Hello, i own a bmw i n55, AT, recently i replaced the sparkplugs and one coil. Since then i have the code Pf. When start up the car in the morning the code sometimes is gone, and comes back a couple of hours later. What would be the reason for that? My car has 95k miles. My car has an automatic transmission and M Package No signs of engine malfunction whatsoever, just the annoying "check engine" light.
This code indicates a manifold absolute pressure to throttle valve angle discrepancy. This means that there is some confusion between the mass airflow sensorthe throttle position sensorand the manifold absolute pressure sensor.
It is possible that one of these sensors could be failing. It is also possible that there could be an issue with the throttle body itself.
I would recommend having a check engine light is on inspection performed to determine the exact cause of this issue. Consider YourMechanic as these services can be completed at your home or office.

Beginning in the earlys, BMW revised their naming strategy to get more info out of each character and make it easier to understand updates and revisions.The BMW N55 is a turbocharged straight-six petrol engine that began production in The N55 was BMW 's first straight-six engine to use a twin-scroll turbocharger.
It also won three straight Ward's 10 Best Engines awards in The main differences between the N55 and its N54 predecessor are the use of a single turbocharger, the addition of Valvetronic and the type of fuel injectors.
The N54 uses a twin-turbo arrangement, however the N55 uses a single twin scroll turbocharger. The piezo injectors were more expensive and BMW decided they were not worthwhile outside of Europe, because the potential benefits of lean-burn operation could not be fully realised. The exhaust manifold design, called Cylinder-bank Comprehensive Manifold CCM by BMW, aims to reduce the pressure fluctuations to reduce throttle lag and exhaust back-pressure. As per the N54, the compression ratio is Biturbo engine by Alpina based on the N55B30M0.
The crankcase is of a different design and specially cast by BMW for Alpina. The S55 engine is the high performance version of the N55 engine. Differences compared with the N55 include a closed-deck engine block, lightweight crankshaft, strengthened pistons, different valve material, twin turbos, twin fuel pumps, active exhaust and revised intercoolers. Three water injectors are used to lower the temperature of the air in the intake manifold, allowing the boost pressure to be increased from From Wikipedia, the free encyclopedia.

View My Garage. Hey everyone! I didn't know what code it was throwing but after two weeks of diagnostics, and many new parts with no solution, the CEL went away after they replaced the mass airflow sensor, so I assume it may have been the same code as now.Skynet anet a8 board
Last edited by MuffinMan91; at PM. Remove Advertisements. So last time I posted about this I brought my car to the dealer and they ended up changing the entire throttle body and said this will for sure fix the issue.
Two-ish months later and I'm getting the same code again My warranty expired end of last month but I assume that with bmw two year warranty on repairs, this will still be covered. I hope? Generally yes- Ask to speak with the Dealer GM not the service manager if they balk. BMW generally will authorize a goodwill a repair like this under the circumstances- I've gotten far more than that under CPOnot regular warranty.

One measures a volume of air per unit of time and the other pressure. One is located before the throttle body and the other in the intake manifold. On a NA 6, the MAP sensor is on top of the intake manifold under the cowl tray or whatever it is called that holds the cabin micro filter.
The error description sounds logical. If I open the throttle all the way, I would expect the manifold vacuum pressure to drop which I think means absolute pressure will rise. If it doesn't, then there is a problem of some sort. Note that the error description is the airflow calculated by the throttle angle, not the actual measured airflow. Also note that, at least with the NA engines, there is only one bank of air intake and only one MAP sensor.
MAP sensors are relatively cheap.Wheel and tire specifications with inflation pressures are also available. Explore BMW i …. Explore about 01 Specifications.

X5 35i with K mileage, just got car and have no service history. Very rough idle--Code 28A0 Throttle valve opening angle-intake pipe absolute pressure, comparision pressure too high. Just replaced a filthy air filter-looks like original, cleaned charge pipe an throttle body. I did reconnect vacuum to back of TB with new gasket and electrical connector.
I understand what the computer is trying to compare, just not sure what else to check?? I checked all vacuum lines, pressure switchs, and MAF sensors. Nothing looks out of place.
The Plugs and coil look original, which i will replace. I also found a two pin connector directly below Throttle Body that isn't connected to anything? Pic attached. Attached Thumbnails. Last edited by Jon Beck; at AM. Remove Advertisements. Originally Posted by Jon Beck.

