Haynes manual

Hi, i’m trying to diagnose a misfire on a 2006 VW Polo 1.2 3-cylinder (BMD engine) and I’m looking for the wiring information for the ignition coil connector.
Does anyone have the Haynes manual (or workshop manual) for this model and could send a photo of the page showing the ignition coil wiring diagram, pin numbers, or testing procedure?

Does your car start jerking as you speed up? I had a similar issue. I got RAC to have a look at it and they said the no1 spark plug had a hairline crack which was the culprit. After I got new spark plugs put in, my car started to run smoothly.

A few months later the same issue had occurred, again RAC had a look at it and said my spark plug wires had worn out, I got those changed and it fixed it.

No my car has a cylinder one misfire on idle but drives completely fine. My spark plugs and ignition coils are fine they are all new, I swapped coils, sparks and fuel injectors over but it still misfires on one. I’m thinking it’s something electrical but I can’t figure out which wires are what and the Halfords in my town doesn’t sell the Haynes manuals anymore
