Mk1 2.2 Hdi Exclusive Estate 2002 C5 With Esp/asr Fault And Anti Pollu

[Webb]

Hi all

I recently purchased a 2002 c5 2.2hdi but seems to have a few issues.The esp/asr fault keeps appearing when accelerating to about 60/70mph also the anti pollution fault appears at the same time and the car goes into limp mode. I was told it was a issue on the air intake side so I replaced the air mass flow sensor and air filter also cleaned the egr valve with spray, unfortunately none of these has helped does anyone have any advise as it would very much appreciated.

Welcome to th eforum.

 

If you have not had the fault codes read this would be a start to find out what is wrong rather than replacing lots of parts hoping to get the right one without wasting too much money. The faults described are probably all the same one with limp mode given to minimise pollution.  You can also check if the swirl valve actuator at the gearbox end of the cylinder head has broken - it is a common fault where the plastic cup on the arm breaks. A new actuator (called a diaphragm by Citroen) is about £25, if it is just the cup that has broken it is possible to swap them over, other wise look on the C5 Technical section pinned Common Problems topic for advice on how to replace it.
