This noise sounds very bad. :shock: It is not from injector - noise is still exactly the same during fuel injection and without.

First try to check valves "keyboard" in cylinder head - maybe one self-controller in valve rocker is broken and valve is knocking.

In my 2,0 tdci I had the same sound - sometimes louder, sometimes silently. I was sure for 100% that valve is knocking. I replaced 8 valve rockers - without effect... But as a result my engine... exploded on highway (broken connecting rod pan) - now I have second one engine...
