2007 Discovery 3 TDV6 HSE Auto Buckingham BlueDiscovery 3

Ok.

So I've plugged my iid in just now and these are the live values I have for the map and mad sensor while the car is running. The first photo is before putting my foot down and the secound when I revved it up t 2000 revs per minute.

I'm also adding a couple of other live values I get sto do with the egr valves.

Any ideas as these values don't make any sense to me as I haven't a clue what they mean. Do they look good or bad?

Thanks.

It means your EGRs are Censored . Blank and patch...

If the patch has already been done, and not been overwritten in the meantime, it's most likely a fault code has been missed

This is assuming there is only the EGR codes remaining in the PCM memory...

Update:

After help from Bodsy (thanks Thumbs Up) and following his advise of re installing the egr patch again I can say after over 150 miles of driving no light has come on the dash and the problem seems to be resolved.

If you have the same problem as I did after having your egr valves blanked, butterfly removed and patch applied then do the above.

Hope it helps.
