Have an oil leak coming from the head loom and oil has reached the cpu, TD5 110 (year 2000)
a new unit is very expensive, over £2000, and spares are few and far between, can i use a used
re-wrietable unit from a TD5 Discovery ?
 
Saw this before which explains all well in the thread

I recently had some problems and I discovered that the TD5 engine with the 15p serial number uses the later NNN000120 ECU which can be flash programmed with a new map, mine has this and was one of the first it was registered in November 2001.
These are also on the discovery 15P engines with manual transmission
The Disco TD5 15P with auto transmission has a different ECU

The 10P S/N engines use the older type MSB000080 ECU this cannot be re mapped, but I think there are people who will program an eprom and use this to program the ECU by soldering it onto the board in place of the original.
I believe this ECU has the standard 10P map in it.
As far as I understand both can be read by Nanocom but not by standard OBD2 readers as the configuration is non standard.
Now I am not sure and it will be best to verify but I think the newer ECU can be fitted on the older engine,
 
Thank you Jimsky
I beleive my landy has the 10P type, so I'm waiting to see what the garage says !
fingers crossed
thanks
 

as bankz5152 says a £40 fix ,, FIO ...the 10p used the msb series which the later 15p (around 2002) used the nnn series cpu, I have used the msb on a 15p with no problems I currently have a 15p (2001 defender 110) and use the nnn progamable I think it came from a discovery (the water temp gauge runs in reverse)
I did have to re programme the injector codes , the accelerator pot , and immobaliser tho, but this is easy if you or someone you know has a nanocom.

 
Just to say ,, this is a common fault with early td5s it can result in all sorts of weird symptoms .. and is usually as said a £40 good as new fix
