Disco 2 Faults appearing

Hi folks

I have an old Hawkeye diagnostic. I tend to connect it to my Disco 2 TD5 every couple of weeks just to check if any faults (DTCs) have appeared (as a preventative measure).

Today, I decided to connect it as the 'sound' the engine was making seemed slightly unusual. Despite this the car performed well on the motorway (I do around 100 miles every day on the motorway).

I found the following faults logged in the EMS that I had never before seen:
(Fault 3016 - Inlet air temperature high fault logged)


I went into the 'Live Data' section to find out what the system thinks the inlet air temperature is (engine off). It recorded 61.9 degrees:



I also noticed two further faults logged (code 3213 and 3215) for Injector Open Circuit (injectors 1 and 3):




Any ideas if these are all linked? What should I do first (without loading a parts cannon!)?

Thanks
Mark

clear the faults and go for a drive and retest

All those faults can be the result of oil in the ECU red plug which if it's the case you have to change the injector loom

I just checked now....but the plugs are clean. Not a spec of oil. The loom was replaced a couple of years ago.

I have cleared all the DTCs. I have to drive to Manchester and back tomorrow...so I will check it again after about 90 miles of mostly motorway driving and see if anything new is logged.

It's possibe that the codes were hystorical logged before the loom was changed?

No. As I mentioned in my original post above, I plug the diagnostic in every 2 weeks regularly. They weren't there two weeks ago.

Then IMO the oil ingress in the loom has started but didnt reach the ECU yet, eventually check the upper plug which connects to the head for oil.... do you still have EGR?

Hmmmm.. I just checked it again after having done 90 miles today. No faults logged.
I deleted the EGR a couple of years ago with a blanking kit.
I wonder if pulling (and then reconnecting) loom connectors helped to fix it?
I think all I can do is monitor the ECU plug as you suggest and check for stored faults every couple of days.
It's MOT time in a week, so I don't want to fiddle with it too much.

Some eletric contact spray in the plug would be a good ideea then

Time for a new loom then
