Troubleshooting?
What’s up guys, new to the forums!
I’m having a few issues with my 2016 m235i that I just can’t figure out and hoping for alittle help. The car is FBO with the fab speed exhaust all the way. Forge Motorsport BOV kit, JB4 tuner, BMS intake. I am running map 5 on the tuner. Etc... My issue is that when I’m driving the car it will jerk forward. I haven’t noticed a pattern to when it does so. It also feels like it has gotten weaker on the throttle. When I throw it in gear (2nd-4th) it sometimes has a weak throttle and if I give it gas it just starts backfiring out the back. Any help is greatly appreciated. I can answer any questions you guys have about the car. Last edited by Nicksoap; 05-24-2021 at 07:37 AM.. |

The first step in diagnosing a problem is to scan the engine computer (DME in BMWspeak) for codes. The Service Engine Soon (SES) light is on only when an emission related code is present. If the car has an automatic transmission its computer (EGS) will need to be scanned, also.

Highly doubt it has anything to do with brake pads. My rough uneducated guess would be spark plugs. Marco is right, you should do a scan so we are not guessing.

118002 Mixture control. Fuel air mixture too rich I get these codes when I run a test. I know the 102001 is due to my BMS intake and the MAF sensor not being a good mix together (ordered a CTS Turbo intake just waiting for it to be delivered) Not sure about the mixture control one tho? |

Try cleaning the MAF sensor too and also check and tighten as needed all the connections of the intake and chargepipe if you have one. |
