I just got a whopper of a repair bill on my Mercedes C240. The mechanic says I need a new Lateral Accelerometer Pedal and Thrust on Bushings (total cost $1000). This is his diagnosis after an ESP warning came on. Also says I need a new tail light assembly (cost $200). Do these numbers seem reasonable? Advanced thanks for the feedback.

It is a lateral accelation sensor and yes they are pricey. The thrust arm bushings is a common problem in most German vehicles due to the multi link suspension design. Dead give away for bad bushings is bump or knocking noise when you jab the brakes abruptly at slow speeds. As the vehicle thrusts forward the worn bushings cause the arm to contact the sub-frame. Old style taillight housings(and some new ones)melt due to prolonged brake application in stop and go traffic. The metal contacts heat up (bulbs burn at 700-900 degrees F)the heat from the contacts transfers to the lamp assembly causing the plastic to deform. Eventually the metal contact sink into the melted plastic causing loss of contact with bulb holder contacts. If you are handy person you could repair it with epoxy, but it is time consuming and tedious work. I hope I answered all your questions.
