ABS fault?

[David P]

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?

[David P]

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?

Abs sensor? /Wheel bearing , Complete hub assembly i believe.

Just a possible, Have you plugged them back in or disturbed the wiring?

[David P]

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?

[Dangerous Dave]

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

[David P]

That does sound the most likely. Thank you.

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

[David P]

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.
