What is the actual problem; it may simply not be cold enough for the plugs to activate. Unlike earlier glow systems, these only come on at low temperatures.

No Vivaro-specific data to hand; but many common-rails tend not to use plugs for pre-glow above about 10C coolant temp. Are you getting post-glow heating? Is there a feed to the coolant heaters? Are all the Maxi fuses [particulary any 60+ amp ones] in good condition?

If there is a glow-plug system fault; then there should be a specific code stored in the engine ECU's fault memory.
