P3Car Gauge

TB///M3 · 11-21-2014, 04:04 PM

I received a P0420 Fault code it's likely due to me having a non catted down pipe. I thought the P3Car can clear this code, but it seems like it doesn't.

Anyone else having this problem?

Does the P3 clear codes? I don't remember hearing that before.

Clr.C in the config mode will clear codes but it's only one time, not active. So if you drive another 10 miles and the ecu throws another one of those codes due to the catless downpipe, you have to clear it again.
