Glow Plug Problem

[Greystoke]

Hi,

After running Star Diag on my 06 ML320 CDI W164, Star reported this error:

2270-004 N14/3 (Glow time output stage).
At least one of the glow plugs is not actuated.

How can I find out which plug/plugs or faulty.

Thanks.

Can you disconnect the wiring and do a resistance test to earth? Don't know what the value should be but I suspect you'll find one (maybe two?) with drastically different readings.

Surely STAR should report which plug is duff? That's all my dealer did to ID the failed plug

Can anyone tell me where in star I can individually test each glow plug.
