    My usually rock solid S40 developed a total loss of power a couple of days
    ago - it would start and idle and pull away - but then refuse to
    accelerate - gentle coaxing got it up to 20mph - but any attempt at
    accelerating beyond this was futile and even the slightest hill was a
    challenge - luckily a service centre is mostly down hill from me...

    They have had the car two days and say I am into several hundreds of pounds
    to fix - some valve (GRD valve(?)) was faulty and had welded itself to the
    manifold - so they were looking at a long and expensive fix.

    Well I have 'googled' trying to find any reference to the part as they
    named it - and cannot find any. I would not usually be suspicious other than
    the car had a full service on Monday this week, at the same shop. OK
    coincidences can happen - but I don't want to be spending this much money
    unless I really have to. And the car is seven years old, so things break,
    but things that break usually have a name that you can identify don't they?

    Try searching for an EGR valve and You'll get on much better! It's an
    Exhaust Gas Recirculation valve. They're known for seizing, either
    open or closed, and they will give the symptoms you describe. It could
    also be the turbo wastegate stuck open, resulting in no boost
    pressure. Not sure what the S40 system is like.
    Also, yes, they do regularly weld themselves to the manifold, and are
    usually a real pig to get off. Need lots of heat. Easiest to get off
    after a long blast down a motorway, but I guess that's out of the
    question unless you can get the valve to move manually (hammer and
    hardwood drift!) Engine will normally run fine with EGR completely
    blanked off. Just more smoky.

    new valve is expensive too. I would estimate £300.

    Good luck. At least when it's done it'll be good for another 7 years.

    p.s my E-mail address is completely bogus. Reply to group.
