Santi had a good idea. Louis needs to buy a Peake reader and keep it in the car. The next time he gets a CEL he needs to immediately pull over and check the codes. That way, he is more likely to find the code that is the culprit, rather than a bunch of latent legacy codes.
The CATs on the car are BMW. They have been replaced. Santi checked the welds and didn't see any signs of exhaust leaks. One of the O2 sensors did tighten a little, but wasn't loose.
Repacing the O2 sensors is the first order of business. I'd like the give the Indie the benefit of the doubt and believe the original CATs needed replacement, but it's hard to do that when they didn't replace the O2 sensors with the CATs. Makes you wonder, although Louis still thinks highly of them.
