The E60 uses the module and wife's 2009 X5 still uses a discrete fuel pump relay. Remove the collar from the fuel tank and store it in a safe place. It will crank and crank but not turn over. The N52 and N52K Valvetronic 6-cylinder engines are equipped with 3-stage variable intake runners in a system known as DISA. See our tech article on Seats removing.
Drain your fuel tank. Instead of a throttle valve, intake air is regulated by adjusting valve lift. Next you have to unscrew the fuel pump module threaded collar (red arrow).
You will need a wiring diagram from a repair manual. Ignition and knock control: The ignition system uses one ignition coil per cylinder, with each coil mounted above a spark plug. However, to prevent engine damage in case of adverse conditions or poor fuel quality, knock (detonation) sensors (green arrows) are mounted on the engine crankcase.
As the fuel level drops, the fuel level sender resistance drops. E60 engines are equipped with two exhaust manifolds, each with an integrated catalytic converter. 1. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. Swap them over to see if it kicks the pump on. Information and technical articles within this website are for reference only. Remove the seat cushion from the vehicle. If your not pulling any codes, also check fuel pressure at the rail for psi. Have a bucket or plastic bin inside the vehicle with you.
3.5 bar (50 psi), N52 and N54 engine: approx. Wrap one end of the wire around the siphon, electrical connecter and fuel line you previously disconnected from the left side fuel unit.
Dinan Engine Software, designed for 2005 - 2011 models, programs the ECM to achieve an upper RPM limit higher than stock.
Use the mechanic's wire to pull it to the right side. You can measure this across the terminals at both sender units with a digital volt / ohm meter (DVOM). Be sure that the O-ring is properly installed in the fuel tank before installing the fuel pump.
See our tech article on fuel pump testing. BMW DME systems comply with second-generation on-board diagnostics (OBD II) standards. The BMW 525i has an electric fuel pump. Researched, and there seems to be no relay for fuel pump.
I don't have fuel or any problems for that matter. It varies the pulse width based on input signals. There are other items to look for a no start.
Fuel Pump Control Unit-Module.Made By BMW. To replace the fuel filter, you have to replace the entire unit. The fuel pump relay is in the front fuse box,there are only two in there. Be sure that the plastic collar is also aligned with the fuel tank (green arrow). Once the lines and electrical connectors are removed, remove the left side fuel unit from the vehicle. Eventually after replacing fuelp pump, ekp, battery, fuel injector seals, I replaced the starter and a faulty crank sensor and that fixed the prob. I want to understand which have relays and which have EKPS. VANOS uses engine oil pressure to vary intake and exhaust camshaft timing.
However, if you do not have this tool you can use a brass punch and a rubber mallet.
Slide the fuel unit into the fuel tank. This equalizes the amount of fuel in the siphon unit. Remove the access panel lid (green arrow) from the body by lifting it up. For the last few days this thing has been driving me crazy.
Thanks for stopping back with the solution. Next, the siphon jet pump has to be removed. Yea, there are so many variations of things. Just to circle back to this...I never got one code. Attach it to the new one. If the collar is damaged during this process, you will need to replace it with a new part. There are two fuel level senders, one in each lobe on the left and right sides underneath the rear seat cushion. Information and technical articles within this website are for reference only. The table below summarizes the DME systems used in E60 cars: Engine control module (ECM): The engine control module (ECM or DME) (red arrow) is mounted in the electronics-box (E-box) at the right rear of the engine compartment. Remove it at an angle.
Remove the mechanic's wire from the old fuel pump. Catch any dripping fuel with a cloth as you remove it. Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. E60 engine management systems--an overview. When leaving a comment, please leave your vehicle information. It will be full of fuel and some will leak. The amount of camshaft timing shift is controlled by the ECM. In the N54 6-cylinder engine, the turbocharger, intercooler and intake manifold (red arrow, just below intake air box) are an integrated system with pressure and temperature sensors and actuators in order to ensure that the volume of intake air is optimal for the engine operating conditions. Using the brash punch and a rubber mallet, tap the threaded collar on one of the ridges counter-clockwise to loosen. Next, you have to unscrew the fuel pump module threaded collar. In turbocharged models (N54 engine), the fuel under system pressure is further pressurized by a mechanically driven pump to pressures as high as 200 bar (2,900 psi) before being routed to the fuel injectors (green arrow). Some weird symptoms for months leading up to a more severe symptom. If something seems different, let us know and share your info to help other users. Once you are sure that the fuel pump is operating normally, fill the remainder of the fuel tank and check for leaks.
Bringing the BMW community together. Controlled fuel pump Functional description, see BMW Technology: ... - Electric Fuel Pump (EKP) control module ... and the E60 M5 info i have refers to it … Do not use incandescent work lights or power tools.
This allows the converters to heat up a very short time after a cold start. Locate fuse box. There are access panels under the rear seat cushion that allow servicing. (There are 2 intake valves per cylinder.) Run the vehicle for about 20 seconds. Never a code. Pelican Parts is not responsible for any typographical errors contained within the site. All pictures and references to the Porsche name, and the car names and shapes are for restoration reference only, and do not imply any association with Porsche. If you suspect your fuel pump has failed, you can confirm the fuel pump has received the correct voltage when commanded ON by the fuel pump relay using a digital volt ohm-meter (DVOM). Align the tab with the fuel tank (red arrow) and press the fuel pump module into the tank. BMW E60 5-Series Technical Articles (2004-2010), Page last updated: Fri 10/23/2020 08:14:32 PM. Then immediately place the fuel pump module in the bucket to minimize spilled fuel. In order to replace the fuel pump, the left side fuel unit has to be removed. Connect the fuel line. 2007 e60 525 n52 3si, nitrous, bms box, 550 comfort seating, center console, rear seating, brakes slotted rotors, m5 sway bars and pull rods. If the correct voltage is present, but the pump does not activate, it is likely faulty. These are microphones tuned to the frequency of engine knock and communicate such knock to the ECM. The fuel pump /sending unit is located in the right (green arrow) side of the fuel tank.
Cover the line with a rag when removing (inset). This will help when routing the new fuel pump. VANOS provides the following benefits: increased power, higher low end and medium speed torque, improved idle and fuel efficiency, elimination of external EGR plumbing (internal EGR) and quicker warm-up and lower emissions. Be careful not to damage the hose or the fuel pump module.
If you are unsure of the amount of fuel in your tank, you can monitor the fuel level via the fuel level sender units. Inputs to the ECM include: air intake volume using mass airflow sensor signal, ambient and coolant temperature signals, accelerator pedal signal, crankshaft and camshaft position signals, knock sensor signals.
Remove the collar from the fuel tank and store it in a safe place. Reattach the fuel lines and electrical connector to the left side fuel unit.
Vehicle models change and evolve as they grow older, so the vehicle shown in our illustrations may vary slightly from yours. Disconnect the negative battery cable.
Consult authorized factory manuals when performing repair procedures. The engine control module (ECM) in these systems is programmed with software for control of fuel injection, ignition and other functions. Bear in mind that BMW's used to have distinct electromechanical relays, and that the control unit may have an embedded relay on the controller, or equivalent electronic switch. Not sure what else to do. Press the retaining tab (red arrows) in toward the line and hold it. Fuel and fuel vapors are highly combustible.
