BMW Video M54 – Exhaust Camshaft Position Sensor Diagnosing and Replacing – How To Replace E46, E39, E60, E34, X5, X3, Z3
Here’s a video from Bentley Publishing showing how to diagnose and replace the exhaust camshaft sensor on the BMW M54 6-cylinder engine. This applies to many BMWs with the 6-cylinder motor including 3-series 99 thru 05 except M3, 525i 91 thru 96, 525i, 530i 01 thru 03, 525i, 530i/xi sedan and wagon 04,05, X5 2.5 and 3.0 thru 06, X3 2.5 and 3.0 thru 06, Z3 2.5i and 3.0i, Z4 2.5i and 3.0i thru 05.
If you have an engine management fault code (check engine or service engine soon light) for the exhaust camshaft sensor (or bank-1, sensor-2), the first video shows how to diagnose the sensor. If the diagnosis shows a fault sensor the cure is to replace the sensor then reset the fault codes using a reset tool.
The Bentley repair manual (for the applicable chassis) addresses the sensor replacement. Additionally, the video (below) shows the step-by-step process.
