Heavy Duty 95B927804B Front Right ABS Wheel Speed Sensor Fit Macan On the Porsche Macan 95B, a wheel-speed fault doesn't just light the ABS lamp — it also disables PSM, kills traction control, and can make the car feel hesitant on a wet on-ramp. The front-right sensor lives right behind the front hub, soaked in brake dust and road salt; the rear-left sees even more grit. When the Hall element drifts or the D-plug oxidises, you get a signal missing code (FES5 45110 / 45150)
