Hello,

I have just bought a A5 site unseen at a auction(Copart).

When I got the car I plugged my launch pad and it said knock sensors 1 and 2, ramdom misfires, misfire cylinder 2 and misfire cylinder 1.

I took out the spark plugs and coil packs. Here is the pics of the state they are currently at now.

As you can see cylinder 1 has a bit of oil but I can't understand where it has come from.

Here is a small video to so you can hear what is going on.


If anyone has a idea or some experience with this can you please help me. I am not sure what I am going to do with the car. I would love to keep it but if it still gives me issues I will end up selling it.

Thanks for your time.

I know its a bit late now but did you research anything about this cars knows faults before buy from auction?
I suppose you could swap the plug and coilpack from 1&2 to 3&4 to see if the misfire moves over.

Why does the bottom plug have oil?
