Sorry to hear that. One of the most common causes of this fault code are unmetered air leaks. One of the most common spots for an air leak is right where the fresh air pipe goes into the turbo.

Hello, I just changed my hpfp back to oem. Could that be the reason I have the code? So should I just unplug the purge valve and idle for 15 mins?

[@AskTheCarExperts]

Changing to an OEM HPFP should not cause this code. An air leak or if there is any drag on the engine this code can set. In some cases the HPFP can cause some drag or a problem with the cylinder head. But to do the purge valve adaptation reset. Clear the engine adaptations with a scan tool. Then disconnect the purge valve so it cannot activate at idle which would richen the air mixture. Then idle for 15 minutes. Clear the codes and recheck.

Just last month I notices that the boost pipe (which goes out from the intercooler to the charge pipe, and then to the throttle body) Wasn’t attached properly to the IC. Also the inner seal was so loose inside that air escaped out of the pipe: hence rich condition, since measured air escaped out of the pipe and thus less air entered in the intake manifold.

Great video, thank you. I have a 2011 BMW X25 N55 ... and this damned fault code is a real pain in the a...ss. Have been chasing it since 6 months. I have replaced so many parts and I am very frustrated. When I start the car, cold or hot, it will rev up itself to 1500 rpm, then go back to 1000 rpm and then gradually down to 650. The idle needle is stable but I feel rough idle on my seat, intermittent vibration. When chcking N55 start up on youtube, it seems that mine is not so normal (rev to 1500 and go down) CEL is ON. Fault code is 101F01. I have done the idle procedure countless times, but the fault code will come back everytime. I have replaced so many parts...Spark plugs, ignition coils, turbo inlet pipe, turbo outler pipe, intercooler, charge pipe, TMAP sensor, Hotfilm MAF sensor, intake manifold gasket, throttle body, puge valve)... The only light in the dark tunnel I have seen is that one day, after disconnecting purge valve, I cleared the code and I did not reconnect the purge valve electrical connector, I drove the car like that for 3 days. I put my ISTA-D the 3rd day and checked but the 101F01 code did not show up for those 3 days. I had CEL ON but it was because the purge valve was disconnected (tank vent disconnected). So I think my problem may be on the Evap side, because when I isolate it, the code wanish. When I check on ISTA, with tank vent connected, I can see several occurences at different speed, rpm and times of this 101F01 code. I believe it follows normal purge valve operation openings and closing during driving; I don't have smoke machine unfortunately to check tank vent system for leaks. But I suspect that my problem maybe on the tank side. There is no fuel smell in vehicle, I can fill my tank full with problem. Any suggestion welcomed

That would be an interesting failure for this code. You can remove the TVV and see if it is closed correctly by blowing through it. At this point I would replace it and recheck since that seemed to make a difference.

Hello Sebatsian, I would be happy to give my thoughts on these codes. Air mass issue - smoke test the intake. Air leaks are common at the crankcase hoses and the fresh air intake pipes to the turbos. Rail pressure sensor stuck -- replace the sensor. High pressure plausibility - do the sensor first and recheck. High pressure pumps are also common to fail. Cat efficiency fault - failed CAT often due to leaking injectors. If you find a broken down CAT via inspection via borescope replace the injectors as well as the cat on that bank.

Ещё версия есть . Нужна хорошая притирка посадочных мест клапанов

Interesting. I have not heard of the valve seats causing this issue.
