Hi,
Ref: VF7**************[VIN obfuscated, can be read by forum staff]
Does anyone know if the C5 RHR engine has a swirl chamber. Haynes does not mention one and I can't find any mention on Citroen box. I have a fault code P2562 (turbo circuit A)
It has started with the hesitation on acceleration again, 5 months after fitting a new EGR valve which seemed to cure the problem. In desperation I removed the connector to the EGR valve turned it round through 360 degrees and refitted it. Hesitation gone, car runs fine but loses some boost at top end ( above 3000 revs) Removed connector cleaned it and pressed the contacts together to make a tighter contact, Much improved performance but still not right. So I could have faulty wiring to the EGR valve but without any wiring diagrams I am unable to check further. I do NOT get the engine management light coming on.
I am now checking all pipes for leaks and keep seeing "check swirl chamber diaphragm for vacuum leak" when reading through forums.
I will also check the wiring to the turbo tomorrow as I believe "circuit A" refers to an earth circuit from the turbo to the ECU.
I really must buy a vacuum gauge.
Thanks
John.

If its the swirl flaps as in the 2.2 you are referring to, it makes very little difference whether they are working or not, or at least it didn't on mine. I take it this is the 16 valve 2.0. you are referring to, I'm not very good with numbers, the 8 valve certainly doesn't have them.

Hi,
I have had confirmation from the Citroen dealer I use that its only the 2.2 that uses the swirl chamber. Thanks. John.
