    USP Motorsports sell a relatively cheap DIY kit,but the real deal is having it properly done,and I believe for around £200 or less.

    Anyone know of anyone in the Southampton area that offers the de-coke service? What's the proper terminology for this service anyway?
    I'm pretty sure my PCV has gone as well, so I might replace that at the same time. Although, I could probably do that myself.

    If you're talking about their intake valve cleaning product,it's something that needs to be injected into the intake,after the MAF,and is supposed to break up carbon deposits on the valves.
    Personally,I have no knowledge of the product,and there's very little in the way of feedback on the net,but I can't see how a spray is going to deal with hard,burnt-in deposits on the valves.

    The other product they have is introduced via the injectors,and won't work on direct injection systems.

    I know which I'm happy with.

    I've read else where that it's a good idea to replace the N80 Evaporative Emissions Control Valve as well. Do you guys agree? If so, anyone got the part number for the latest compatible revision?

    just my humble opinion but if you want your carbon gone there is only one effective way of doing it...elbow grease every 20K for me

    Well just in case anyone else is facing the same issue...

    I replaced my Positive Crankcase Ventilation (PVC) valve tonight, which not only resolved an issue where the car was idling rough at 800-900RPM and hunting up to around 1300RPM, but it restored a fair bit of boost, improved engine response and smoothed out performance when letting my foot off the throttle. Very happy indeed. Especially as it was a five minute job for anyone who can turn a screwdriver!

    So anyways, the handy info I have are the current part numbers, as supplied to me by Southampton TPS (a.k.a The Trade Parts Specialists). These guys are the most professional supplier of OEM parts I've dealt with. Many of the garages/workshops in Southampton get their parts from these guys. That's how I found out about them. Anyway, enough friendly promotion. Here are those part numbers:

    PCV valve cover assembly: 06F 129 101 P = £32.24 inc VAT

    PCV valve cover gasket: 06F 103 483 E = £16.78 inc VAT

    PCV valve cover to turbo hose: 06F 103 215 B

    PCV tube to turbo metal gasket: 06F 145 757 F

    I actually only bought and replaced the PCV valve cover assembly and the PCV valve cover gasket (always best practice to replace gaskets and seals when replacing the associated parts), which came to less than £57 inc VAT. But if I remember correctly, all four parts would've come in at around £80. Considering other older revisions of the PCV alone on eBay were shifting for £45 inc postage, I'd say going to Southampton TPS was a much better choice. I hear they're pretty good when it comes to returning parts you might've bought that were not correct for your car.

    Result!

    Hope this info helps someone.

    This might be worth considering. I had this done recently at my last service, only around £65 to have it done. Definetely noticed a difference aftter in relation to general running and idling of the car. A lot smoother afterwards.

    Relatively an easy fix too.

    Would be good to see the insides of the inlet valves after the chemical clean to compare against the walnut blasting cleaning.
