we have a 2000 S40 w/about 65k mi and just after we bought it the turbo line started to leak ( which i understand is a common prob) and shortly after the o-ring was changed it started to run like crap... better when it was cold out, worse when warm .. read codes @autozone came up w/#3 misfire so i changed plugs (#3 looked like crap) fuel filter and air filter w/marginal results. took it to local dealer and they read codes and it came up w/(and i quote from bill) ECM 44- needs spark plugs & oil change--aftermarket plugs in car needs 60k service and valve est 608.00. when i inquired about this valve they gave me the name (which has since slipped my mind) and we looked in the VADIS detail to find it > It is in the cylinder head page and is called the exhaust solenoid by the parts listing . from all i can see it appears ,by the VADIS exploded veiw to be on the front of the head but there is no other info about it and the [email protected] the dealer stonewalled me on its location etc.... i smell one of those "the book calls it 608.00 but it really only takes about an hour things". can you shed any light on this? i know that the part,even if i buy it from the dealer is only about 85.00 . I currently own a 750il and do all my own work including engine and electronics myself so tearing this thing down won't be a big challege but it is my wife's car and i would rather NOT start on this till i am sure of exactly where it's located and what else i am going to need... or if i even need to do this at all!! i want my face to remain on the front of my head ...lol thanks a lot talk to you soon brian duffy
S40 Rough Running

Did you find the solution to this problem? My 2002 Automatic T4 is doing the same thing... And it also started after having a Turbo return line oil leak.. I've cleaned the injectors, throttle body, replaced spark plugs, filters, everything, and it still has problems mantaining a steady idle speed.
It first used to give a cylinder #4 missfire, but after changing spark plugs that problem went away, but now i just can't figure out what is causing the uneven idle.. Sometimes it feels as if it is going to stall, but recovers. Idle can vary between 600 and 1000 RPM, and the problem seems to be intermitent... There are some times when the engine feels absolutely quiet, better than new. If I leave the car on neutral, the problem does not occur. It only happens while on Drive.
Any hints?
