so a general update.
the high pressure fuel pump was changed... BUT
I've noticed that it is directly related to the gasoline used.
Costco and Esso 91 gas has a ridiculous knock... 94 Petro Canada doesn't.
I have a full gas of Esso 91 and it was ticking away like a mother *****...
The first time I noticed the noise was from 93 Shell...
I will try to go to Vpower once more after my whole tank is done and see what happens...

Reason: shall 93* instead of shell 91 as originally stated
