Peugeot Fault code

[Welshy_Pete]

My peugeot 306 hdi coming up with a fault code P0380

Glow plug / Heater
Circuit A

So is this the glow plugs need changing or the heater relay for the glow plugs?

Does this show which one is circuit A?

The last time it was cold the car was misfiring a bit on startup harder to start also a bit of smoke then clears up. So I had an idea this was a problem. But its only just started showing up 12 months later on the fault code but no engine light on as yet. The glow plug heater light comes on when cold only. This warm weather the car starts fine at the moment.

Thanks
