X5 35 d throwing new codes
Hi everyone. Have a 2011 x5 35d with 169,000 mile s and thanks to this forum have been able to solve a ton of issues. Recently had dpf and egr issues and addressed both to success! Now a new monster has reared its head and I can’t find any info. Engine went into limp mode today (engine operating at reduced power) and just happened to have my Carley with me .... codes new to me;
04F6F - high torsional vibrations/error hydra;ic pump 004BD9 - injector cylinder 6 control Any idea or direction would be great;y appreciated😀 |
Not sure but I have a 2011 X5d so I read these threads with interest. At 138k miles, I've recently replaced the glow plugs and module, throttle/anti-shudder valve, engine coolant and transmission fluid thermostats, low-pressure EGR cooler, boost pressure sensor, EGR temperature sensor and MAFS. A couple of years ago at 118k miles ago, I replaced the active DEF tank, SCR dosing module and NOx sensors. Ive had no DPF issues to speak of.
Could it be a failed injector? Could the other code be a "knock" signal code? |
Injector 6 could be corroded. Read all of this thread https://xoutpost.com/bmw-sav-forums/...ne-dies-3.html

If you clear it, do both come back????

Injector 6 is dead or dying. I had the same codes 2 months ago

Just thinking out loud.... A diesel high pressure fuel pump, is running and pumping fluid under tremendous pressure into a dynamic system which has 6 'outlets' (fuel injectors) As it runs, at speed, you get a nice rhythmic pulsing- fluid enters, fluid exits...everything is happy. Pump spins... every 40 usec a pulse happens. But then one injector takes a crap. AS a result, the nice "every 40 usec" rhythm is interrupted. Does this result in a odd 'torsional vibration' in that fuel pump?? Id replace #6. :cool: |
