Scarab 2015, twin Rotax engine, code help

[Meloncholy88]

Hi all!
Well my 2015 I accidentally drove in heavy seaweed, burned a hole through the muffler. We welded it back together, it’s now having all these codes ever since then. It runs great, it’s never had an issue since I bought it new. I just had another mechanic shop that had the computer for Rotex hook it up. He was supposed to clear the codes, restart it then see what error codes are left. He didn’t but can anyone give me some insight on these? Engine misfires common, it’s two engines so two error codes at times.. I’m posting it as my mechanic is overwhelmed. Thanks for any help! Melanie

Definitely a lot of codes! lol Crap. He definitely should clear the codes first. Why didn't he? Some of those are definitely directly related to the weed problem such as the overheated exhaust. The intercooler is likely related too since it uses lake water to cool things down.

Also, are these ACTIVE codes or are they past ones? The system indicates that. The cylinder misfires for example would have nothing to do with the overheating exhaust. those are likely a bad spark plug. When were they last replaced?

O2 sensor is a common problem and likely unrelated as well. Easy fix and cheap. It also won't impact performance at all in this case since it's downstream.
