‘Engine Fault’ - DS3 BlueHDi 100

[Littleirwin]

Hi all,

I just bought a 2017 DS3 yesterday with 11000km on the clock. I drove it home 450km and the engine management light came on about 5km away from home, with a message on the touchscreen saying ‘engine fault’. The engine management light on the dash is constant, according to the handbook this indicates an emissions fault. The car is still under warranty but Citroen can’t look at it for nearly a week. The car drives normally, no loss of power. Does anyone have any idea what the issue could be? Could it be low adblue levels and does anyone know what warnings there’d be for low adblue levels?

Thanks in advance!

Welcome to the Club

It could be a choice of many things, only way to find out is plug in a diagnostics tool and see what fault codes come up

Could be DPF, could be O2 sensors, fuelling issue ...……

What I have read, if its adblue another light comes on the screen

With fault lights, its always best to get a decent diagnosis

Assume you checked the oil and water, all the basic stuff before you bought?

When you’re low on Adblue an orange Urea light shows and a warning on the touch screen comes on every time you start the engine
