The summary is car wont start.
E46 318ti Compact 2003 with N42 engine.
When I turn on the ignition the temperature sensor goes to max and stays there. The car cranks but doesn't fire up.
I've installed INPA with a modified VAG com lead and also run BMW scan demo v 1.4. Neither can detect the DME. I'm getting IFH-0009 from INPA when I try to run engine diagnostic. Other modules are accessible: DSC, radio etc.
I'm going to install DIS v44 and see if that tells me anything more but expectations are low.
The car has previously fried another DME so I suspect it may have done the same again.
Any thoughts on how to proceed most welcome.
Also looking for service manuals for E46 compact.
