Looking for

Post by KennyW »

Hi All,

I'm looking for a diagram show where all the vacum pipes etc go from and to the Turbo and solenoid valves.

Citroen service parts show it partially but not fully.

Can anyone help ?

My car's details are in the signature.

VIN VF7**************[VIN obfuscated, can be read by forum staff].

Kenny

Thanks Marc,

It will give me something to do whilst I have to self isolate, SWMBO has developed a cough, at least I've got 14 days to look it over.
Maybe I shall even get a chance to check the wiring for the suspension ecu as well.

Marc,

There appears to be only 1 position sensor on my air flow meter, is this correct.

The flowmeter for the air mass measures the flow and the temperature of the air entering the turbocharger and transmits the information to the engine ECU. It has a single electrical connection - there are no solenoids / electrovalves on this unless you mean something else.

Not to be confused with the Air Doser (7)
