Traced the misfire on 2/4/6 bank as the coil pack has badly split.

In my spares stock have found a brand new Bosch coil pack for 2/4/6 bank although whilst visually its identical cross checking bosch parts catalogue it is for a v6 signum/Vectra.

Will this be ok to use or are they different internally ?

Ok, another useless DBG post that doesn't answer the question directly, but...  I can say that there is zero issue fitting an earlier engines coil pack from a Vectra/Calibra etc to an early Omega (aside from the different plug) - it does the same thing = fires the cylinders in a particular order, that's it. And (of course) same for HTs, mine's running on Vectra HTs as we speak.

So if I owned a 2.6/3.2 and saw on of these, I'd have no issue fitting it; I'd certainly give it a go. Only issue I can imagine is if the actual 'holes' in the rocker covers are a different shape, different plug, or something, hence the part no difference. (but you say they are visually identical, so perhaps that's that out) But in terms of 'voltage/electrickery/keeping ECUs happy' etc, I don't think there's issue there.

Cheers for support DBG.

Just fitted it and all plugs in and seals as it should.Will leave putting the top cable tray cover on for a while just until it fires up and hopefully runs ok then wrestle that back in place without busting any of the stupid little plastic tangs.

Old coil pack had split badly across 2 and 4 so anything will be an improvement though.Expect as engines are identical it was just Boschs way(being German) of making 20 different part numbers for the same thing

Well all runs nicely and no issues so fingers crossed it sorted

The parts are identical except for the number...

That was my conclusion Al as looked identical although Bosch number differed.
Remembered buying it several years ago as old stock for about £20 so rude not too.Just done 50 mile drive and all good.
Will replace the 1/3/5 side at some point as both were originals

Defoaming that corner of the scuttle should see them last indefinitely
