I have printed off a copy and looked through.

It's pretty good.....BUT if you have an ECU failure or a Mil light on, it is a bit thin on trouble shooting help....I think.

The circuit diagram....I am using a Revue Technique Automobile manual....yes, it's in French....the diagram is awesome.

Can some expert write a guide in plain English, such as ...When you turn on the ignition, 12V goes to X via fuse Y to relay Z which then.....the ECU then signals....in response to sensor A.

If sensor P fails, or it's wiring fails, then the engine simply STOPS.....such as the camshaft sensor....or the crankshaft sensor.

These engines mechanically are very well proven......but the management system, and clear simple explanation let them down badly....just read the forums and people's experiences in garages , is hardly encouraging.

I've got that off my chest.....still broken down in Paris !?
