Join us in our Technical Forum Message Board and ask a question to one of our many automotive experts. The BMW 525i has an electric fuel pump. Maybe that's the prob. 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). See our tech article on battery replacing and reconnecting notes. If the collar is damaged during this process, you will need to replace it with a new part. As the fuel level drops, the fuel level sender resistance drops. You can access terminals under the rear seat cushion, below the access panel. Hand tighten the threaded collar. Run the vehicle for about 20 seconds. Anyone know how to prime the fuel pump? Fuel supply, fuel injection: An electrically operated fuel pump, located inside the fuel tank, supplies high-pressure fuel to the engine fuel rail. Fill the fuel tank with about two gallons of fuel before attempting to start the vehicle. The manifolds are equipped with four oxygen sensors, one before each catalyst and one after. BMW E60 cars (2004 - 2010 5 Series) are equipped with digital engine management systems (called Digital Motor Electronics or DME). It is located in the general area of the right rear fuse panel...a little closer to the tail lights...green relay. If the correct voltage is present, but the pump does not activate, it is likely faulty. Information and technical articles within this website are for reference only. Spark timing is not adjustable. Remove it at an angle. VANOS uses engine oil pressure to vary intake and exhaust camshaft timing. Pelican Parts is not responsible for any typographical errors contained within the site. The n54 swap is in motion, along with m5 bumper and skirts, and a bunch of other things being installed! Yea, there are so many variations of things. The M54 intake manifold (red arrow) is also equipped with a 5.5 mm turbulence port for each cylinder. Of course, they won't cover the repair, which is $1000. Reattach the fuel lines and electrical connector to the left side fuel unit. 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. The ECM controls the rotor drive unit mounted at the rear of the intake manifold. 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. 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. The engine is equipped with one or two Valvetronic actuator motor(s), which operate cam gear(s), eccentric shaft(s) and intermediate levers to vary intake valve lift based on ECM signals. The two items below are from newtis relating to my '07 530 E60. Well, just an update...I replaced the fuel pump control module, still no start and the display gave me a fuel pump message. Pelican Parts is not associated with Porsche Cars North America in any manner, except for a mutual appreciation and love of the cars. When it fails completely, you may be left with an engine that doesn't start. Come join the discussion about Bimmerfest events, production numbers, programming, performance, modifications, classifieds, troubleshooting, maintenance, and more! I want to understand which have relays and which have EKPS. Then remove it at an angle. The best way to determine whether the problem is with your relay or your pump is to locate the relay and test it. The E60 uses the module and wife's 2009 X5 still uses a discrete fuel pump relay. In glove compartment. Attach it to the new one. Fuel supply, fuel injection: An electrically operated fuel pump, located inside the fuel tank, supplies high-pressure fuel to the engine fuel rail.Nominal system fuel pressure (engine not running) is as follows, M54 and V-8 engine: approx. It is best to replace your fuel pump with the fuel tank drained. Many were hard to find. The length of the intake runners is varied by turning a rotor. Bringing the BMW community together. Next, you have to remove the lines at the fuel unit. Then remove the four 10mm nuts from the access panel (red arrows). Slide the fuel unit into the fuel tank. Connect the fuel line. Drain your fuel tank. The car is 2009 X5 3.0 N52. 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. Vehicle models change and evolve as they grow older, so the vehicle shown in our illustrations may vary slightly from yours. Exhaust manifolds and oxygen sensors: Oxygen sensor signals are used by the ECM to control fuel delivery. Then press the retaining tabs on the fuel line (green arrow) and slide the fuel line off the fuel unit in the direction of the red arrow. The red arrows point to the Valvetronic motors on the 8-cylinder engine. Do you have questions or want to add to the article? Spark timing is controlled by the ECM using an ignition spark "map". There may go other issues besides engine, if you have car communications errors, it will also disablee the car from starting. Fuel pumps with relays typically run continuously at full speed and need recirc line to fuel tank. If your not pulling any codes, also check fuel pressure at the rail for psi. Multiple sparks per ignition cycle are used to reduce emissions and extend spark plug life. 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. Remove the fuel cap, then slide an anti-static siphon hose down the fuel filler neck.

Hold the carpet out of the way, and then remove the four 10mm nuts from the access panel. Information and technical articles within this website are for reference only. Not sure what else to do. In order to replace the fuel pump, the left side fuel unit has to be removed. Catch any dripping fuel with a cloth as you remove it. When leaving a comment, please leave your vehicle information. 5 bar (73 psi). Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Got more questions? Interestingly enough, wife's 2009 X5 N52 has a discrete fuel pump relay. Leave a comment below. This reduces the amount of possible spilled fuel and fuel vapors. The green arrow points to the bank 2 pre-catalyst sensor. Ok, I get a new one from the dealer (it's green) and he says my old one is behind the glove box. BMW E60 5-Series Technical Articles (2004-2010), Page last updated: Fri 10/23/2020 08:14:32 PM. Now it is time to remove the fuel pump. Pelican Parts is not responsible for any typographical errors contained within the site.
