[kevzy]

hi iv got a 140pd leon just had it MOT'D last week passed with flying colours... noticed when i had the windows down everytime i go through a little bump on the road i hear a metal sound like something is loose.. now i got worried so i got the car up on a ramp cant seem to see anything loose under the car its deffo coming from the rear iv checked the suspensions springs all looking fine... has anyone else had this problem? what can it be?


thank you for your help

Noises and rattles are not uncommon on the Leon. It does sound like the noise is coming from underneath rather than inside. Noises have a habit of being misleading as to their origin so don't discount that it may be coming from the front.

The easiest way is to find a garage with a Shaker Ramp. If you wish to do it yourself, some of the causes can be :

Exhaust
Heat Shields
Fuel / Brake pipes behind the undertray
Stones on the undertray
Brake Disc Stone Guards
Loose brake pad
Shock Absorbers

Good luck.

Check in the rear bottom arms where the springs sit for stones. I have a gravel drive & occasionally stones drop off the tyre into that. The first time it happened I thought something was seriously wrong. Reach under the car & hit the bottom arms with something like a rubber mallet. If its stones you will hear them. A right pain to get out though.

If you have exhaust tail pipe trims check they are tight.

Ihad this issue with my Leon when I fitted the coilovers my mate broke one of the coilovers shock absorbers so had to use the standard one and 2 days later I could hear a metal on metal noicelike a piece if metal was being rattled in a can. It was because my standard shock had been killed by the lower springs. Could be that mate.

right guys found the problem got under the car properly and in the arm a piece of my rear spring was dropped in it that was making the sound! now then need advise on it do i just change the rear drivers side or change the passenger sides with it ? and how much do the springs cost? thanks

The OEM springs are £70-80 each depending on the suspension specs (paint marks on the springs). Probably best to change both.
