Fixing Code P0503 - Wheel Speed Sensor

What is the different between BMW and Bosch wheel speed sensors?

I'd prefer to buy aftermarket parts.

Recommendations?

I've found instructions on youtube and the job seems easy enough.

I've replaced all my wheel speed sensors with Bosch ones and haven't had any issues.

Be prepared to replace your axle. Eventually the ABS band around the axle corrodes/swells enough that it throws off the sensor.
