Re: Egr diagbox?
The first one looks OK as requested position and reported position match, but in the second one the reported position is listed as invalid. You can't really tell from a static shot - you need to watch the two figures as you rev the engine up and down - they should follow each other closely, and the reported position should stay steady if you hold the revs steady.

Re: Egr diagbox?
Where is the EGR data within Diagbox? I am having trouble finding it. Which menu/option do I need to get live values?
Thanks in advance

Re: Egr diagbox?
You need to look in the engine ECU live parameters IIRC.

Re: Egr diagbox?
Thanks for the quick reply. (I am a bit thick though… sorry!)
Which menu is that under?
Repair >> ?
Fault finding >> ?
Maintenance >> ?
The screens shots above come from the repair section, but I can’t seem to find anything that takes me to live parameters.
Thanks for your help.
