My 850 T-5 has began dropping RPM's on occasions at first I was led to believe it could have been the gearbox lockup happening doubt it now as it happened today at 40mph, car doesnt seem to be suffering as the drop of RPM is very brief but visible on the RPM Dial.
Anyone got any suggestions ? I wonder if it's something to do with my ABS light being on

It's the ABS ECU at fault had the codes read/reset within 20 mins the ECU Fault code returned and as the ECU has already been attacked I think it's time for a new one
