From time to time the instrument panel indicates esp and abs the telephone wireless turns off and back on, the climate control switches off and on the instrument panel states auto lights non operational. The head lights turn off and back on again. All this happens within a split second. The car does not appear to lose engine power. Maybe because it is momentary loss of electrical power. The problem is escalating, becoming more often during journeys. This can also happen when the engine is running and the car is stationary. The can wiring connectors have been checked at OS footwell and have tested ok. There are no signs of oil ingress in gearbox wiring loom and the front/rear sams are clear of moisture . The car has undergone specialist diagnostics and guess what, I have been advised rechecking when the fault is present. Ha problem, it only last for a split second. I would appreciate any ideas. Thnx in anticipation
