Mercedes W211 M271 Oxygen Sensor After Catalytic Converter Import (BOSCH)

[ GERMAN ENGINEERING ] BOSCH 0258006475 | Diagnostic Lambda Sensor

[ IMPORTANT SOFTWARE DISABLE AND CLEANING WARNING ]

Brake Spray Disaster: When the malfunction light is on, washing a removed old Mercedes W211 M271 Oxygen Sensor After Catalytic Converter part with brake spray, thinner, or rust remover chemicals and reinstalling it instantly poisons the micro-porous ceramic zirconium structure at the tip of the sensor and renders the part completely useless. A damaged sensor cannot be cleaned, it must be replaced.

Disabling the Sensor via Software: Deleting (turning off) the post-catalytic sensor from the engine control unit to get rid of the malfunction light completely blinds the emission control of the W211. The vehicle cannot detect that the catalytic converter is clogged or melted, fuel consumption increases, and it will definitely fail the exhaust inspection.

The legendary elegance of Mercedes is brought to life by the M271 coded Kompressor engines in the E-Class W211 chassis, the sharpest observer of the exhaust line, the quality control expert of the emission system; A-Quality original German engineering BOSCH brand Mercedes W211 M271 Oxygen Sensor After Catalytic Converter is now available! This diagnostic sensor, which monitors how well the toxic gases exiting the exhaust manifold are cleaned in the catalytic converter, sends hundreds of millivolt data directly to the engine control unit (ECU) every second. Over time, due to the use of low-quality fuel, oil burning, or just mileage fatigue, it becomes dull and unable to measure. An old Mercedes W211 M271 Oxygen Sensor After Catalytic Converter with a clogged tip and a broken heating circuit lights up that annoying yellow engine malfunction light on your dashboard, restricts the vehicle's traction (protection mode), and causes you to fail the TÜVTÜRK inspection by disrupting emission values. To eliminate these chronic electronic faults and perfect communication with the engine control unit, you can reset your exhaust measurement system with this brand new Mercedes W211 M271 Oxygen Sensor After Catalytic Converter that meets factory production standards. This imported Mercedes W211 M271 Oxygen Sensor After Catalytic Converter comes in a plug-and-play form with its original socket and heat-resistant teflon wire, restoring your W211's emission values to factory norms.

BOSCH Factory Quality With the signature of BOSCH, a global giant in automotive electronics, it reads the correct diagnostic values sought by the engine control unit in seconds and permanently extinguishes the malfunction light.

Low Fuel Consumption and Traction A brand new Mercedes W211 M271 Oxygen Sensor After Catalytic Converter prevents the engine from disrupting the air-fuel map by accurately reading the catalytic converter efficiency.

Teflon Insulated Ready Socket Thanks to the special cable coating resistant to the thousands of degrees of heat from the exhaust and the plug connector that fits the vehicle perfectly, it eliminates the need for cable cutting and splicing work.

Frequently Asked Questions (FAQ)

The engine malfunction light is on in the vehicle and it shows an "Oxygen Sensor" error. If I buy this Mercedes W211 M271 Oxygen Sensor After Catalytic Converter part, will my problem be solved? The W211 vehicles with M271 engines have 2 oxygen (lambda) sensors in the exhaust line. One is located before the catalytic converter (at the engine outlet / regulated sensor), and the other is after the catalytic converter (diagnostic sensor) as in this advertisement. Your technician needs to read the "Bank 1 Sensor 2" or "Post-Catalytic Oxygen Sensor" error on the computer diagnostic device. If the error is in the first (upper) sensor, this product will not solve your problem; the part locations and cable lengths are different.

Can I cut the product's cable and connect it to my old socket for installation? [ THIS SHOULD DEFINITELY NOT BE DONE ] Oxygen sensor cables are not normal electrical wires; they carry micro-voltage and take reference air through the cable. Cutting and soldering the cable or joining it with electrical tape completely disrupts the resistance values read by the sensor and will cause the malfunction light to come back on as soon as the part is installed. This BOSCH product comes with its original socket and must be installed as "plug-and-play".
