11787569968 Rear Downstream Oxygen Sensor for BMW 528i 528xi 530xi X1 E60 E84

◆ This rear downstream oxygen sensor is a direct replacement for the original BMW unit, designed to measure oxygen concentration in the exhaust after the catalytic converter and provide feedback to the engine control unit.

◆ The OEM reference number is 11787569968 (also written as 11 78 7 569 968). Cross-reference data lists 11787545074 and 11787577666 as related references within the same sensor family.

◆ The sensor is a heated oxygen sensor with a cable length of approximately 480 mm and an M18 x 1.5 thread, engineered to OEM standard dimensions for direct fitment into the downstream exhaust location.

◆ It is primarily designed for the BMW 5 Series E60/E61 with the N52 3.0L engine, specifically the 528i, 528xi, and 530xi models, with aftermarket fitment data covering 2008–2010 for the 528i and 528xi. Broader compatibility data also lists the 1 Series (E81/E82/E87/E88), 3 Series (E90/E91/E92/E93), X1 (E84), and 7 Series (E65/E66).

◆ This product is an oxygen sensor manufactured to meet original quality standards for signal accuracy, fit, and durability.

Q1: Is this a genuine BMW part?

A: The 11787569968 reference is the original equipment part number. Both genuine BMW and aftermarket equivalents (such as NTK/NGK, Meyle, and other OE-quality suppliers) are available that match the original fit and function.

Q2: How do I confirm if it fits my vehicle?

A: Check your vehicle‘s existing oxygen sensor. If it is stamped with 11787569968 or 11 78 7 569 968, this replacement will fit. Also confirm your vehicle is a BMW 528i, 528xi, or 530xi with the N52 engine, or another listed model, and that the position is the rear/downstream sensor.

Q3: What are the symptoms of a failing downstream oxygen sensor?

A: Common signs include a check engine light with oxygen sensor or catalytic converter efficiency fault codes, decreased fuel economy, and failed emissions testing. A diagnostic scan can confirm which sensor circuit is faulty before replacement. Note that downstream sensor codes can also be triggered by a failing catalytic converter itself.
