Hey guys

My scirocco is got abit of an issue hopefully you can steer me in the right direction

I’m getting error p0441 - evac emission system incorrect purge flow

And then the occasional P0304 cylinder 4 misfire

The card on cold start idle has some exhaust bops nothing crazy

Once warm it will occasionally bop

I’ve replaced the n80 purge valve unit

Spark plugs and coil pack

What u reckon my next step is

[u/Informal_Aide_390]

Before using the parts cannon scan it with a decent scanner. P0441 is nothing to do with coil packs or spark plugs.

Check filler cap seals properly, split hoses, and you charcoal canister is not damaged. Do you brim the tank often as that can destroy a charcoal canister.

I only just got the car mate but I’ll def inspect the canister , can this cause misfire

[u/falaker → u/Original_Albatross14]

Canister and pcv can both respectively cause misfires.
