My car was diagnosed needing a new crank sensor. How much would a new one cost?

No sir, just diagnosed the problem and how to correct it...........I went to my BMW certified mechanic who servied the car. Charged me $100.00 for a new crank sensor. It was somewhat a pain to get to the crank sensor but he managed to go through the drivers side wheel well ( after removing the wheel ) but he managed to get it done. Now my truck is riding well. All the dash lights are off. The brake light, 4X4 light for taction, and service engine light are all off. Thank you Adrian!
