    Right - forgot about the turbo control valve. So the only way to do it then is to modify the ECU parameters.

    Bypass not waste gate

    Volvo turbos have exhaust bypass, not waste gate.

    i.e. exhaust gasses can bypass the turbo impeller, lowering boost.

    instead of excess boost pressure being "wasted" through a pressure relief...
  3. Anybody replace their coolant level sensor?

    OMG, this has got to be the easiest job on the whole car ! ! LOL, I would put it at just slightly more complex than checking tire pressure . . . or topping up washer fluid.

    Why on earth did I...

    Key won't turn in driver's door

    99 v70XC - would anyone happen to know what might cause the key not to turn in the driver's door? I suspected the lock was frozen but it went from not budging to completely free. Usually a frozen...
  5. Solved !

    Thanks Redoak.

    Didn't exactly show what I needed. I ended up bringing my 13 year old with me because his eyes are better. The latch release rod passes through a tiny oval hole which I couldn't...
  6. more info

    It's difficult to offer advice - what code are stored? How many miles / kms on the vehicle?

    Starting - some would say fuel pressure, possibly crank position sensor. If it resolves after the car...

    I wonder if the boost problem is the problem . . .

    Talking to a good mercedes mechanic, he really downplayed the role of the O2 sensor as one of feedback, not primary. I'd like other opinions on...

    these cars seem to take time to bounce back and if the O2 sensor is fouled due to the other problem it will affect running. May resolve in time. They are supposed to last about 60k miles according...

    dealer should be able to solve this for you.

    I believe the turbos get the colder t-stats and cars driven in colder climates get the warmer ones to help with cabin heating. I've got a turbo in...

    I've got a thread running on intake leaks, which I have been looking for on my car and not found.

    In trying to solve this I talked to my mechanic many times, as well as paying him several times. ...

    I suspect they were used at the factory during assembly. They're too weak to take any load. Alignment of the cradle with other front end parts is pretty important. Heard of some guys cutting them...

    So long as you know it's shot . . .
    I removed mine from below. Lot's of release-all a few hours in advance. Cut the wires and use a deep socket. You might have to break the back of the sensor off...

    I was pretty convinced this was an intake leak but used propane last night and couldn't find it. Wrong technique ? or should I be thinking about fuel pressure fluctuation?

    Fuel trims were...

    Awesome thanks. Yes, I think it's time to put some effort into this.

    I also recently had a loose axle bolt and no noise. I think it's just a question of how much movement there is in the splines as to whether it will click or not. Certainly did cause me huge...
  18. Have you ever repaired an intake leak - where was it?

    I have unmetered air entering my intake and cannot find the source.

    Please share your experiences with me - consider it a poll, but I don't know what the voting options would be. . . so you tell...
