Mk5 misfire

[mozgame]

The first time this happened (2 months ago) WAG diagnostic tool logged misfire on cylinder #2 and a simple coil pack replacement fixed the issue.

Two months down the line and the car starts misfiring again. This time though the computer/WAG doesn’t pick up anything :wtf:

The mechanic can’t see anything wrong with the coils _ the vehicle still in for further diagnostics…

If anyone could shed a light would be much appreciated…

Don't lauf but i thought you was talking about a gun when i saw the title, am sure someone with this knowledge will be able to shed some light, hang in there

how much mileage does it have ?

When does this happen, cold starts, running etc?

Check HT leads, plugs, injectors, inlet manifold gasket for air leak & carbon build up.

Check the coils packs again by swapping them around and see if the misfire follows the coil pack.Maybe look at changing your plug type & brand.

Heh, I thought a missile was misfired or something.

Yes there are different revision coil packs.
