    Im looking to buy some 20mm H&R's for my S3 but after enquiring about fitting to a local VAG specialist I'm a little concerned.
    The guy said that because my car has ACC there is a chance that after it has been lowered the system could stop working and the only way to fix would be a £500+ re-calibration at Audi.
    This is the first time i have heard of this and was just wondering if anyone else had a similar experience?

    That's a new one, £500 calibration sounds a little expensive, but it depends on if the calibration requires a new module to be set from scratch, best to get a definitive from audi dealer face to face, decide whether to inform about the springs or not.

    Not an Audi but on a vehicle equipped with ACC I'm lead to believe that the cone that the ACC module emits needs to be set accurately within 1.5 degrees by the adjuster screws as it leaves the factory. Could see how springs would effect this but if it was that sensitive surely would tyre pressures and luggage, etc would effect it?

    It was Adaptive Cruise Control.

    Wheel alignment settings differ for cars with and without ACC, so yes, lowering springs will affect the ACC calibration (and the geometry) so both have to be set up.

    It shouldn't be £500 though.
