In the plenum chamber below the wipers.

I've sourced a replacement - are the ECUs locked to certain cars? Or can they be swapped? I've ordered the ECU at 99 + delivery etc. - seemed too good! What about the white box next to the ECU?

Engine ECU must be brand new if you can't get yours repaired you can not fit a second hand one
It must be coded on Testbook to the car
The little White box if yours is a diesel is the Glow plug relay well worth taking the top off to see what state the contacts are in

Hi,

I have a post here from yesterday, " Rover 75 diesel, Died".

I've just had the diagnosis from DTM in Bristol. The ECU has failed. There was water on it too, though not that much according to the RAC man who looked at it and tried to dry it out.

Apparently it's going to cost me 230+VAT to fix/refurbish.

Regards,

Kalvyn

I've tried a working used ecu and it doesn't work. I think it's the white glow plug relay box... anyone? Does anyone have the circuit diagram for this part? It's labelled PA-GF30.

It's not likely to be the glow plug relay as this has no bearing on starting the car.

The ECU MUST be new or it will not work. The security chip is located in the drivers footwell and this must be matched to the ECU or the same problem will appear.

Get a new ECU and it can be programmed to the EWS (security) chip and all will be well.

Even matching a used ECU with its EWS chip is still likely to cause problems so imo, bite the bullet and find yourself a new ECU and get your dealer to programme it.

I agree with Mark in warm weather Glow plug heating really should not be needed to start the car it might churn over a couple of seconds longer but should start so I doubt if the glow plug relay is the cause

They do however disintegrate, pop the plastic top off and if the contacts are shot replace it anyway either with a good secondhand one or new

You may find the new ones although a direct fit are bigger and appear to have two extra contacts as they are also used on the 6 cylinder BMW engines

(I think Andrewmsteve told me that when he gave me his old one)

Hi Andrew are you still well?
Is the new IPK I set up behaving itself?
