Mercedes-Benz C240 Problem Report
Mercedes-Benz C240 Stalling and/or "Crank no Start" Due to Failed Crankshaft Position Sensor
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.
The car wont start, and you have to wait for a while and try again before it starts. When I took it to the dealership, they could not replicate it. It also only happens when the weather is cold - Visitor
Sitting at a light, started to go and car died. Red "Battery/Alternator Visit Workshop" death message appeared. Restarted car and continued on. Took to the shop after work, hooked up to computer for codes, crankshaft sensor hanging on by a thread. Replacement at $249.00. Glad it happened now, driving nearly 1,100 miles next week for OBX vacation! - Visitor
Parked the car in front of our building after driving it briefly (engine was warm). After about a 10 minute stop, tried restarting the car. Engine would crank (turnover) but would not start. Tried three times. Paused for a minute and tried fourth time, and engine finally started with the Check Engine light illuminated. Was not able to take to repair shop until a week after -- we drove the car a few hundred (!!) miles in between without incident. Repair shop scanned computer and told us the Crankshaft Position Sensor was faulty. Replaced the CPSO, part was $100, labor was $115 (one hour), total of $215 plus tax. - Visitor
2003, C240, 1 owner, car stalls, cools down and restarts and runs for about 15 minutes, then stalls. Replaced fuel filter and fuel pump; problem persists! Also, checked battery and alternator (both were o k) after 1'st stall episode. Will look for crankshaft position sensor and replace if possible. - Egranado
Check engine light came on. Took it to the dealership. they said it had mis-fired. and that there was an oil leak that was not such a big deal except that it is leaking onto the Crank sensor!! They reset everything and cleaned everything off, and told me to bring it back WHEN it happens again. Ive only had this car for a month! I wish ihad read this before i bought this car! - Visitor

Engine wouldn't start, mechanic replaced Crankshaft position sensor, then it worked. - Visitor
Car sputtered and stalling in the middle traffic. Unlike other reports, I could not get the car to start again. Had the Crank Position Sensor replaced today; let's see what tomorrow brings with more driving. - Visitor
the car stalled in the middle of an intersection, would no turnover, after several minutes passed and pushing the car out of the intersection the car started. Before we got home the vehicles stalled again when we came to a stop. waited several minutes close to 30 minutes then the vehicle started. The crankshaft position sensor was changes and for now the problem has disappeared. This can be a dangerous problem because the vehicle stalls when ever where ever, it just shuts down without warning. - Visitor
Car engine stopped once 3 days ago. Was able to restart. It got to stop more and more frequently until now it would not crank when cold this morning. Although it did start once, ran for 10 seconds and died. Dash icons are always lit up in key position 2. Battery was 12.5V. Hooked up a battery charger. Had 13.4 V, still would not crank. Changed battery, still no cranking. Swapped fuel and starting relays this did not change anything. In all the testing, the cooling fan activated when the key was in position 2. Also, I have a full tank BUT the low fuel light was also on, in Key position #2. I am thinking of changing the ECM/ECU - stanie
during the winter season, the 1st. start in the morning, the C240 will crank and has a hard time starting. it usually take a few times to start the car. the mechanic thinks the fuel pump might need to be replaced. once the car is started, the car runs like new. i can park the car for hours and it will start up just fine. it is when the car sits overnight that makes the car hard to start. around 37K, i had the C240 completely serviced, all the fluids and filters, spark plugs, Crank Position Sensor and the Cam Sensor. - Visitor
engine cutoff while stopped at light. Took to the dealer, and car would no start until engine cooled off. It's the crankshaft sensor. Cost me $700 to fix. - Visitor
Car would shut-off when it warmed up and would not restart until it cooled down. Changed Sensor and car ran fine when it got warm. - Lethyl G
