'HDi's for Dummies' diagrams?

sorry marc, i thought i had at some point previously

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

Hi Dave - I hate to say it, but copying the message from the PM system has just copied the resultant text and not the actual VIN as it has already been obfuscated by the system.

Just pop the VIN in a post under here and I will be able to see it.

Success

Now I'll see what I can find...

[old'uns]

i'm hanging around...but i will admit to looking at other cars just in case i need one fast!!!

inlet doser is a Y shape with 2 butterflies, i wouldn't be surprised if the whole engine is like this....

regarding the RPO i've tried all combinations and still get the error message about activation

Yeah, I saw your engine bay pics, your intake layout is vastly different, not just the butterflies...

You shouldn't be asked for any activation details. Is it possible you've clicked YES when you should have clicked NO after startup?
Close Diagbox(?) and restart, if it asks to Activate, click NO. If it asks to Update, click NO. If you still get asked for verification after that, you may have to re-install, after a clean uninstall.

It's the same set up as on my 407, so at least if it develops the 'hiccups' we know how to fix that!

Ok, so here are the main components of the Siemens Injection Engine Management System with designations in the following table I've constructed:

now i know what i'm doing tonight!

in other news i now have dialog with the car and am currently having a root around...first impressions are no vacuum...quellle surprise
and i have seen somewhere something about particle level full... well may be not that shocked
quick actuator test as well...EGR was heard to make some noise

see you all later

[moizeau]

Splendid, so no movement of either butterfly or turbo on the actuator tests?

[old'uns]

it was raining on and off so that will be tomorrow

i'll post some screenshots later, doesn't look too bad, well not to a untrained 'monkey' like me!, i'm sure someone will see otherwise

OT...36 is the other side of the river to our place?

[moizeau]

Much further south east, almost 23, I guessed you were Le Mans region going by 'Sarthe' as in 'Aire de', I'll be passing there Wednesday, early afternoon, on the way to Caen. And then re passing Saturday! Good luck tomorrow.

[moizeau]

Oh and thanks Marc, those diagrams will be very useful to me as well.

[GiveMeABreak]

No problem chaps - hope they help

[old'uns]

a bit of technical reading for someone.....


no vacuum?


flowmeter air temperature -49 ?


DPF not blocked? airflow air temp now +21 ? good or bad?


additive injector tested and sounds heard so OK?


airflow air temp now back to -40





just as an after thought, is it a possibility that the vacuum pump has failed hence why someone previous 'bodged' the lines?

[GiveMeABreak]

I shall have a squizz at those codes tomorrow Dave
