judder/misfire?
« on: 28 August 2009, 17:15 »
driver home today up the motorway and when accelerating gradually at 60 - 70mph the car seemed to misfire/give a quick judder. now this happened in both 4th & 5th gear. I am unsure what might have caused it, had no engine management light come up.

Is it a possibility a coil pack may be on its way out? My car is a 00 reg AGU GTI Turbo.

Suggestions/opinions appreciated.

coil packs are a rarity on AGUs compared to AUM/AUQs, usually the ignition amp or like Topher said the MAF

Although there are no MIL lights on get it on VAG COM as MAF faults don't show up on the MIL.

mine did this when i first got it, was almost as if it was cutting out the engine and bump starting itself all within a split second, and always under acceleration! not done it for a while though.

car has been fully serviced within the last 1000 miles, so plugs, oil, filter, air filter all good.

not sure on coilpack as it only does it every now and again. Think i may try cleaning the MAF n go from there.
