Find Parts That Fit Your Vehicle

BMW Electrical Sensors, Switches, & Relays

Electrical gremlins can be very frustrating. Luckily your BMW's electrical system is better than most, even if it's 25 years old. Here you will find electrical relays, sensors, switches, and modules for the engine, camshaft, and crankshaft. Our parts are OEM, Genuine BMW, or approved aftermarket brands that we have an excellent track record with. There is no middle ground with electrical parts - it either works perfectly or not. And there's nothing more frustrating than a new part that fails right out of the box. So it's important to choose quality replacement parts over a cheap but faulty piece.

The MOTIV ReFlex+ is an Advanced I/O Integration module allowing a level of precise control of auxiliary components. In addition, the ReFlex can incorporate external data into the factory DME/ECU in parallel through optional CANbus integration. Utilizing the CANbus option, multiple digital and analog signals can be used by the DME/ECU for safety, data logging, or adaptive tuning features. It is unique in its ability to function as a separate standalone, as well as a parallel module in conjunction with the DME/ECU. The ReFlex provides the most accurate and precise supplementary sequential fuel injection with the ability to control other advanced features all in one place. It brings a new level of control, function, and versatility to tuning any modern-day vehicle. Preset crank and cam trigger for most modern-day BMW engines, as well as fully configurable triggers to be synched on any vehicle application. Configurable to operate on 4, 5, 6, and 8-cylinder engines. 3 Point MAP sensor calibration table makes it configurable for almost any MAP or TMAP sensor. Sequential Port Injection with the ability to sense individual injector failures on 4 to 8-cylinder engines. Built-in Ethanol Content Analyzer. The Re|Flex firmware and XDFs include ethanol compensation tables to scale properly for varying ethanol % based on real-time input from the sensor. 2x Additional Outputs. These outputs have 12x12 resolution tables for control in TunerPro R/T. These can be configured to run as on/off, digital, frequency (25hz), or PID. Boost Control WGDC Methanol Solenoid Control PWM (for use with valves such as the Aquamist FAV and the ProMeth Pulse Valve) Nitrous Solenoid Control PWM Auxiliary fuel pump relay trigger 2x Inputs Ethanol Content Sensor Fuel Pressure Sensor (0-10bar) Oil Pressure (0-10bar) Coolant Pressure (0-10bar) EGBP/EMAP (0-10bar) CANbus (not required) enabled communication for the transmission and receiving of digital signals for fully DME/ECU integrated control of external modifications. The CANbus communications also allow for data and errors to be transmitted to and from the vehicle's engine control computer in order to add safeguards and implement engine trips and fail safes. Logging via OBDII is still fully functional and is not affected at all by the communication with the Re|Flex. Some of the developments underway include: Error reporting to and from factory ECU for unparalleled safety Output WGDC by converting an EWG signal to a more conventional DC output for controlling standard 3port and 4port boost solenoids for use with external WG’s The ability to datalog non-factory parameters such as ethanol content, additional pressure sensor, PI IDC, and more! These features make the Re|Flex the most powerful and safest supplementary and auxiliary controller on the market. However, this is only the beginning. As flash platforms find the need for more accessories to control, the Re|Flex was designed to be updated easily by the end user in order to add functionality as it is developed.

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. AAF's Oil Pressure Sensor Relocation Kit allows for an aftermarket low pressure switch as well as oil pressure sensor, or two 1/8' NPT pressure sensors to be installed. This can allow a gauge or light to be on the dash and still log oil pressure in a data logger. This kit also moves the oil pressure sensor away from the engine and onto the chassis (or any other spot) where is it much easier to access, or install larger size diameter sensors. Fits all M20 Engines. Features: 4AN Stainless Steel Braided Line Banjo Bolt and Fitting (installs onto block) 3 Way 1/8' NPT Tee Fitting, for hose from block and 2 sensors. Note: This kit does not come with sensors – the factory low pressure switch can NOT be used. An aftermarket 1/8″ NPT low pressure switch can be used with the factory wire.

This voltage regulator is a crucial component that controls the alternator's output, preventing overcharging by adjusting the current to maintain a safe range of vehicle voltage, thereby protecting the battery and electrical system. Symptoms of failure include dim lights, battery warnings, or a dead battery, often requiring replacement, which can be internal or external to the alternator.

Offered by OEM Schaeffler, this bearing replaces BMW part number 12311739203, which is found in numerous BMW alternators manufactured prior to 1996. This bearing helps to stabilize the shaft of the alternator, allowing it to spin freely. If you are experiencing a loud squeaking or grinding noise from your alternator, there is a good chance one of the internal bearings has failed and needs to be replaced.

This is a replacement Manifold Absolute Pressure sensor Located on the charge air cooler. The MAP controls the amount of fuel that goes through the injectors based on the pressure of air at the intake manifold. If your vehicle is giving you a MAP code, replace it immediately to ensure you get the best gas mileage and performance. It is common for this part to fail slowly and cause poor fuel mileage and hampered performance. When it fails, the vehicle will stutter and stall as it falls into a limp mode. One way to check if your MAP is bad is to unplug the connector before starting your car. If it idles well (compared to a previous poor idle), your MAP sensor likely needs to be replaced. If you let this maintenance part go, your fuel economy will suffer as too much fuel is going into the engine and not being burned. A great way to give your vehicle an efficiency boost.
