Faults and Technical chat for the Citroen C4 Cactus
That exhaust bracket is unsurprising. Lots of Citroen do it. I had exactly the same problem on our C3 Picasso at 3 years. The exhausts last well but the brackets are cheap mild steel . The weld on our car took 5 minutes at my local repairer and MOT tester (not a dealer) was free and five years later has well outlasted the original bracket. Scandalous charge at Robins and Day but take heart some dealers do not offer to weld!
Had to have my exhaust bracket replaced at the last service in March, which was it's third service and first MOT. I wasn't impressed.
