Edition 30, all of a sudden lost power. Idle is a bit lumpy.

<< < (2/2)

Northern_ED30:
Changed all those and still got the issue,

This is a video of me with my foot down and you can see it revs all the way…

There’s also a weird cracking sound around 5k..

It’s going in on Tuesday for a service so I’ll get all spark plugs and I’ll get new coil packs then get him to smoke test / diagnose

Northern_ED30:
Update for the forums future reference.

Coil Pack 1 seized & spark plug burnt out.

Inlet manifold had a slight crack (causing initial boost leak which I'd had for a couple months)
Inlet manifold flaps collapsed and came loose, could've easily ended up in the cylinder or got jammed under the valves, so I'm considering my self lucky.

Northern_ED30:
Changed n75 to no improvement.

pudding:
Yeah the crackling at 5K sounds like bad boost control to me, which could be the N75 as you've done.

Ideally, you need that ol' VCDS bad boy to data log a journey and then upload the csv file to the forum so us nerds can analyse it for you.\

The misfiring at idle sounds like classic goosed injectors, or one or 2 of them at least.

Have you done a compression test on it?
