It may not have a post EGR sensor hence the default open circuit value. I can tell you more with the VIN.

It does not have a sensor, I should have realised that but I didn’t notice what car it was, it is the standard EGR failure, not worth over thinking it but for God’s sake only fit a genuine DQ revision unit… six hours grind on your back to find the unit you have fitted is faulty can be a little demoralising.

Thanks Crasher,I've read on your other posts about fitting after market one's and yes it looks like a bitch of a job.

I hate doing them with the car six feet in the air on a lift, on your back on stands outside in these temperatures with antifreeze dripping in your face... well as a younger man I did endure such misery but now it would finish me off!
