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.

Funny u should say that I've literally just been looking at them! Aha and said they can go too , (another part with a diaphragm)
Yeh seen not costly tbf but as I wouldnt be doing it says its an intake mani off to get to it etc.

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

[Norwichdaz]

Oh really? Says for taking off the intake mani etc is more an advanced diyer apparently lol


How much roughly for a walnut blast?🙂

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.

Ah ok thank u... nice chunk of change then, after a few hundred when pick car up today, mot in January too so will see how that goes too lol..

Yeh do doesnt seem toooo bad tbh...I see some people put a forge on, then lots saying to put original/oem dv...

[Norwichdaz]

Picking it up tomorrow now as bit late and city traffic is a joke lol..

He did say on the phone tho that replacing the pcv today thats there's a hell of a lot more suction on oil cap etc when try take it off..so thats a plus and he says the misfires have gone.

As I said tho not sure if the blow/leak noise when release pedal has gone or not yet tho.

[Nino]

Sounds like I was right about the PCV failing then.

[Norwichdaz]

Yes bud, ill see if the blow sound is still there on decel id imagine it is tbf...then maybe look into DV..

If did do that oem for same or a different dv? I mean its not like it tissssh when changes gear atm, dsg
