Fiesta Exhaust problem

[smm66]

Hi,

Can anybody tell me what might be the cause of the following problem?

- exhaust gas under the bonnet

- strange repetitive noise, probably from the exhaust system.

Car: Ford Fiesta TDX 1.4 Diesel from 2004 (90000 miles)

Any suggestions?

Thank you,

first check all exhaust joints to see if there is anything blowing also any hoses for the same could be a partually blocked exhaust causing back pressure but unlikley on 2 year old car but stranger things have happened
