Black exhaust smoke


Hello, I have a 2005 terios. It hasn't moved for a while due to the fact there is black exhaust smoke coming out the exhaust. I have ran an engine compression test and all the cylinders are within normal parameters. What do I do next?

Thanks Stuart

Black smoke is unburnt fuel,

Black smoke is unburnt fuel, so an injector or pump problem. Get it looked at by a diesel engine specialist.

Alternatively, could be a bit pricey if wrong guess first time, remove all four injectors and send them away for reconditioning.
