Ive never personally seen a knock sensor go bad, but im sure it happens.
I missed in the reading: have you tested resistance between your signal wire and ground?
AKA- take the plug off each sensor, and probe the terminal inside against a good ground.
If there is continuity, that means that...
Was the 3mm head gasket necessary for material removed from the deck surface? I would think if you were to use too thick of a head gasket, it will pull cam timing off slightly, due to the taller height between crank and cams.
Code 52 will cause a limp mode situation, since the knock detect system is compromised, and thus the engine will adjust to avoid potential knock. Not sure if this includes retarded timing, over fueling, or both.
Might want to try posting this in the MkIII "wanted to buy" section instead.
As for part number, you can try 781801B040
But it all depends if you are 5 spd or auto. You never said.
These fuel filters do accumulate dirt over time. I cut mine open, which had approximately 50,000 miles. 8ft long, and unfolded, you can see that the outer edges(which are together when the element is folded), are the only remaining full flow section.The non-translucent section is literally caked...
Well, I took an old TEMS switch unit, popped out the guts, glued on a new ABS grainy plastic face, and fitted a rocker switch for my cutout. Looks pretty good, and of course, fills the spot as it should.
If you don't mind cutting the shifter surround, you could place either style plug just above and to the right of the shifter hole.
Otherwise, just hide the plug under the armrest.

Original part number on my maroon is 55441-14100, and shows as discontinued.
But there is a replacement number, 55441-14101, and you may still be able to get it.
It says that this part number supersedes the following:
55441-14100-02, 55441-14100-03, 55441-14100-04...
I PM'd Cthulu, asking him to give updates.
I hate unresolved threads. If results aren't posted in the threads, there's no point to using the search function,
and that's why we end up with multiple threads on the same topics, and we're always yelling at people to use search.
Hey Cartert,
Glad you figured out the issue, and it wasn't the cams/ crank pulley.
I would continue to check all of the vac and boost hoses/ pipes for leaks.
