My wife's 2003 C320 is having the same problems. Sometimes the car keeps on cranking but it won't start and on two occasions the car stalled at the traffic light. We're not sure if it's due to crankshaft position sensor failure but it's very annoying because you dont know what the car will stall. Can anyone tell us the cost to fix the problem? Thank you!

chk eng light came on, hooked up code reader ( adv autopart ), bad crankshaft position sensor.
car will not start if engine hot.
replace crankshaft position sensor about $40. Took 3 hours to find it with on line pictures aid, and 30 minutes to replace
In the morning the car would start fine. After driving about 20 mins. and turing the car off, if will not start up again. I would have to let it cool off anywhere between 5 - 8 hours. Took it to a mechanic, said the fuel injectors were "going" bad, and it would cost $1,400.00 to replace. I declined his service. Since then, the car will stall out at a light, or even while driving. Took it to Advance Auto for free diagnostic. The codes that came up were P0335, P0123, and P0456. I want to fix and keep the car, but I can't afford to spend $1,400 to fix it, and beside, I don't really trust the mechanic's diagnosis.

This happened to me twice today. The second time it had to be towed to the dealer. It puts a sour taste in my mouth being I only purchased this car a month and a half ago. I love the looks and the ride but not the problems nor the price to fix them....

I have had the crankshaft sensor fail twice. The first time the car would stall, and the dash panel would go completely red and say battery terminal problem. After a few minutes if I removed the key and reinserted it, the car would start again and be good for a day or so. The problem showed up in the engine core as bad crankshaft sensor.
About 10000 miles after replacing the sensor, the car gave me trouble starting in the morning and same problem.
Obviously these sensors are not manufactured very well.
