Control solenoids Valves

Post by KennyW »

Hi All,

Looking for the procedure to remove and refit control solenoid valves at back of the engine, I'm sure I've seen it on another thread.

I found a version but it has 4 valves whereas mine has 3

Can anyone help

The two in the front of mine are hopeless, Hardly anything fits and is very easy to knock over. I use the ashtray, it is never used for anything else (the ashtray between the front seats)
SO I have 5! Nahnahnahnah :P

I've never sat in the back of my X7 so I had to go out and have look. I didn't see any cup holders so thought the Estate might be different to the saloon but then I saw a little pull out tray in the armrest. Who knew?

Thanks Marc,

Okay I have only 3 valves not 4 as above so they have not bothered to update their files.

The vacuum pipe 7 in service citroen changed at 12291 with one less port.

The removal fitting procedure is the same but with 1 less control valve. I do not know why.

FYI Marc that is the same procedure I have.

I recall I posted posted about it somewhere a while ago now, but can't remember - it was a few years ago now.
