Hi guys i didnt drive my car (f30 335i) from around 2 months cuz i bought other ,anyway today i want to have some fun with rwd and when i start the car saw the check engine light didnt disappear ,so i checked whats goin on trough my bm3 platform and i have 12B304 lambda probe heating after catalyst activation: line break.So i add it in the map config and flash ,the code was gone but when restart the car it pops up again.CEL is of and i add this to the list but still there wtf?what i can do about that do u think there can be some problem with the lambda?The car runs normal though.Its bm3 st2 with catless vrsf dp.Give me some thoughts pls

yokata,

Check your O2 sensor wiring. Perhaps a roden got into your engine bay and did some damage.
