2011 335d Fuel Issue, Help!!
Hey guys, here's my situation:
Fully stock, 80k mile 2011 335d Issue: "Rail pressue plausibility quantitative control" - code present since I purchased car on March 27th; went into limp mode 40min into drive home, threw that code and a throttle code. Have since put over 3,000mi on it. Have had it at 3 different shops including one of the local BMW dealerships. Have replaced nearly the entire fuel system. Cannot get it to stop throwing that code/going into limp mode, all of us are stumped. Parts replaced: New Fuel Filter New BOSCH OEM High Pressure Fuel Pump (came with Quantitative Control Valve so that is new as well) New Genuine BMW Fuel Pressure Sensor (front of fuel rail) New BOSCH OEM Fuel Pressure Regulator (back of fuel rail) New throttlebody New intake manifold gaskets (6 and 6) Full carbon cleaning done New JBE (junction box) and full software update through ISTA to current software version for all modules as per current TSBs Low pressure fuel pump has been tested and found to be working properly as far as I know. Correct fuel pressure present at HPFP from LPFP as far as I know. No leaks in system have been found to my knowledge. No fuel injector codes, or any other codes of any kind for that matter other than the rail pressure code mentioned above have occurred before or since I replaced the throttle and that cleared that code up. Has never thrown an injector or misfire code. Vehicle will sometimes drive for several miles before it goes into limp mode, sometimes limp mode will occur a few seconds after starting the vehicle, sometimes it will occur if the vehicle sits idling for a while; always throws a CEL and the rail pressure code. Any advice/diag would be extremely appreciated at this point!! |

Hey,
I'm having an exact same issue, see my post here: https://www.e90post.com/forums/showt...9#post26501799 I found literally 5-6 posts with exact same symptoms but most people don't end up resolving this. Hope we can figure it out together, as this code is my worst enemy right now.. |
