Rover 600 Turbo Diesel Ecu - johnat23
Help... Diesel injection pumps used to be contolled by rods and visible thngs! Am I right in thinking that all functions of a pump are now controlled by an Ecu, and any faults are only repairable by someone with the software/reader etc to read the faults. My Rover 600 Diesel runs beatifully most of the time but just recently has started to almost stall on roundabouts etc and the yellow engine warning light comes on., then it will pick up again and run for a day or so without occyuring again... Any ideas ?

Not likely to be the ECU. They are generally very reliable.
More likely to be a conection to one of the sensors . Check all the engine sensor connectors for corosion or loose cables, give the electrical pins a spray of WD40.

Yes, I agree - most likely a sensor or connection issue. ECU failure is very very rare - and mostly only seen when careless jump-starting has taken place.

The brake pedal switch requires accurate adjustment, this might be a contributory factor.

You need specialist software & hardware to interpret the system.
Find a Bosch Diesel service centre - they'll be able to sort it for you. Having the fault light come on is actually a good thing - it means a fault has been recognised and logged, which should aid diagnosis & final rectification.
