The most common signs of bad mass air flow sensor (MAF) in BMW X3 are loss of power or slow acceleration, engine hesitation or jerking during acceleration, erratic idling, misfires, poor exhaust emission values and sometimes black smoke comes out of the tailpipe. The mass air flow sensor is part of the engine’s intake system and is located
I’ll dig up more info (schematic) later today. The MAF is wired to the DME, there is a fuse in the 12 volt line that powers the MAF. However this F3 fuse in the DME box also powers the cam sensors, the crank sensor, and the t-stat heater. I suspect your BlueStreak is the problem.
One of these components is called the Mass Air Flow (MAF) Sensor, and it is perhaps the most crucial element in a car’s electrical fuel injection system. If something were to go wrong, it could result in serious problems. Bad MAF Sensor symptoms include rough idling, loss of power while accelerating, starting trouble, and more.

SAP mini MAF code. you should be good if this code is not showing up for the SAP mini MAF.The code number P2430 is properly noted as; Secondary air system mass air flow sensor rationality. This fault is indicating that the Mass Air Flow Sensor (MAF) for the air intake of the secondary air injection system is giving a faulty signal. The MAF
The fault is caused when the amount of torque required/requested is mismatched with what can be produced. It is usually caused by an engine issue (programming, wiring, bad MAF sensor, throttle issue, etc). This can be a hard problem to chase down without other codes as well (such as a MAF code, etc. '84 533i sold 5spd. So yeah, just get a can of MAF spray. I use CRC MAF cleaner as well, every time I clean and re-oil the filter. +1000 on don't touch the MAF sensor wire. Also if you have any type of oiled filter, pick up a cleaning/re-oiling "recharge" kit. If at all possible, get one with a spray oil. And SPRAY LIGHTLY.

problem could be one of many start by pluging ur vehiicule to ur DIS it will most definately read bank 1 and bank 2 those are comon codes that apear when ur vehicule isnt run right those r ur o2 sensors second wat comonly is a problem is ur mass air flow sensor wat u can do is unplug it and c how the car rides if it rides fine u know thats ur problembut dont ride without ur mass air flow for
What should the mass air flow reading be on a 330ci when idling? Mine was reading 11.34 kg/h and the tech told me that this was way low and that it should be around 18 kg/h. Any thoughts on this? If this is a low reading, does this mean the MAF is bad and needs replacing? Thanks in advance.
BMW Mass Air Sensor & Air Flow Meters for BMW 7 Series E38 (1995-2001) We sell OEM air mass sensors, air flow meters, and HFMs (Hot Film Meter) for many BMWs. When the mass air sensor is bad you will notice your engine running out of tune. Your fuel mileage will suffer, throttle response will be poor, and you will notice a lack of power.
The original MAF was a Hot-wire type, the new one is a Hot-film thingy. After I replaced it the SES light went on, got the codes pulled and the exhaust cam was faulty, also the O2 sensors had fault codes. Got the cam sensor replaced and the codes erased, after one day the CEL turned on again. This time there were no fault codes at all and the
Replacement: mass air flow sensor – BMW E46 Touring. AUTODOC experts recommend: Сlear the trouble codes from the electronic control unit if necessary. Make sure that no dust or dirt gets into the air duct components and the throttle body. Please note: all work on the car – BMW E46 Touring – should be done with the engine switched off.
