Recently my E320 has been stalling when swtting at red light. After waiting a few minutes it starts and run fine. What could cause it to shut down?
Michael--Sounds like you have the classic fuel line filter problem. Mercedes have a wonderful filter located along the drivers side of the frame. Takes two wrenches to remove; I also use clamping pliers to clamp off the fuel lines on each side of the filter to keep fuel from getting in your face, this also allows the filter to reprime when you release the pliers. Also, make sure your air filter is clean. You can blow the filters out several times befor with compressed air before you have to replace them. Jerry
The crankshaft position sensor in these cars will cause those exact problems, with the joys of no fault codes in any of the systems.Car usually will start after 15 min of sitting. Usually will start to give no starts after a short drive then shutoff(going to the store,running out car will not start)
My 2001 E320 Sedan shuts off while driving. Took it to Autozone to run free diagnostic. Code given PO221, Throttle pedal position TPP sensor/switch "B" circuit range/performance... Explanation Open or short circuit condition... Probable cause Poor electrical connection; Faulty TPP sensor; Faulty throttle value control module. I put Sea Foam in the gas tank and my car has not cut off since/yet. Going to take to mechanic with code information mentioned above to see what's going on. I'm thinking it's dirty sensors, a loose connection or an extremely dirty fuel filter, but we'll see.
