Control solenoids Valves

[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

Kenny: Are you trying to overtake Marc with total component replacement on an X7? Marc only has the cup holders to do for a full house!

Marc only has the cup holders to do for a full house!

He has two?

[GiveMeABreak]

3 actually!

Don't forget the 2 in the back seat armrest.....

@Kenny - I'll sort something for you tomorrow.

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

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?

I'm putting a guide together now Kenny, so won't be long.

Removing the Control Solenoid Valves (Turbocharger, Inlet Air Mixing, Inlet Air Cooling & EGR) on a DW10CTED4 C5 X7

Location Of Valves

(1) The turbocharger pressure regulation electrovalve. (2) EGR cooling solenoid valve. (3) Inlet air cooling solenoid valve. (4) Inlet air mixer control electrovalve.

Disconnect the battery following BSI Reset / Battery Disconnect / Reconnect Procedure

Remove: The protector (5) The bolts (6) Unclip: The tubes ( as "a").

Remove Heat Shield

Remove as shown

Turbocharger pressure regulation solenoid valve

Remove the bolts (7). Uncouple and move aside the vacuum circuit pipes ( as "b"). Note: Mark the position of each vacuum pipe! Disconnect the connector (at "c"). Remove the turbocharger pressure regulation solenoid valve (1). Refitting Refit the turbocharger pressure regulation solenoid valve (1). Couple the vacuum circuit pipes ( as "b"). Note: When refitting, do not reverse the vacuum pipes . Connect the connector ( as "c"). Refit the bolts (7).

EGR cooling solenoid valve

Remove the bolts (8). Uncouple and move aside the vacuum circuit pipes ( as "e"). Note: Mark the position of each vacuum pipe! Disconnect the connector (at "d"). Remove the EGR cooling solenoid valve (2). Refitting Refit the EGR cooling solenoid valve (2). Couple the vacuum circuit pipes ( as "e"). Note: When refitting, do not reverse the vacuum pipes . Connect the connector ( as "d"). Refit the bolts (8).

Inlet air cooling solenoid valve

Remove the bolts (9). Uncouple and move aside the vacuum circuit pipes ( as "g"). Note: Mark the position of each vacuum pipe! Disconnect the connector (at "f"). Remove the inlet air cooling solenoid valve (3). Refitting Refit the inlet air cooling solenoid valve (3). Couple the vacuum circuit pipes ( as "g"). Note: When refitting, do not reverse the vacuum pipes . Connect the connector ( as "f"). Refit the bolts (9).

Inlet air mixer control electrovalve

Remove the bolts (10). Uncouple and move aside the vacuum circuit pipes ( as "j"). Note: Mark the position of each vacuum pipe! Disconnect the connector (at "h"). Remove the inlet air mixer control electrovalve (4). Refitting Refit the inlet air mixer control electrovalve (4). Couple the vacuum circuit pipes ( as "j"). Note: When refitting, do not reverse the vacuum pipes . Connect the connector ( as "h"). Refit the bolts (10).

In all cases, follow the reconnection part of the BSI Reset / Battery Disconnect / Reconnect Procedure

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.
