New o2 Sensors, Resetting ECU (limp mode?)
So I just bought a C5 (A6 Avant) and I needed to replace the cats and o2 sensors. Magnaflow cats are already in and I'm replacing the o2 sensors tonight, but what method should I use to reset the ECU? There are so many on the forums, but folks are warning about the battery method because of limp mode. I actually just replaced my battery, and didn't really notice anything different? Is my car IN limp mode now? How would I know?
I don't have a vag com, and I'd prefer not to go back to the shop, but will the battery ecu reset clear the settings/cel well enough?
