Rattle around battery ?

[fletch8]

Around 6 weeks ago now I took the battery and ecu out.

Since doing this my car has developed a tin like rattle as I come off the accelerator and the revs are dropping. This immediately goes if i put the clutch down and is more frequest at higher speeds.

Im aware there is some sort of mount underneath the battery tray. Could it be down to this at all as it sounds like its coming from that side of the engine.

Sorry for the vagueness, doesnt happen when i just rev and let go on the drive though so hard to determine the fault.

cheers guys

Check the ECU mouting point has not snapped. This can cause rattles.

My ecu housing had 1 of the mounts snap and all it did was squeak and rattle for ages, i finally found it when disconnecting the battery as it was the mount right above,
