Hello everyone,

I'm seeking advice about a fault before I start this time Wink

I have a problem with car above. The customer said that it just started running rough and wouldn't pull above 40mph tonight, at the same time the MIL came on.

I have scanned the car and it has fault code P0303 stored, (Cylinder 3-misfire detected). Ok so we know the fault and location. Are coil packs a problem on this engine or am I barking completely up the wrong treeHehe  Also if it is the coil packs, how do I get to them without breaking anything?

Thanks as always for your advice

Lee

Kev,

Sorry no engine code, but it was dark. I gave as much as I could, as it saysBigGrin

Aiden,

Is it just a look at the insulation or is there a better way to test it?

Kev,

I just found an engine code on AD, it is AWT and is the only one for that year and engine.

Lee, would be worth checking the plugs for a start.

Try swapping No 3 Coil to another cylinder, see if the misfire moves with it.Cool

Hi Chris,

I had thought of that but wasn't too sure if it would cause any damage to anything else, but now you've said it as well I'll try it in the morning

I had a quick look at the tops of the coils tonight, but I couldn't see any obvious mounting for them. Do they just lever out gently? Unsure

60k, is that it Crazy I always thought these engines were bullet proof. A colleague of mine had his cambelt go at 115k on his TT. The Audi technician said he'd had some sort of catastrophic internal failure, then charged him almost £7000 to fix the carw00tw00tw00t
