My Bonatti Grey TDV6 HSE went haywire last week after three days and less than 300 miles. Six warning lights came and remained on relating to suspension, ABS and parking brake as well as display warning of HDC and special systems failure. The speedo also stopped working. That all these warnings occured at the same time suggested to me an electrical fault and, indeed, the vehicle seemed to be working normally. Having taken the car in yesterday my dealer has reported back that their diagnostics indicate a rear wheel speed sensor has failed. Whether this could have been responsible for all the above remains to be explained.
