3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
I get P1470 error code on my 2000 323i. Any suggestions?
Autozone gives P1470. I paid $100 at a BMW-shop and get codes
246=F6 Flow rate,secondary air system, too low, bank 2.
245=F5 Flow rate,secondary air system, too low, bank 1.
126=7E solenoid valve.Tank leak diagnosis pump, activation.
In addition: Outside air temperature sensor is missing.
The last makes sense because the OAT shows -40F
The shop seems to think that all I should do is replace the Temp sensor, but I am afraid the real problem is the 126=7E error
246-F5 & 246-F6 code - when you get these 2 codes same time, your first line of suspect is the airfilter of the secondary air pump. change that and make sure the air lines are clean, and you'll be fine.
secondary air pump is by the left of the firewall, when u stand infront of ur car looking at the engine bay.
OAT sensor.... that is connected in the front bumper area. Not related to the above codes
