Right so I was driving to work as you do and suddenly my eml come on I was like Hmm (most cases it's Throttle position sensor or fuel pump primary circuit and it cuts out) but it didn't this time and like it went into limp mode I pulled over and it was knocking really bad. Turned it off quickly chucked my diagnostics on and had 3 codes. Po230 fuel pump primary circuit...... But... Here's the weird bit. That code came up 3 times. On the same fault.... Cleared it then it was fine... I'm Confused lol.

I've never seen this before, but I would hazard a guess to something like an injector sticking open if it was knocking a lot.... Keep an eye on it and maybe run some live data to check everything is running properly.
