Had a dreadful flapping fluttering noise from under our Autotrail Cheyenne tag axle van. First started at 70mph then over time the noise was starting at lower and lower speeds. I thought it might be a bag or piece of plastic caught underneath. Looked under several times and finally the large heat shield over the transverse exhaust silencer caught my eye. When I got my head right in there I could see it was cracked right across. It is a Fiat part so managed to get a replacement for £28. What a bit of junk this heat shield is. It's the shape, strength, and consistency of a disposable baco foil baking tray. It would be ideal for a turkey at Xmas. God knows why Fiat use such a flimsy piece of crap. It has only lasted 14000 miles and five years. Fitted the new one today in half an hour, cursing the git who specified this shoddy part the whole time! Glad that's off my chest.
