A female friend was driving a 2007 Mercedes E350. (149K miles) The rubber hose section of the transmission fluid cooler line rubbed against the front pulley. It developed a hole & ruptured while she was driving. It sprayed (pumped) transmission fluid all over the engine compartment & she noticed smoke from under the hood. Then the serpentine belt broke & she lost AC, Power steering, etc. She coasted to the side of the street. The car was towed to me. We replaced the transmission cooler line, the serpentine belt. I have added 9 quarts of transmission fluid (the total capacity is 10.2 quarts). When started & in gear, it will not move (forward or reverse). The transmission dip stick shows full….. I have gone through the process of “resetting” the transmission, with no desired results. What should I do next… check the pump.. or replace the transmission? I hate for her to junk the car as within the last 6 months, she had over $5000.00 worth of work done to the car. These are the 3 trouble codes: P0012 stands for “Intake (A) Camshaft Position Timing – Over-Retarded (Bank 1).” The code indicates that your car's computer has detected a difference in the desired camshaft position angle and the actual camshaft position angle. The P0730 code in a Mercedes indicates that there is an incorrect gear ratio in the automatic transmission. This means that there is a difference between the rotational speed of the input RPM and the transmission output of the RPM. The gear ratio is related to how the torque converter works. A P0015 code in a Mercedes indicates a problem with the camshaft timing that controls the exhaust valves in the engine. It starts up, runs OK… just won’t move… any suggestions?
