[Engine] 2.0 Hdi siemens injector resistance

[Mark Glaister]

does anyone know the expected resistance across the electrical socket terminals (where the plug goes) on the top of the actual injector on a 2.0 Hdi 2003 berlingo running Siemens engine management?

I've got approximately 200k Ohms across all but one injector......the odd one is approximately 150K Ohms.

Thanks in advance
