Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, my name is***** sounds like you may have a bad starter. Check fuse 52 in the driver's side fuse box under the hood and see if it is blown. If the fuse is blown it indicates a short in the starter motor. If the fuse is good you will need to test the voltage to the fuse when the key is turned to the start position. If you are getting 12V to the fuse it indicates an open circuit in the starter motor. If you aren't getting any voltage to the fuse when turning the key to the start position there may be a fault with the starter relay or with the neutral safety switch.

Let me know if you have any questions.
Hi, I'm just checking in with you on the Mercedes. Did you receive my answer yesterday? Do you have any questions?
Hi, yes with a bad starter everything in the car will work except the engine will not turn when you turn the key to the start position. The testing should be performed at the dealer or by an independent Mercedes specialist who has the proper test equipment. The test should be a 1 hour labor charge. A replacement starter is approximately $380 and takes about 2.5 hours to install.
Let me know if you need anything else.
