    I'm at the troubleshooting step of disconnecting the actuator rod from lever to check for free movement of the vanes. I've gotten my thumb on the lever and can barely move the thing, but I'm also fighting the actuator spring.

    What's the easiest way to free up the lever for testing? Just the circlip, just the 2x10mm actuator bolts, circlip + bolts? Looks like tough visibility, even with the hoses out of the way in the picture.

    I look in from the right side of the car and get a bar or something down onto the lever and push. Bit awkward but it works eventually lol

    Or get up to it from below and pull down

    Other option is yeh, 2x10mm nuts and circlip

    Was the car warm when you tried? Getting the turbo hot is supposed to help make it easier and then obviously wear a good set of gloves.

    With everything assembled, put a 9/16" box wrench on the vnt lever on the turbo. Should be able to move it with one finger, even against the spring and actuator.

    Thanks guys, all good tips and info. Not sure I got the wrench on there as luxuryrules intended, but there is nothing one finger about the movement I'm getting either with my thumb or a wrench on the lever. And it does seem to vary with degree of warmup as live4snow mentioned. I'll get a fresh circlip and see how the lever moves when free of the actuator. I would love for it to be the actuator, but we'll see. I've got this sinking feeling there is some disassembly coming up. The job may be rated 2/5 but I'm guessing it's a full weekend for me if I'm lucky.

    I always get them moving on the car, does fine for a good while which is handy if you're in the winter season. That's when I tend to find issues popping up lol

    Its just getting something decent on it to get it moving to start with.

    If the actuator isn't sticking I'd maybe try lubing the vnt lever and seeing if I could get it moving.

    Unless the weathers decent of course
