Hi All I am looking for some pointers in trying to track down a very loud resonance at 2500 rpm. It seems to come from under the dash behind the speedo, but obviously noise travels. It's present stationary and moving, in any gear. It's very pronounced, and can be clearly heard over 37db ear plugs. It's really is spoiling the pleasure of driving the car, it's like having a rev limiter, because I don't want to go over the resonance point, and hate it as decelerating back through it. So far I have checked: All the instruments, and the brackets holding them The wiper tube, fixings and plates. Bonnet and nose, happens with them off the car. Gearbox touching the Chassis, there is a gap (not much, but a gap) Column clears the exhaust, and the exhaust is not touching anything. Touching the dash, outer column, steering lock, knee pads, coil cover, windscreen, heater, battery, airbox, ECU, side skins, fuse cover, all to no effect. Basically, if I could touch it when the engine is running I have, yet the resonance exists. So, where next to look? Chris.
