Hello,
my 2011 Audi A3 has had an issue with code p2568 (direct ozone catalyst temp sensor) which I’ve been told that it has to do with the sensor mounted on the radiator so I’ve switched out the radiator since they don’t just sell the sensor drove the car for about two weeks and the CEL came back on with the same code I’ve since cleared the light but still registered on the permanent codes the think I can’t figure out is after I drive it for a day or two the code comes off the permanent screen and the car will be fine for a couple weeks before it repeats the cycle do you have any idea what it might be?

The catalst coating on the radiator isn't reaching operating temperature quickly enough.
Replace the thermostat.
