The secondary air injection pump injects fresh air into the exhaust stream to help burn off harmful pollutants in the catalytic converter. If the injection pump begins to fail, since it is a vital part of the emissions system, a fault code will be triggered. Sometimes, when pulling off the lower secondary air pipe, you may see water pour out. This is a sign that your pump is more than likely faulty. By simply replacing this pump, efficiency can be restored and there will be no worry about failing an emissions test.

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace this and all the other components of the oil separator system to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable.

This is the secondary air pump valve for E9x M3 with the S65 V8 engine. Over time carbon builds up inside the secondary air pump valve causing it not to close properly. This failure to close properly can allow exhaust and moisture to get past the valve and enter the secondary air pump, leading to premature pump failure.

The oxygen sensor is part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The goal of the oxygen sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today.

The oxygen sensor is vital to the performance and drivability of your car. The engine computer relies on data from the sensor to make adjustments in engine efficiency and performance. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance. This oxygen sensor for BMW's with the N52, N54, and N55 3.0L engines. This 490mm bank 2 oxygen sensor is mounted after the catalytic converter.

This exhaust backpressure sensor is a critical component of your vehicle's Diesel Particulate Filter (DPF) system, designed to monitor backpressure levels and trigger the regeneration cycle when needed. By ensuring the DPF operates efficiently, this sensor helps maintain optimal engine performance and prolongs the life of your powertrain.

A malfunctioning sensor is a common cause of check engine lights and DPF-related fault codes. If you're encountering issues with regeneration or fault codes, replacing the faulty sensor is essential to restore proper functionality. Choose this high-quality replacement from Bremmen for a reliable solution to keep your DPF system performing at its best.

The BMW N52 engine was deisgned with a crankcase vent system that relies on a heated oil separator valve to separate vapor from the liquid oil. Under ideal circumstances, the oil vapor would pass back into the intake and get burned up during normal combustion. The liquid oil would follow a path back down into the oil pan and be reused. This system is environmentally friendly but plagued with problems. The heating elements can fail or oil and carbon particles can block the oil separator valve. With no escape, the oil will continue to pool and collect in the valve cover or make its way into the combustion chamber leading to excessive oil consumption, blue smoke from the exhaust, idle and running issues. These issues are worse in colder climates where the freezing temperatures create an oil sludge condition that is impossible to clear. The plastic hoses can become brittle and crack which leads to vacuum leaks and oil leaks. Thankfully, the CCV is replaceable on the early N52 engines (2006 and some 2007 models) and should be inspected during a major service and any time the valve cover is off. Oil can also back up into the throttle body, which is easier to check than the oil separator itself. Later N52 engines do not have a serviceable oil vent as it is integrated into the valve cover and not a separate part.

This is a kit containing the oil separator, the vent hoses, and the intake manifold gaskets that are done during a typical oil separator replacement. Complete kit includes:
  • 11617531423, Genuine BMW oil separator
  • 11617559530, vent hose
  • 11157522931, oil separator hose
  • 11157567801, return hose
  • 11157537701, extraction hose
  • 11617547242, intake manifold gaskets (set of 6)
    The intake manifold must be removed to access the oil separator so new profile gaskets are included. We also recommend (but not required) a new oil separator fitting on the intake manifold because it's one of the heated elements that vaporizes the oil as it enters the intake.

    The oil separator can be replaced on its own but for a complete service we also recommend replacing the oil separator hoses and cleaning the valve cover. Any valve cover or intake manifold work should include a new oil separator valve.

    This kit fits the following BMWs:
    -10/2005 E90 BMW 325xi 330xi - Sedan
    -10/2005 E91 BMW 325xi - Wagon
    -10/2005 E60 BMW 525xi 530xi

    This is the secondary air pump valve for E9x M3 with the S65 V8 engine. Over time carbon builds up inside the secondary air pump valve causing it not to close properly. This failure to close properly can allow exhaust and moisture to get past the valve and enter the secondary air pump, leading to premature pump failure.
