Hi guys - looking for help on how Audi numbers its cylinders.
I have a misfire & think its down to a coil pack (it was last time!) - as such rather than shipping it off i would rather do the seemingly simple swapout myself.
However - can't work out which cylinder is which! I *think* its like this but could do with someone correcting me!

Any help appreciated - google, so far, isn't my friend.

Actually - thinking it through i think i've screwed this up & its actually the opposite of what i've said.
10 is 1 & 1 is 10 etc.

For VAG looking at the engine left bank is 1-x front to back, right bank is x+1 - y front to back, where y is the number of cylinders.
Great - thats where i got to! Cheers.

Nothing is ever easy.

So despite having a fault light on the dash the code reader i purchased stated there were no codes. banghead

Borrowed a mates and it said 4 different coils were screwed - so i thought it had potentially started in one location then caused sync issues in the others.

Bright idea as the car stillrunning rough - kill the codes drive it and see what comes back.

Killed codes - issue disappears and car drives fine...

Lose rag. Drive home as know there is something wrong even if car is denying it.

Drive it this morning and it starts rough - produces an temporary mgt , then sorts itself out, drop it into garage to see what those codes were (as my mates code reader now stopped connecting!) - the new codes state low fuel flow. Only had the fuel filter replaced a few weeks back.

Will leave it till i get a permanant read/fault again. banghead

4 coils were they all on the same bank?
Nope - both sides.

Right - cylinder 3 fault code.
Replaced the coil.
Currently looking ok - thought i felt some hesitation on one full chat acceleration but may have just been the road.
Fingers crossed.

Thanks all for your help.

Not fixed.
Think its a leaking gasket letting oil on the coil when removed.
Getting this done by a local specialist next week.
