Oil Leak Points — F25/G01

xDrive Leak Detection — Multiple Sources
When an X3 leaves oil spots on the ground, the source can be the engine, gearbox, transfer case, front differential, or rear differential — five possible sources vs two on a rear-wheel-drive car. A fluorescent dye leak test and inspection on a hoist is the only reliable way to identify the source. Do not assume any oil spot is from the engine — let us identify it properly before you spend money on the wrong repair.
