I have a 2008 Renault Megane 1.5 dci. The day before Christmas Eve when I was going home from work it came up with “ check injection” it behaved ok. The next day I went to start it and nothing it cranks over ok until I flatten the battery lol but it would not start.

Does anyone know what it could be? I’m thinking it’s one of the injections

I had a mate come round and he plug his computer in and it came up Glow Plug Relay Module
