Recently come back to the fold and found a nice 2002 TD5 GS with 85k miles and one owner from new, loving it really .. but...
was fine (if damn slow) but after a run on a dual carriageway it started throwing a white smokescreen out when pottering around or at idle when warm. Friends diagnosed a turbo so i fitted a brand new Garrett unit and my smoke dropped to hardly anything or the odd big puff which I put down to the intercooler needing clearing out . Crawling out of the shopping centre two weeks later Ive caused chaos with so much smoke one day I was shrinking in the drivers seat and this morning crawling through traffic it was terrible.
Just read the error codes and I have:
Injector 1 Open Circuit Detected Logged
Can Error Fault Currently active
Injector 1 peak Charge Long Logged
Airflow Circuit Fault Logged High
Aircon Fan Drive open load fault.

Al have cleared fine.

So I will drive around a bit and recheck faults as some could be ancient.

Water levels are fine, temp is fine, not suspecting any coolant/headgasket issues

The car seems sluggish - certainly less go than my last facelift disco but this is 20 years later so I'm not expecting it to go as well.

The smoke is the issue... any thoughts? I'll repost here when Ive checked the fault codes again after a drive.

Thanks.

Is it automatic?

Check the ECU red plug for oil. Unplug the MAF and see how it runs that way... the EGR is still in place?

Will check those thanks , yes EGR still in place

Manual, oil in red plug, cleaned out still the same. EGR still inplace, will google MAF location and look when I get home

you have to replace the injector loom ASAP http://www.discovery2.co.uk/Injector_harness.html, if you have a compatible scanner(not generic obd2) see live injector roughness, manifold pressure and inlet air temp readings

MAF is dead easy to find, connected between the air-filter holder and the hose going off to the turbo, just disconnect the plug.

thanks for replies, new injector loom installed , ECU cleaned up, wasnt a lot of oil around at all really . Still smokes like a smoke grenade. disconnected MAF sensor wiring and it makes no difference. Error code 'Can Error Fault Currently Active' has reappeared but nothing else.

That's specific for automatic ECUs as the manual doesnt have a CAN circuit... tell me what part number is on the ECU cos i have the feeling that the PO fitted a botched up automatic ECU then this can be the problem....btw what diagnostic tool you have?

just put it all back together and come insode so I'll remove the ECU looking for part number in morning when its daylight. Previous owner had it from new until he died earlier this year , has been maintained by his nephew a very well known (at least locally) land rover specialist whos fastidious so i cant see it having the wrong ECU. I have read that the code reader itself may give an error as its not a true ODB2 in the disco ? I have a Launch CRP123X which i use on works vans and have been very pleased with it
