If i find out this afternoon that i need a new ecu for my 2001 CDT 75, do i have to buy a brandnew one from rover for £914 ?
Or can i buy a second hand ecu and have it recoded to my car by the dealers ?

I'm guessing not.. but i'd appreciate your info.

Glad you replied to that one keith :)
We didnt get a 12 page thread from not needing a new ECU

But just incase you cant be bothered to read it.. Its locked in "Programming Mode" and thats just one reason.

Sorry, I'm not following all the ins and outs and don't know the first thing about ecu 'complications'. However there is a fairly clever ecu 'doctor' who can repair most faults which may be a much cheaper alternative to a new one. His details are on the site somewhere.

Alan,

The saga is still ongoing.
The dealer have now replaced two diesel pumps and the problem stil exists.
The mechanic working on the car still swears blind that its the ECU causing the problem. The high pressure pump just comes and goes as it feels like it.
I'm waiting for them to confirm one way or the other.

No, just limiting too many more perhaps incorrect suggestions as this problem is getting potentially expensive.

I was happy to help clarify the pumps were not working because they were not being turned on but as to the cause then I was out of my depth.

It could be the ECU or as a result of something else telling the ECU not to turn them on maybe related to the imobilser as you first thought or maybe some other engine management sensor.

What I never bought in to was the garages suggestion that you needed to fit new pumps.

I am also still very suspicious that one of the garages has been responsible for killing your ECU as you seem to have gone from a intermittent warm starting problem to a completely knackered car.

It could of course simply be that the ECU was initially flaky and has now permanently failed, if so a new or repaired ECU will obviously fix the problem in the end

The only grey area now is has the work done to date to 'fix' the ECU complicated things?
