Good afternoon all,

This vehicle suffers from a VERY loud diesel knock when cold, especially when pulling away, but no excessive smoking.
Once it warms up the engine is fine

Different fuels have been tried, Nissan are unaware of any issues or updates.

No dtc's are logged, using Google diagnostics there appears to be some discussion about this noise.

Its not a vehicle we see a lot of, has anyone experienced these issues ?

Regards Glyn
