Need Help!!! Lean code. HPFP low Random misfire issue and pump stops when filling up
Hi. i have a 2013 bmw 750li. I am receiving the following codes:
191E08 Tank Ventilation System 2 Malfunction. 11A102 High Pressure Fuel Pressure 2 Plausibility Pressure too low 118501 Mixture Control 2 Fuel Air Mixture too Lean Large Deviation 118401 Mixture Control Fuel Air Mixture too Lean Large Deviation If I let the car stay on longer I eventually get misfire codes. This gas pump stops often when trying to fill up gas. I have a random intermittent issue with this where sometimes ill start the car and itll misfire and then eventually stall from idle. However this happens on some start ups not all the time. Once i clear code problem goes away until it happens again. Car doesnt have issue during driving. Only during random start ups. When the car is running fine, I have full power no issues whatsoever. I have changed the HPFP, Tank vent valve, Leak Detection pump and some breather hoses for the vent valves. Any advice? Im not sure if this could be a DME problem or other electrical problem. I also have SVT code for my power steering : 482D01 SVT Voltage Supply Overvoltage Switch Off Steering Servo 482D07 SVT Servo Valve Short Circuit between positive or negative lead and terminal 30 Battery+ 482D0E SVT ECO Valve Short Circuit between positive or negative lead and terminal 30 Battery+ Occasionally i get a charge air cooling code after heavy aggressive driving: 20A202 Charge Air Cooling System Reduced Power Output: Coolant Pump Supply Voltage too low Last edited by mosaiham; 01-04-2024 at 11:32 PM.. |

Sounds like the charcoal vent filter is shot.
If raw gas got in to that filter from overfilling the tank after the gas pump nozzle shut off it will turn the granulated charcoal inside the filter in to a solid lump blocking the tank from venting the vacuum created by the fuel pump sucking out fuel. Remove the gas cap and see if it runs. Happened to me once on an E28 325i. |
