how bad is this?.....codes inside
 

Hi guys,

My car is a 2000 a4 1.8t quattro and currently is sitting at 180,000 kms. I was driving it recently when all of a sudden it started to hesitate pretty bad and almost stall out, I pulled over to the side of the road and noticed a slight knocking sound so I shut her down and had it towed to a dealership. They think it is a can tensioner that has given out, but couldn't pull the codes till i disconnected my aftermarket cd player........

Here are the codes I pulled:
16687-misfire cyl #3
16688-misfire cyl#4
16685-misfire cyl#1
16686-misfire cyl#2
16684-misfire any cyl
18010-power supply low
17522(?)......my code book doesnt even show this :S

Any idea on what could be the cause of this and really how bad is it?

Thanks, JC

18010-power supply low battery disconnected or drained
17522(?)......my code book doesn't even show this :S o2 sensor resistance too high bank 1 sensor 2 wiring short to ground battery being disconnected or drained while engine running would cause all that

Change the spark plugs, reset the codes and see if they return.

doubt all the plugs took a dump at the same time... try to see which cylinders have a dead misfire not sporadic, swap the coils, plugs,injectors, etc from the known good cylinders and see if the misfire moves. if all the cylinders are constantly misfiring replace your ignition control module on the airbox.
