Sorry, I misread "air mixer" to be air heater, which I now believe is the EGR throttle as lI forgot tha later vehicles like yours only have the single air doser.
Same test principles apply.

If you post your VIN number, an accurate diagram can be provided by GiveUsABreak.

EGR valve and Air Mixer (also called EGR throttle or Air Doser) are two separate components. You'll have to wait for admin to provide further VIN-specific information.

This is an example of how they may be represented in the Diagbox tool...

No, leave the particle filter alone - that is not indicated as being at fault.

Get your mechanic to check the vacuum circuit as described on the previous page where I listed the fault codes. It has the suspect areas listed.

Item 8 (air doser) and item 6 (electrovalve) are main suspects as they are prone to contamination (sticking).
I would test these first (further tests may be necessary).

Item 8 houses two butterfly valves. Clean and check they both open and close smoothly.
If not, replace air doser.

Example


Item 6 is has a very small internal air filter. If internal air filter can be cleaned, clean it.
If not, you may need to replace electrovalve.

Citroen C5 is a great tool.
repairers are very weak, this is not enough to solve the problem.
I'm researching it.everyone is helping.then I share with repairmen.
result 0.

Please note that on the DW10C engine, the by-pass function is not active, the hot air (by-pass) flap is only activated in the event that the cold air (mixer) flap seizes.

So although you have the double air doser, the left hand plug is purposefully disconnected (the wiring plug will be hidden) and there should be no vacuum pipe attached either. So DO NOT connect this up, as it is designed to be left off!
