Thread: '03 D2 Td5 ECU faults cannot be cleared

On your ECU can you check the part number and if anything the version..

NNNxxxxx <- The one on the end
NNWxxxxx <- this ones on top of the ECU usually

I'll investigate if the mapping is wrong for the unit and causing the errors, but we'll solve it...

Hi Kelvin, Phil told me of your drama.

We had a similar problem, what we did was reload a standard file over the one with the faults, clear the faults on that file go for a drive to make sure it drove OK, CHECK FOR FAULTS, all OK, then reload the upgrade over the standard file, seems to have worked so far, maybe try a different file, Phil has a couple I think.

edit, disregard my ramblings, Phil said he tried all that

Baz.

Thanks Baz. I don't think we loaded a standard map file....just loaded another that he had. The map that was on there had a weird name for the fuel map (from memory) and Phil recons it may have been corrupt.

Cheers

Sorry Caine, no idea where I got Kelvin from

I can't help with my standard file as my D2 is manual.

Hi Baz,

I was just checking if this thread had any updates and re-read. Are you saying above that the faults are associated with the file?

seen this on the busmasters....

if you have a fault in active memory when you write in the new map you may not be able to remove the fault codes. Reinstall the original map, clear the faults and then re-install the new map.

Dont know why, the techs cant explain why, it shouldnt do it but it does and just to make matters extra funky some readers will pick up the errors and some wont..

IIRC, the faults are registered into the memory and align themselves with the map. If the map is changed, the association with that map also changes and is not recognized by the new map either.
The new map won't overwrite this internal register as they aren't associated with the new map and as the faults are logged in order, it will only see the first visible faults from the old map first.

It may be worthwhile trying to get a fault to occur with the new map and see if it registers differently or actually logs the fault as the reader may only be programmed to look for one particular register set and not a secondary set from the new map. Kind of like a PC when it files things under say ***.reg and a previous as ***.old, but it only sees the .old file.

If not, reload the original, reset and reflash as per other posts.

Cheers

All of those faults normally indicate "oil in the harness"
You stated that you removed the ECU to flush it.
If you have oil at the red plug on the ECU you need to fit a new injector harness to start with,then look at flushing the oil from the main harness(metho spirits is good).EASY DIY JOB!!!!
The faults will go away as the oil goes.
GOODLUCK
