    2A87 VANOS

    welp, the dreaded vanos issue has finally hit me Click here to enlarge


    just to make sure my process of resolve is correct:

    inspect camshaft ledge for excessive wear before cleaning/replacing vanos solenoids right? thanks in advance.

    You don't want to go there right away. Its time consuming taking the valve cover off and you'll have to take the cam ledges off to look at them. I'd clean the vanos solenoids first and test them with 12v power to see if they open/close. If that works and you still get the issue then I'd go after the ledges.

    Dzenno's way is probably the right way to do it.

    However, I'm lazy. When it hit my old car around 60k, I just replaced both solenoids and the problem never came back. Most of the times it's solenoids. Plus your car is low mileage if I remember correctly

    49k miles still under factory warranty, but I doubt I can make it happen stock nor do I want to de mod my car which would cost more than the actual solenoid lol.

    its just the exhaust side error code.

    Like light bulbs, they age similarly, but inevitably one fails before the other.

    Agreed especially when it's a cheap fix. change the solenoid. if it doesn;t fix it, take it out, sell it. de mod and go in Click here to enlarge

    I had this problem recently. I cleaned up both solenoids with carb cleaner and air, and they work great now, no more codes.

    Odd, I just thrashed the crap out of my car multiple times and not a peep. Hopefully a cleaning will do the trick. Click here to enlarge

    i also vote for checking and replacing the solenoids first. I've dealt with this before and the intake solenoid was acting up. 15 minute replacement job and the issues never came back.
    From all the things I've lost,
    I miss my mind the most!
