help with reading codes

ady9 · 08-24-2014, 08:09 AM

hey guys i just recently put catless DPs into the car. ive read that you can sometimes get a code because of it. Ive been told you can buy a DP fix or if you have a jb4 it will automatically do it for you. ive driven the car say for 50kms and no problems but today when i got on the freeway i got the CEL engine fault decreased power. pulled over restart the car and it was fine but moments later the check engine light icon came on and stayed on.

codes im getting are
29F4
29F5
now these 2 codes i believe got to do with the catalyst system so my 02 sensors arent liking it. the only thing im worried about is that the mechanic may have mixed up the front and rear 02 sensors? how do i check this? im bringing the car back on tuesday to get it sused out but what happens if you do mix up the 02 sensors?
A287
3100
now these 2 codes i dont know why i have these. first code is exhaust vanos mechanism and the second code is boost pressure control deactivation boost pressure build up prohibited
now this one im scared that mechanic had installed it and the v band bolt may be in the way of the actuator. but ive pushed the car a bit when i got it and it seems like its getting boost.
i went to a mates place and cleared the codes and got some coding done. thanks brah, he turned on auto disable codes but i turned it back off later to see if i chuck the same codes. drove the car around no CEL but i read the codes when i got one and im getting the first 2 codes. the other 2 codes havent come up yet. i guess if they do come up i would have to take out both vanos solenoids and clean them before thinking of replacing them.

anybody let me know if anything is wrong? anything i should be worried about? im sure its fine, but being a 335i owner i think this shit always happens to us when we start modding. need closure and reassurance ! so gurus help me !

EDIT: yes i do currently have jb4
"auto clear code" is the jb4 dp fix ???

Boost pressure deactivation is cause by the VANOS fault.
