The rear exhaust hanger on the Diesel Citroen C3 is designed to self destruct after a number of years. The broken rear hanger may not be noticeable straight away as the other hangers are quite strong. A quick look under the rear of the car is all that's needed to inspect for a broken hanger.

The hanger is not available as a single item from Citroen, but comes with the rear exhaust silencer (back box). There are after market suppliers who have a modified part that is available without the exhaust silencer.

This is a modified hanger, comes with a split pin for the shaft, protective coating, 2 bright zinc plated nuts and a long BZP bolt for easy fitting. The hanger feels very strong, but flexible enough to be an easy fit. This is the item I fitted aftermarket exhaust hanger for Citroen C3 on ebay (here).

The new straps are available here.


The finished job, took minutes to fit, no need raise the car. There was plenty of room to access the rubber hanger and get the strap around the silencer. The long bolt made it easy fit and the second nut acts as locknut. Just bend the split pin arms out to stop it from falling out.

I have the exact same problem.

Do C3 Hdis come with a list of identical failures?

Yes, faulty injectors leading to non starting HDi, clonking when accelerating or starting due to a worn gearbox mount, wipers operating when indicating left due to a faulty COM2000 and broken front springs. I won't even mention the faulty clutches ;)

Hi
When I change the exhaust strap, do I just somehow pull the support arm out of the rubber mounting or do I have to remove the mounting first?
Thanks

Just pull what's left of the rusty bracket from the rubber mount. The new one may come with a split pin to make it easier to fit.
