VW Touran 1.6 TDI CAYC Injectors

I've spoken to my local garage, they're going to give me a quote for the repair work. I'd rather just do it my self though, might just bite the bullet. Can't see the point in just doing 1 but we'll see.

Including VAT that is OK.

Car parts 4 less with discount is £251

[Crasher]

Although you have to factor in the complication of returning the old injectors and getting your surcharge refunded, that is a good price that to be honest ECP should not offer to the public, it is unfair on their trade customers who only pay £10 less.

[audileon]

There's no mention of a surcharge weirdly.

[Crasher]

They don't on their trade site either but we have had a few recently and they wanted the old ones back.

I serviced the car on Saturday, fresh fuel filter. Got the car lovely and warm and got the following readings.

I never actually got round to doing anything about this. The car has gotten gradually worse and worse on idle, it just hunts all the time.
When I posted these a few years back (baring in ,mind I've done nothing with it, it was suggesting 3 and 4 were on their way out. Yet recent scans suggest 1 and 2 may be worst. Are these deviations actually anything to be bothered about? Could the rough idle be something else?
