I have a 08 c5 1.6 diesel, ocassionally the car stalls with no warning. The power steering brakes fail. it is very dangerous. a sign "depollution system faulty comes up. The car will come to a stop. I turn off ignition, restart car . it starts immediatedly no problem and no warning sign on dash. Any ideas please. I am afraid of it happening on motorway especially on fast lane.

I bought a 08 c5 two years ago. Discovered same problem. It was leaking before I bought the car. After two years and several garages including citroen dealer all diagnosing the o rings as the problem i discovered myself it was the seal on input shaft exactly as above picture including rust. I was lucky to get a second hand steering rack out of a 2012 car. there was a small bit of rust on input shaft of new rack. I put grease on shaft and hope this will prevent problem in future. There is obviously a fault in the design that causes the problem.
