Review on Set of 4 ABS Wheel Speed Sensors Compatible for BMW E39 525 528 540 (Front Rear Left Right) 34526756376 34526756375 by MOSTPLUS by Sebastian Erik

Sensors are ok but the ABS is still not working and "Trifecta" is still displayed. Repaired ABS unit; without change. Checking the sensor diodes showed readings in both directions, indicating NO operation of the diode and thus proving that it is not fulfilling its intended role. They are cheap but I got what I paid for. I had to pay my mechanic twice to replace sensors; That's also money I won't give back. Moral: better buy, cry once.
