Omega General Help / Buzzing noise
« on: 17 March 2016, 18:37:20 »
When I turn the key in the ignition and all the lights on the dash come on, without the engine being on, I can hear a buzzing noise from the engine compartment. It sounds like it's coming from just below the expansion tank, where coolant pipes join into something larger, is it a secondary pump or a filter of some sort? It maybe unconnected but the drivers side windscreen washer has stopped working, the passenger one is fine. Any ideas what's buzzing?
