Is there power to the glow plugs

Have heard a few reports of the glow plug relay failing. This lives in the front right corner of the engine bay tucked away so that you have to reach around the battery.

yes there is power to the glow plugs

It might be a dirty MAFS reading the incoming air incorrectly, or a dirty SCV. When warm, does the engine "hunt" around at idle, varying the idle speed by a noticeable amount? If it does, run a can of Liqui Moly Fuel System Treatment (about $25 at SCA) through a tank and see what happens.

I,ve had one where relays have played up and caused it to miss and rattle. Replaced fuse box under the bonnet and problem solved. Had happen on both petrol and deisel. Hope that might help.
