Basically other day car was running fine, i did a oil change and knocked the coilpack plug out. Drove the car then the plug fell out, plugged back in and then it fired up all ok and was running fine.
2 days later, i have management light now, you can feel tiny bit lumpy on idle but idles at 750rpm.
Its no hard to start, asif the battery is flat... takes awhile to turn over, sometimes need to use the gas pedal.
Ive got a OBD2-USB. Ive tried using VAG-Com, but being its not VAG it wont scan the car for codes. Is there any free DECENT software like this i can use in order to check for codes.
Also any ides on the problem at all?
