    ABS fault?

    My C30 D5 has recently had new callipers, discs, pads and flexi hoses fitted yet despite no errors lit up on the dash, my BSR diagnostic informs me there is a problem?

    BCM - BRAKE CONTROL MODULE
    0x0041
    Wheel sensor right rear Incorrect signal
    0x0031
    Wheel sensor left rear Incorrect signal

    Does anyone know what this could be?

    Excuse me for bumping this, but I was really hoping that someone would be able to furnish me with more specific information for this fault code?

    I haven't done anything, other than to pay a Monkey Nic to fit a pair of new callipers and pads.

    I don't understand what he could have done wrong with such a simple job?

    Sounds like they might have disturbed the abs connectors when changing the calipers.

    That does sound the most likely. Thank you.

    Maybe "Incorrect signal" is Swedish for "No signal" ?

    It turns out that the Monkey Nic had left the ignition on, or had turned the ignition on during the calliper change.

    To discover this and to delete the consequent fault code entailed a diagnostic check @ 49.95 plus 20% VAT.
