2001 Mercedes-Benz C320 Fuel system Problems

“Malfunctioning seat control modules drain battery in 2001 C320 mercedes benz. Not long after purchasing the car in january 2008 with 51,000+ miles, I paid $175 dollars for a new mbz battery, before asking dealership to disconnect seat control modules. I was not prepared to pay $1200 to replace modules. June 25, 2010, my 2001 C320 stopped during a trip to phoenix, az from california, due to fuel pump going out. My 79 year-old mother and I waited in 100+ degree weather for a tow, which took 3 hours to get to phoenix mbz dealership. …”

“While operating on the highway and in traffic, the vehicle stalls suddenly and without warning because of a 'crank position sensor'. The sensor is a magnet which, when it determines the crankshaft is out of alignment, abruptly shuts down the fuel system. Subsequent models of this manufacturers product do not allow the sensor to do this, but rather indicate a possible problem with a warning light. This sensor system is extremely hazardous and could result in significant injury.”

“Gas fumes so over powering that you had to drive with the windows down after you filled up the car with gasoline. Gas tank had a leak and all the dash was replaced at dealer. However there are shortages in the electrical system that cause the visor lamps to not work and the automatic lights and relays in the wipers do not operate properly. When the heat is on the gas fumes and monoxide is strong again . I thought the problem was rectified when they fixed it but it still tends to act up.”

“Dt: consumer went to start the vehicle and discovered that electrical components such as navigation, radio/cd, telephone, voice command, gas gauges, and power windows were not working. Since then the brake lights and turn signals were replaced twice, and will be replaced the third time in less than a year. Took vehicle to a dealer and contacted mercedes ,who said they could replace navigation and the radio/cd which s\were connected by same computer for $3,000. Dealer did not know why this happened, but there was an electrical short. Have not been replaced or repaired.”

“The contact owns a 2001 mercedes benz C320. The contact attempted to start the vehicle and failed. The dealer removed the fuel pump and found that the plastic component melted. The mechanic stated that he had never seen this type of failure and it could possibly cause an explosion. The mechanic ordered a new fuel pump, and discovered that mercedes was using a new type of wiring connection that linked the fuel pipe to the electrical connection. The current and failure mileages were 76,000. Updated 06/08/07.”
