Can a blocked DPF cause cam belt failure?
I own a 2010 Ford Fiesta 1.6 diesel with 101,000 miles. Recently the cam belt failed. The car is back with the dealer who tell me that the DPF is blocked, which caused the cam belt failure. Is this likely?
This is why I put a limit of five years or 60,000 miles on a timing belt and waterpump whatever the manufacturer says. With cars under 20,000 miles I've stretched it to 7 years, only to find that the waterpump was about to fail anyway. A completely blocked DPF would prevent the engine exhaling, but it couldn't have blocked so suddenly that it snapped the timing belt.
