BMW Electrical Sensors, Switches, & Relays for BMW X5 M S63 4.4L

Clear BMW chassis

Please ensure your correct model is selected

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.

If your battery cables have become worn or frayed, or the IBS sensor has gone bad, its time for a replacement. BMW use the IBS, or Intelligent Battery Sensor, to determine not only the state of charge but also the batteries health and life expectancy. Using this data the car's charging system can appropriately supply the battery with the correct voltage, no matter the age.

Comes as a single cable with terminal and IBS Sensor pre-installed.

If you're experiencing hard starting, flaky charging, or other electrical issues, your engine ground strap may be the culprit. On E70/E71 BMWs, the engine ground strap is a thin, non-insulated cable that spans from the left engine mount arm to the frame horn. Despite the seemingly simple nature of this part, on older cars, it is known to cause massive headaches. Due to its non-insulated design, years of exposure to water, dirt, and road salt will cause the wire to corrode, ultimately leading to complete failure. A break in this cable will cause an open circuit, resulting in issues with the vehicle's electrical system and potentially leading to a no-start condition.

To solve this issue, ECS has engineered an exact-fit, upgraded ground strap for your BMW X5/X6! Unlike its OEM counterpart, this design features insulated, large-gauge copper wire for dependable conductivity and long-lasting durability. Additionally, factory-style lugs are zinc-coated, crimped, and soldered, ensuring protection against corrosion and oxidation.

Whether you're replacing a visibly corroded strap or proactively preventing failure, this solution from ECS is sure to provide lasting performance and protection.

FEATURES

Direct-fit replacement and upgrade for E70 X5 and E71 X6 applications Solves intermittent grounding issues caused by aging OEM straps Clean, stealthy design that fits seamlessly in factory engine bays Factory length and lug orientation for drop-in fitment 2 AWG tinned copper cable for excellent conductivity and corrosion resistance Zinc-coated lugs, crimped and soldered to resist moisture and oxidation Black UL1015-grade insulation withstands oil, heat, and abrasion Discreet ECS label for a clean, OEM+ look Replaces OEM part number 12427557027.

The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.

This is a NEW alternator from the OEM manufacturer, Valeo. No core charge applies. Valeo is an OEM manufacturer for many BMW alternators - save money by buying the same alternator in a different box!

This anti-theft throttle controller from Dahler lets you custom-tune your throttle's responsiveness and the security of your vehicle. With 5 preset modes from valet mode to track mode, there are no limits to what you can do. The anti-theft feature completely disables the throttle when activated, so when if in an unfortunate theft situation, even with the car started and in gear, there is no way your car can move, saving your vehicle from falling into someone else's less-than-legal possession. COMFORT MODE (blue) Unfamiliar terrain and too much traffic? This mode lets you take it easy. Your gas pedal reacts less sensitively – especially when starting off. Your stress level will thank you. ECO MODE (green) $5.00 a gallon? There are a few tricks you can use to save fuel and money when driving. This driving program supports you in reducing the average fuel consumption of your BMW if certain rules of economical driving are observed. SPORT MODE (red) This driving program gives your vehicle a much sportier character. Your BMW reacts with a significantly better response and a straighter acceleration. The response time of the engine is significantly improved. TRACK MODE (purple) If you are not yet satisfied with the sports program and you like to push yourself to the limit, then give it a try. For those who go on tracks or run cars with 85 Ethanol this mode might be the right choice.
