TD5 ECU Problem
Good Morning.

I wonder if anyone could help me with this.

I had to purchase a new ECU for my 1999 90 TD5. I rang my local main dealer Hunters in southampton gave them the reg no and they sent me the new ECU. I fitted it and got my local garage (on the isle of wight) to reprogram the injector codes and the immobiliser. I got it back last friday but the temperature gage reads wrong. When it is cold the gauge reads about 3/4 the way up (hot) and when it warms up it goes down into the blue (cold)

any ideas.

thanks

jonathon.

Hello,

Sounds like it is an ECU for a discovery, you cannot buy early type ecu new anymore. If it is a later type ecu then it will need reprogramming with an EU2 map for a defender.

This is the limit of my knowledge I am afraid, post up the number of the ecu. Someone will be here shortly to tell you exactly what needs doing.

They have only programed the injector codes and learnt the security, they need to reprogram the ecu calibration to match the old EU2 engine for the Defender and not the later EU3 discovery which is a factory installed calibration on a new ecu.


In a nut shell they have only done half a job Confused

Assuming you have now got a NNN500020 ecu it will need a calibration like,

NNW501340
STHLE 022 STTLP 010 European
Defender 90 No Aircon

Really not sure. I'm not sure what it does in the programing of the ecu. A nanocom will do it if you have acess to one.