The Camshaft Bearing caps were actually starting to fail!! The sides of the caps were actually expanding on the sides and starting to distort, which would result in complete engine failure in time.

We think that the X5 had a lack of oil changes between K miles, which can cause the oil viscosity to thin out causing the premature wear of each bearing cap. We removed two intake camshaft caps and exaimed them closely to see the wear and expansion on the sides.BMW is no stranger to the turbocharged engine. From their early introduction of turbocharged road cars to current LMP cars, BMW has proven their forced induction engine variants in the hands of commuters and top-performing racing drivers.
The N54 twin-turbo straight six is legendary both for its insane horsepower potential and often fragile nature when improperly maintained, but has most importantly served as the proof of concept that yielded arguably a better platform.
Now sporting a single twin-scroll turbo fed by two exhaust runners, the N55 and S55 engines used in the M3, M4, M2, Mi, and myriad other performance-oriented BMWs has given drivers a more livable modern straight-six turbo. Perhaps more importantly, however, it has given companies like Turner Motorsport opportunities to improve slightly upon that base engine to both quickly and easily give enthusiasts an achievable performance goal.
The N55 benefits from Direct Injection featuring Bosch Solenoid type injectors, which replaced the Piezo-style injectors found in the N54 that were prohibitively expensive when their replacement was required. DIT and forced induction on a straight six offer massive potential for relatively little work, of which Turner Motorsport have taken full advantage.
Noticeable under the hood of our M2 test car, the new Turner Motorsport Carbon Fiber Enclosed Intake is a choice first-step in adding power and marginally improving the underhood appearance for your Npowered BMW. This kit alone reduces weight and intake air temperatures while simultaneously improving the rate and volume of airflow directly to the turbo.
Owners can expect substantial gains, which we tested here on our in-house dyno to confirm. While this may not seem like drastic improvements, the already snappy throttle response characteristic of the N55 is noticeably more responsive and the additional WHP can be felt as the engine reaches peak boost. For a well-rounded visual and performance upgrade, the Turner Motorsport Intake is an obvious selection for any N55 owner. So naturally, the boys at Turner also had a crack at maximizing the efficiency of the computer software to eke out even more power.
Paired with the intake, this software is enough to completely change the driving characteristics of your Npowered BMW thanks to the drastic improvements to power, responsiveness, sound, and acceleration. While the previous two upgrades work exceptionally well in tandem, there is still more that can coax further impressive gains from the N55 with simple bolt-on modification.Bootstrap 4 submenu dropdown hover example
The new Stepped Intercooler from Turner is the tertiary in the coup-de-gras of N55 performance parts. The stepped intercooler drops intake temperatures by 45 degrees F and outlet temperatures by up to degrees with the Turner Motorsport outlet installed, making this an impressive piece of artillery in the fight against performance-robbing heat.
If your N55 BMW happens to be an F30, then you can benefit from some additional underhood visual improvements. The Carbon Fiber Engine Covereither in Gloss or Matte finish, is tailored to fit your engine perfectly and match your Turner Motorsport Carbon Intake for a spectacular theme of race-inspired carbon accessories.
Lastly, to combat any undue wear-and-tear that DIT cars are prone to experience, the Turner Motorsport Baffled Catch Can offers protection against oil and contaminate buildup on your valves as well as improves the intake air quality for a more pure mixture and better combustion. Every available horsepower, reliably accessible, with minimal risks, is what makes the Catch Can our final performance upgrade from Turner for your Npowered BMW. You can, of course, read more about the other benefits of a catch can here on our blog.
With up to more horsepowers, stylish visual improvements to the engine bay, and a preventative measure for carbon buildup in place, your Npowered BMW is well on the way to being a formidable weapon on the street or track. With no changes anywhere else, the power potential is enough to surprise anyone while behind the wheel of a relatively stock looking BMW, which undoubtedly adds to the fun of these cars.
Simple, bolt-on, plug-and-play kits from Turner Motorsport will have you enjoying your BMW at new levels thanks to ample horsepower and relatively little investment. Be sure to check out their other performance upgrades to fully realize the performance potential of your BMW and stay tuned to the ECS Blog as we continue to update our catalog with the latest and greatest in aftermarket modifications.
