I just rang him and said to replace the pcv valve aswell he said it only had a little suction tbf so for that and piece of mind getting a new one.

So that will be new plugs, new pcv and I said to replace all coil packs too.

He did mention with how that cylinder 2 was dirty he mentioned poss valve may need cleaning (walnut)

Yeah they are known for this, its because they are direct injection.

 A walnut blast is the only fix.

One other thing I forgot to mention is the Diverter Valve (Also known as dump valve). I remember that certain revisions were known to fail I cannot remember for the life of me which part number is the latest ones. But they are relitively cheap so might be worth having that replaced too, MAKE SURE you only use OE parts unless its forge.

The Diverter Valve you should be able to do yourself, the Walnut blasting, I would find a repitable place to do that for you.

Have a watch of this, the DV is located under the car on the side of the block, you will need to jack the car up and remove your arch liner and under tray to access it.

Held in by 3 bolts and 1 eletronic clip to remove.

I beleive this is the one you would need revision D but double check before buying.

As for a price of Walnut blasting, it will vary based on your location and who you use. I'd expect at least £500ish to have it all done properly.
