General Noise that appears between 1500 RPM and 2000RPM

The offending cooling hose has been replaced and the noise is now gone. Apparently inside this hose is a small ball that was rattling causing this odd noise once the engine warmed up. It only affected some Grendiers and a new part number replaces this older version. I am so happy now that i can just hear the growl of the diesel

Hi there. Was the noise between 1500 and 2000rpm in neutral (revving engine) or only under load?

Under load and after the Grenadier had warmed up.

I also had the exact same issue, they ordered the part which on my print out from them says de-gassing hose and said the BMW part has a piece inside not needed on the Ineos and once replaced I haven’t had an issue since.
