Re: Spark plugs on old Vauxhalls

mechanical movement making electromagnetic radiation directly or electric currents in wires.

Not convinced it's a problem in the radio itself (suggested by someone else), as it only happens when the rear wheels go over the bump, not the front ones. Something being induced into the aerial lead sounds possible, and the noise really does sound to me like a "data burst", but the Kangoo (2006 vintage) is a fairly simple car. Yes it has anti-lock brakes, but that's about it, all lighting is bog standard wiring loom, and it doesn't happen when I indicate or brake or turn the lights on. What on earth could be sending the data burst?
