Hello,

I have a standard 3 door Ford Fiesta 2004 Model. Petrol 1.4 car. Zetec type. Miliage is: 111858.

2 days ago I started hearing quick fire banging noises that indicated to me the the exhaust had gone. Ford Assist came out (the AA), who said the engine was okay and that it appeared to be the exhaust. I took the car to my regular Ford Service agents not far from where I live in Nottingham.

Fords diagnosed a corroded rear back box and replaced same.

They replaced: Rear Back Box. Supplying also: Muffler Assy - Rear. with Insulator, clamp - hose .

Driving the car away late this afternoon I noticed a grumbling or growling noise from the rear of the car. Which I did not get with the original back box that had been on the car - like the rest of the exhaust system, since purchase in 2005. The cars engine sounds quite normal.

QUESTION PLEASE:

Is this sound normal for a replacement back box, given that it is apparantly the largest part of a three part exhaust system on the car. No such noises were heard before with the original exhaust system.

History of car:

Please note that absolutely no modications have ever been made, as far as I am aware, to the car exhaust, the cars engine or anything else.

This is a bog standard original version of the car as registed in 2004. I have owned it since 2005 and the previous owners were a partially disabled couple (middle aged) living in Harrogate and who, by all accounts kept the car in their garage most of the time. (They went off and bought a car under the Motobility scheme I gather).

Conclusion:

I dare say I can get used to the noise of the new back box. (My car being due its full service in Mid February 2016).

Note also that a Health Check was done on the whole of the car today and the results were all, Green Lit, over the basic essential areas that they checked whilst the car was in. No Amber or Red areas highlighted.

I await your advice please.

Thank you.

Brian.
