2018年10月8日 · The 2AAF is usually associated with the LPFP. If you are getting a HPFP code, you could be starving the HPFP of fuel with a faulty LPFP. You would need to check the pressure of both LPFP and HPFP.

The fault code 2AAF (if stored alone, or without any other faults related to the low fuel pressure system) is caused by DME diagnostic sensitivity, and should not be considered an indication of low pressure system malfunction. Do not replace the low pressure system components (e.g., EKP module, pressure sensor, electric fuel pump or filter) in

2012年12月10日 · The 2AAF in and of itself is not a HPFP code nor is it specific to tuned cars...as it is thrown on completely stock cars as well. Here's some good info on 2AAF. But basically if it does not cause drivability issues or is not thrown with other codes, then BMWNA's stance is that it …

2018年6月7日 · I've been having the 2AAF Fuel Pump Plausibility code coming up for quite a while now. I've researched this code and pretty much everyone says don't worry about it unless you have another code with it as well.

In this entry – everything, you have to know regarding fuel supply. Refers to all BMW engines with direct injection, specific parameters – to N43/N53. N43/N53 has two fuel pumps: HPFP (high-pressure fuel pump) – placed in the motor room, with chain drive from the engine. LPFP performs following functions:

2023年8月25日 · Decode the 2AAF BMW code and tackle fuel pressure issues effectively. Understand symptoms, causes, diagnostics, and more!

2019年3月9日 · 2AAF - Fuel pump; plausibility- Intermittent . 2AAE - Fuel pump - Intermittent But the car runs great. I have even monitored the fuel pressure, Low pressure pump is Feeding the HPFP with ~5000hPa , and the rail pressure is ~200,000hPa . Back in 2016 the previous owner got the HPFP replaced and NOX sensor and coils.

2020年7月18日 · According to DTC codes, it seems the low pressure pump in the fuel tank is faulty. Could some confirm it? N53, 530xi (Europe). Thank you! Generic readers give generic codes. You can go to newtis. info and research for a test plan. What symptoms did the vehicle have last week before it died today and left you the side of the road?

2022年7月30日 · 2AAF DME:Fuel Pump, plausibility. 2FDB Crankshaft Sensor, signal: not plausible. I checked the forums up and down, found some threads but nothing solid. Any idea what these shadow codes mean? _____

2019年7月10日 · Der Fehler "2AAF Kraftstoffpumpe Plausibilität" ist auch mit dabei. Laut BMW geht weder die Pumpe noch das Steuergerät kaputt. Was würdet ihr noch im Zusammenhang mit dem Kraftstoff, das der Fehlerspeicher nicht meldet, in Betracht ziehen?
