Duncan684 Posted March 25, 2015 Share Posted March 25, 2015 Can anyone help? I have posted this before, I own a 2003 mk3 mondeo, at certain rev ranges there is an annoying deep rattle? sounds vaguely like either heat shield, air filter box or exhaust brackets? can any one give some guidance, I have tried to re create at standstill whilst trying to listen under the bonnet, however to no avail? can anyone help?

Ben87 Posted March 25, 2015 Share Posted March 25, 2015 Is it a petrol or diesel? Sent from my iPhone using Ford OC Quote Link to comment Share on other sites More sharing options...
iantt Posted March 25, 2015 Share Posted March 25, 2015 If diesel, 5speed gearbox or 6 speed box? Quote Link to comment Share on other sites More sharing options...
pragmatix Posted March 26, 2015 Share Posted March 26, 2015 Check the turbo pipe for hitting the front cross member Quote Link to comment Share on other sites More sharing options...
Ben87 Posted March 26, 2015 Share Posted March 26, 2015 I agree with pragmatix, check the turbo pipes that bolt onto the front of the subframe, have seen them snap and rattle under boost. Sent from my iPhone using Ford OC Quote Link to comment Share on other sites More sharing options...
