One very dark, very frosty night, it breathed its last, and I got towed to a local diesel/engine management specialist. He identified a relay under the glove box which had failed, and a suspect, slightly corroded ECU. He replaced the relay and cleaned the ECU up.

Now it goes perfectly again, but still very occasionally (I mean it can be weeks between incidents) takes two goes to start, or “blips” briefly while driving. I have to assume there’s some slight corrosion damage to the ECU.

Big Russ was enormously helpful when all this happened, and told me if I wanted to change the ECU, one way was to swap the little EPROM from mine to the replacement one. So I’m trying to buy a used ECU to try that with.

But… are you saying the map, including the 135bhp upgrade, is in the little EPROM too?

And what are the better options please!

Apart from an 800 mile round trip to Newcastle!

Thanks
Roger
Post the ecu to Brian he will test it ,if necessary, repair it and post it back to you.
If its u/s he can re programme a new one for you.
