I keep getting these codes on my 1997 A4 1.8t.

P0118
P0300
P0302
P1559
P0301
P0304
P0303

Someone told me it sounds like it's the air flow meter. Does this sound reasonable to you?

 

16502 - Engine Coolant Temp. Sensor (G62): Signal too High
P0118 - 35-10 - - - Intermittent

16684,P0300,Random/Multiple Cylinder Misfire Detected

16685 - Cylinder 1 Misfire Detected
P0301 - 35-10 - - - Intermittent

16686 - Cylinder 2 Misfire Detected
P0302 - 35-10 - - - Intermittent

16688 - Cylinder 4 Misfire Detected
P0304 - 35-10 - - - Intermittent

16687 - Cylinder 3 Misfire Detected
P0303 - 35-10 - - - Intermittent

 

What do you suppose is causing all these codes? I have a new ignition contorl module and new coolant temp sensor. I have disconnected the battery and let it sit all day disconnected. The light usually comes on as soon as I start it up.

 

coil packs

 

Sorry to hijack, but how can you tell if the coil packs are playing up on the 1.8t engine?

 

car shudders, misfires, and a blinking CEL

 

SO far, the answers I've gotten tell me. Air flow meter, camshaft position sensor, coil packs, plugs. It seems unlikely that the coil packs would all go bad at once doesn't it?

BTW, this car is running fine. The CEL is on, but, not blinking.

 

I'm not sure, cause i have a differnet engine, but I thought it was one unit. And normally when they go, all cylinders misfire.

 

Thanks mate.

 

Nah there are four coil packs one for each cylinder.
