and both the Boost sensor and cam sensor as they share power and grounds at the ECU. Any other suggestions?

    Jack, I think you might be confused about which car he's talking about.

    Dimeguy: If you've already put a fuel pump relay in this 1.8T GTI, then the Auto-Scan is indicative of some other source of drop-out of +12V to all the actuators that have "Short to GND" codes.
