View Full Version : Knocking sound under the left side of my '98 BMW 540i (6 speed)

Only about 89,000 miles on the car...had the camshaft position sensor
replaced about 2 months ago yet, I'm just hearing a knocking sound under the left side of the car...this happens only after the car is warm and when I'm switching gears (usually when I'm switching from first to 2nd gear)...can anyone enlighten me on what this "knocking" sound could be?

Those camshaft sensors are useless........

could be a few things, might be your balljoint, but the sound happens usually over bumps. I have a knocking on MY car and it usually happens when i shift gears hard, and its my ENGINE MOUNTS..... i'd check that for starters!
