As above, really pissing me off now, was gona strip bits down today to try and source the problem but its pissing it down with rain! It usually only happens when i go over bumps.

Doesn't sound like its from the engine, just behind the centre of the dash somewhere maybe at the back of the bulkhead.

Just a long shot to see if anyone else has had this before i rip my motor to pieces!?

lol i went to see this old nova once, and i opened the bonnet and there was 2 rats inside the engine bay!

try removing the scuttle panel and black plastic bit, to see below there, just to make sure there isnt anything loose in there, try shaking the car with bonnet open 2 see what knocks, and try sitting inside with somone else shaking car 2 make sure its not inside?

lol... i got the same prob, defo not from my engine bay or under the scuttle as ive checked it PROPERLY. its defo from behind my dash, my toad alarm is secure behind the dash too.

what could it be? ive felt around everywhere possible and no wobble parts, also ive had the clocks out and checked for any loose things from there, but no joy? its defo in the car behind the dash tho... possibly coming from driver side... thing is on the driver side you can more or less feel everything behind the dash, but i cant put my finger on it??

also mine makes the noise when i hit every tiny bump. cant be serious because the car just passed mot, someone help me put my finger on this annoying noise ive had for over a year

Your sure you've checked everything under the scuttle panel, taken it all off.......wiper motors.....i never imagined mine to be my alarm siren but it was at it only sat about 5mm away from a piece of metal! Are you on an aftermarket alarm, alot of companies store them above the glove box just loose....could be that.

Double check everything under the scuttle. It has to be something substantial in size id say for you to hear it when driving.

oh and yeah took the wiper arms off, took scuttle panel out, took plastic covering off and felt everywhere... all is ok there. and by the way it only happens when i hit every bump possible, doesnt do it when i turn or go/stop..ect. only bumps. its a high pitched noise like i said before like if you tap a key on metal/bodywork of car.

Can you feel in through your steering, could be steering rack related or something behind the inlet manifold area.
