VDC/ Slip/ ABS Lights are on

[josephcaro]

I have a 2004 Q45, the VDC/ Slip/ ABS lights are on. Occasionally they will go off for two driving cycles and come back on again. I hear a clicking sound coming from the firewall area when the car idles (it's intermittent). I tested the VDC relay box as outlined in the service manual, it's OK. I'm not sure where to look from here, any troubleshooting suggestions would be greatly appreciated.

Welcome to NICO.

In most cases bad ABS sensor triggers VDC/Slip/ABS lights to come on. It is a common issue with some F50. Take a trip to the stealership for full diagnostictest.

Good luck.
