2004 S4 4.2 V8 Cylinder numbering

[rj1983]

Can someone give me an idea of the numbering on the S4's 4.2 V8 - I have a misfire on cylinder 1 and have bought a coil pack to replace. As I understand it:


8 - 4
7 - 3
6 - 2
5 - 1

BUMPER

Tried googling it but seemed to get conflicting results!!!

Ta!

I thought number one was the right hand bank (the drivers side of the car one nearest the bumper)

If you cant be sure which cylinder it is, you can simply unplug, or remove, each coil (one at a time) in turn, when you unplug a good coil, the engine will sound significantly worse + more juddering. When you unplug a faulty coil there is no change in the engine note or smoothness, until you replace it then it will be fine.

I'm assuming the misfire is constant not intermittent to do this test.

I know that a lot of V8's are...

8 - 7
6 - 5
4 - 3
2 - 1

Bumper.

But I'm not sure of the Audi, but lets face it, number one is going to be one of the corners, so try them first.
