    Default 306 Idle stepper thingy

    I was a little annoyed with my little Pug this morning. After giving her a good poke down the Boulevard she decided to stall once I had come to a stop. Restarted okay, but then stalled again when coming to a stop. Once I arrived at work I found that she would be okay if I was releasing the throttle from revs say below 2000, but giving it a rev up to say 5000 the idle wouldn't catch and she'd stop. I have had this problem a few times before, all after washing the car. But this time it just happened.

    I'm guessing it is the idle stepper motor solenoid thing playing up. I've got instructions on how to remove it and clean it, but I am wondering if anyone out there has done this and could give a few pointers.

    It's a very common problem. Remove and clean with carb. cleaner. Only run on 98 octane. A new stepper motor is approx. $300.

    Stoney, I'm pretty sure Alan S recommends spraying a touch of silicone spray inside after you've cleaned it.

    I also had stalling problems and followed Alan's advice. After spraying with silicone, I haven't had a problem since.

    to take off youre stepper motor (GTi 6 only) you need too find a black round thing going into a small plastic block at the firewall side of the throttle body(where the rubber hose from the filter bolts too the intake) just next too the start of the intake pipe on ya most right.has a hose going too it too. 2x 10mm bolts hold the block,loosen them and the hose then u nearly there.if u lucky they have normal screw heads but probly wont. ul need a TORX srew driver too loosen the motor. when out give it a clean with a rag,if u got carby cleaner use that aswell and a spray in the plastic block too. dry befor putting it back in. easy! happy drivn if it is that
