  • Weird thing with my car

    I’ve just got the car going again after breaking the throttle cable last week.
    Now when I put my foot down it sounds a bit wheezy then a bit more foot and boost comes in but surges between 1 bar and 1.5 bar, very odd
    No codes on Vagcom and holds 1.5 bar on a boost leak test.
    PCV is deleted and CC vents to atmosphere.
    Mighty vac on ECU and no leak internally. It definitely wasn’t doing it before the throttle cable incident!
    Might try changing the MAF

    Boost is the new rock and roll!

    It was the 1Bar WG spring.
    ECU trying to control the boost.

    I swapped in a stock spring and it’s fine.

    I guess maybe before the throttle cable broke I wasn’t getting full throttle so didn’t notice it.

      That'll do it! No need for a stiffer spring really.
