    My hopes of needing a new ABS sensor have been quashed by VAG COM telling me that I have a sporadic issue with my Longitudinal Acceleration Sensor.

    I believe Audi charge over £100 for a replacement, but am wondering if there's anywhere else I may be able to get one from?

    It's probably not even worth buying a second-hand one as I believe they've got to be programmed in via a full VAG COM unit and for it to become faulty 3-6 months later is wasted money.

    It's for a 2000-plate pre-facelift S3, btw.

    I have bought Wheel speed sensors from Euro Car Parts before that have only lasted 3 months and I've only saved myself maybe £20.

    My advice would be to buy a genuine one. You buy cheap and you buy twice, trust me.

    I called up Euro Car Parts and they said that they wouldn't even do me the sensor that I need and that I'd need to go to a dealer direct.
    Looks like I'm paying out >£100 then + labour.

    Forget labour mate. Change it yourself it's fairly straight forward. I'll try and find a guide.

    Also try getting a quote from Stoke Audi on here as it might be slightly cheaper than your local dealer and he can post it to you.

    Ah right ok - Yeah I thought you had to have them programmed in but if it's a 5 minute job then all's well! I've been researching it all day and have found where they are located (I believe by your left knee on pre-facelift on the passenger footwell up front).

    Remove the Glove box (a few bolts) take off the dash end panel (open passenger door) it pulls off. remove the multiple torx/bolts and the inner panel will come off, can get at the sensor then, i found it easier to remove it with the bracket then change it and put it back. then after that first time i started it the light never came back on. happy days

    Facelift ones are under the steering wheel which makes life a bit easier. Mine had a bent bracket so wasn't sitting completely flat. Worth noting there's a calibration feature in vagcom for them also.

    Very odd - everywhere I've read (and mine) has both sensors under the steering wheel. Is yours an 01?

    I thought this originally then was told that on facelift there's a "dual sensor" (yaw and latitude) and then a longitudinal sensor (G200).
