    ASR button

    I have a 2003 Passat 1.8T equipped with ASR, but never used it before.

    I wonder when should I use it?

    If I push it in, the indicator will lit up in the console with yellow triangle, is that mean it is enabled or dis-abled?

    Disabled. Simple, nobody wants to drive with a light on all day long. Or do you?

    You'd better duck...

    ...'cause you're gonna get flamed.

    Anyway..."ASR" stands for Anti Slip Regulation, more commonly known as low-speed traction control. It's a system that invokes your anti-lock brakes when one freont wheel has traction and the other does not. (Generally, this occurs when turning from a stop on slippery pavement or when starting from a stop on ice.) The purpose is to slow down the spinning tire so that both tires provide grip and get you going. It's effective up to about 25 mph.

    ASR is in effect UNLESS you push the button in, which disables it. I can't remember disabling it even once in 105,000 miles on my 2001.5.

    Check your owner's manual for a decent description of the ASR function.

    or disable it if, like mine, it comes on all the time when it shouldn't.

    No rhyme or reason though it does consistently come on when I go up one on ramp to the freeway. Car slows to 25mph or so.

    Big fun if you forget to turn it off before you get to the ramp and you have a line of cars behind you.

    On the 1.8T, I disabled it on any turn that I had to make quick. It would cut boost while trying to pull out. I would rather have a little wheelspin and stay in boost.

    No ASR on the 4MO. I have had 1 tire slip on the right front under full power. You can feel the power transfer.

    According to my 02 owner's manual, it activates above 25MPH. Up to 25MPH the EDL takes care of business.

    Have a noise problem on the road over 50 mph. No noticeable noise around town. Both half shafts and front wheel bearings have been changed within 2 years. Noise sounds like a wheel bearing or cv joint and pitch changes with speed. On highway tried turning to the right then left abruptly but the noise stays the same. Decided to put it on jack stands and run it to see if I could better determine where the noise comes from. First it complained the parking brake was on. Then the ASR light on the dash would flash. Disabled ASR with button. With the car in 1st gear (Manual transmission) The fronts wheels would turn, then stop monetarily, then start rolling again. I would say run for 5 seconds, stop for 1 second and repeat. Is this normal? Can I run it up to 60 mph on jackstands and rear wheels chocked? 2003 passat 1.8T awm manual transmission.

    Wait I thought it was the other way around that When the button is pressed it IS on. Because when my wheels spin the light turns on and then once the wheels are corrected the light turns off again.

    For 15 years that I own this car I thought the same and always in the snow and ice I pushed the ASR.

    I could have swore I read that you can turn it on manually or have it set to auto though.... Now i need to look at my manual again.

    If the ASR light is on in the instrument cluster, ASR is disabled. No light is normal on condition.

    Wait I'm confused. So when my wheels spin out of control and the light turns on I feel the car correct itself. When my wheels are normal again, the light turns off and everything is fine. Is my car not normal or something? It's a 2002 V6 GLX.

    Default, ASR is on. (Light is off)
    When button is pressed ASR is disabled/off. (Light is on) (Resets to on next time the button is pressed or engine started)
    While driving with ASR on (Default condition), if a wheel starts to spin the ASR is activated and the light flashes.

    A simple description. The ASR uses the ABS to prevent one wheel spinning, but if both wheels spin it reduces engine power.
    In conditions where you need some wheel spin, such as snow or loose sand, the engine power can be reduced to a level too low to drive;
    this is where you need to disable the ASR.
