I've recently bought a 52 330 CI Sport Auto with 97k and gets an occasional buzzing / ringing sound from the passenger side of the engine. Only puts in an appearance when it's warm and only if the engine has been switched off and the on again ( short stop for shopping, petrol etc). Only happens on acceleration and seem load related e.g. noisier if accelerating up a slope. BUT, it's intermittent! Any ideas? Many Thanks
