ur s6 missfire coils i think

[220bhp]

My ur s6 has developed a perminant misfire on cylinder 5, the one at the back of the engine.
I have swopped over the injectors and plugs ,and its still the same. Also checked the compression which is fine,
So am I right in assuming its the coil. if so how hard is it to replace.
Is it plug and play or solder.
I am looking for a spare coil if anyone has one for sale.

You'll have to solder it in. It could also be a pos gone awry. There is stuff on this within the forum about swapping to the spare pin on the pos.Might be worth doing that first before installing a new coil.

You will want to read through this (and its hyperlinks) before you get out the soldering iron.
