Had a diesel leak under the bonnet pipe not fitted properly now fixed cleaned up diesel but diesel smell still in side car what’s the best way to clean engine bay of diesel remnants 

I would try using TFR and other degreasers then hit it with a jetwash.
I think most of it may be not easily accessible as on the underside of the engine and on top of the undertray which will make it difficult to clean unless you drop the tray down

Pollen filter replaced now smelling good
