I thought this would be the situation when you reported that connecting the new EGR valves without fitting them didn't cause the EGR air-flow fault that occurs in later MY07 vehicles.

As you have indicated there are 2007 production year vehicles that are 06MY spec and there are 2007 production year vehicles that are 07MY spec- I have confirmed that mine is a proper 07MY through topix and has the parts changes for the 07My like uprated fuel filter etc. The 07MY ran into the 08 production year.

So it seems that my car is 07my in all aspects except for its ECU map.

However there have been plenty of reports that blanking will work on a post 07MY - at least for a while before the EML comes back - so it may just be a issue like that.

If it stops raining I will be able to check things out tomorrow - I will finish the blanking process (I made a new one to make up for the one I lost) and and see what happens. I have a new Map to upload to the ECU after that so ideally all will be fixed. If not I will see how having the good egrs connected actually works in the longer term.

I was able to complete the blanking without further issue - the gunk in the inlet system was quite thick as expected.

I then cleared codes using my faultmate which cleared the engine management light (EML) but the codes remained logged and the EML soon came back.

I cleared the codes again to get the EML off – I then uploaded the Test Map (original map modified to hopefully switch off the EML on the blanked engine). – before starting I tried to clear the codes (EGR Sensor A and EGR Sensor C) but they remained. I went for a drive but the EML light came back on

. So it would appear the Test Map will not switch off the EML on my now blanked engine.

I unplugged the old EGRs and connected the new EGRs which immediately cleared the EML without having to clear codes - I cleared the codes and went for a long drive and as before - all went well, no EML and no codes.

I have sent this information back to Bell Auto Services (BAS) to review and am waiting a response.

From my experience with this, it looks as if the engine can be blanked as long as the EGRs are working. If a software solution cannot be found and if they were easy to get to, I would remove the old EGRs, blank the new EGRs on the exhaust side so no gases get into them and install the new ones.

As an alternative I could formalise my temporary setup by mounting the new EGRs at the rear of the engine or in the drivers side battery box and run a wiring loom from the EGR connectors. Unfortunately no one sells the EGR style connectors locally so if anyone knows where I could get these I could get two cables made up - I believe there is a loom maker in Melbourne who can do this but I am not sure who they are.

I will let you know how the EGR remapping goes.
