C5 2.0HDI 100kw 2007, wiring diagram engine compartment

[toolfan]

Hello

Has somebody a wiring diagram showing the ECU and its connections to the egine controlling functions? I try to find a fault in the wiring of the turbo charger magnetic solenoids. Probably a short / broken wire.

Thanks!

Provide your VIN and I'll be able to put something up. Please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff.

Thank you, much appreciated!

Marc, I am getting into it, checking the diagram. I downloaded the list of numbers/ components from the diagnostic forum here. But many numbers are missing ( for instance 1285, all the 11xx, and more). Do you have access to a matching list? Would be great.
Thanks for your time!

Sorry, no. The list is only to assist, and does not include wiring codes, only most component codes. I can help with some of the missing ones if you specify the ones you need:

1285: inlet air heating solenoid valve /

If you need some wiring codes, specify them here and I will see what I can provide, as long as there aren't too many.

Great thanks!

The ones which I really don't know:

1158
1160
1208
1220
1291
1297
1380

PSF1 (just to confirm my guess - the engine room fuse / relais box)

Btw: I have Sedre and Dockbackup installed on my laptop, but I can't get the wiring diagrams showing, I am getting errors. Tried many hours, gave up. Must say I am not a very experienced computer guy....

Edit: I've now added the 3 that were missing, thanks.

Correct PSF1 is the Engine Fuse Box.

Many thanks Marc!

Took the time to check and measure to find the fault. Not yet succesful. One question came up: When starting the engine, I noted a short current spike to the turbo pressure solenoid (regulates the vacuum to control the turbo vanes). But then the valve shut down and no turbo pressure while driving. Does the ECU-software do a test/initialisation of that solenoid when the engine is started? Like to make sure the position of the turbo adjuster-position is fine?

I try to better understand how that turbo system is regulated. (P2562, none matching position of the turbo position sensor)

Thanks for any comment!

The turbo pressure is checked using a special measuring tool, where, when fitted, the engine should be accelerated to 4000 r.p.m. The pressure should be 1 ± 0,2 bar(s).

Thanks for the information. I have no turbo pressure at all, the solenoid which regulates the vacuum to the turboadjuster is not getting correct signals. I try to find out why... Checked the wiring and connectors, all fine. Something inhibts the ECU to activate that solenoid. I will find it one day...
