BMW Electrical Sensors, Switches, & Relays for BMW Z Series E85/6 (2003-2008)

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.

This relay is used for the SMG system on the E46 M3 and various applications including secondary air systems on other BMW's. If you find that your SMG-equipped E46 M3 is not starting, this is one of the first places to check as it controls power to the hydraulic unit (the car will not start without hydraulics). Buy one to fix the issue and buy a second so you're not stranded in the future!

If you're experiencing hard starting, flaky charging, or other electrical issues, your engine ground strap may be the culprit. On older BMWs, the engine ground strap is a thin, non-insulated cable that spans from the 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! 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 E30 (318i/is), E36, E39, E46, and others 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 numbers 12421737755 and 12421714262.

This crankshaft position sensor (CPS) provides the engine computer with engine speed data via the harmonic balancer. It mounts off the engine block and reads the front crank pulley to tell the engine what position the engine internals are in. This sensor is crucial for starting the car as the ECU will not allow the engine to start without this signal.

Located on the intake side of the cylinder head, this sensor relays the position of the camshaft to the computer in order to determine proper ignition timing. When this sensor fails the engine will generally log a fault code and may place the vehicle into "limp" mode. When this happens it is advised to stop driving the vehicle and address the issue immediately as premature wear or long term damage to the engine is possible.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

This seal plug is installed in the valve cover of N52 engines and is supposed to prevent oil from leaking out. But the rubber plug loosens or becomes dislodged over time and oil does seep out of the valve cover and eventually into the sensor itself (destroying a very expensive sensor). In extreme neglect oil will contaminate the engine wiring harness or even the DME itself. During any valve cover work we recommend checking for oil inside the sensor or around this plug and replace the plug during any valve cover gasket work. It's cheap insurance against an expensive contaminated eccentric shaft sensor.

Sensor for: Intake. A common failure - On the S54 engine in the E46 M3, M Roadster, and Z4M, there is one sensor for each cam. The sensor tells the computer the position of the cam on cylinder #1. The computer relies on the sensor's information to set injection timing and VAN0S control. When a sensor goes bad, the computer loses track of what position the cam is in. While the engine will continue to run (taking its measurements from the crank position sensor), the entire system is thrown off. The engine may stumble or run rough, but not misfire, and there will be a loss of performance.

Each cam sensor also doubles as a sensor for the VAN0S. So when the sensor goes bad, the VAN0S will revert to a safe mode and will not advance.

While the engine will still run with a faulty cam position sensor, it's not running in its finest tune. The DME will have fault codes related to the cam sensor or for the VAN0S. This is the Original BMW sensor with a new o-ring.

Applications:
2001-2006 E46 M3, M3 CSL
2006-current E85 Z4 M Roadster, E86 Z4 M Coupe
2001-2002 MZ3 M Roadster, M Coupe (S54 engine only)
