3... 3 rpm, holy smoke balls, I could crank it over faster than that manually with my wrench 🤣 Are you sure?

Well that's not a DTC. DTC's start with a letter (specifically a P, C, B or U) followed by four numeric digits.

You need to get a proper code reader. Get an ODBLink Ex, or VGate vLinker, or a cheap ELM327 based one with the MSCAN switch hack, and the free ForScan software (for Windows). That'll allow you to get actual codes that could yield some helpful clues.

However, since yours is a Mk2 and you're suffering from malfunction errors and limp mode and such, there's a possibility that you might be suffering from the classic solder joint issue on the instrument cluster's wiring connector. See links below in my signature for my own repair service for this. There are a couple of things that can help suggest that this is the problem, one is to thump the dash above the IC and see if this has an affect, and the other is to check resistance across pins 6 & 14 of the OBD2/DLC connector when the problem is occurring, it should be 60 ohms but if it's 120 ohms that confirms a problem.

Edit: My response was rushed a bit due to wanting to watch a TV program. Actually less certain now it could be the solder issue upon re-reading.
