2013 C300 Crank Position Sensor
Where the hell is it? haha. Any info I can find on the interwebz is for older twin throttle body models. There is almost zero room between the motor / firewall. If its hiding back there I quit

If you were to look at the back of the engine block (without transmission in place of course) the crank sensor is installed at the 10 O'clock position.

Bump. Any updates on this? I am stuck too, car dead in the driveway, crank no start. Have new OEM crank position sensor but having extreme problems with removing the old one.

MBWorld Fanatic!
I would get a second opinion are you sure it's the crank position sensor? I asked numerous dealers and Indy shops when I thought my car had an issue they all said they have never changed this part on any 2008+ models.
I bought the pet and spent hours trying to get it from the top end of the engine it seems impossible unless you have baby hands and adult length arms. There has to be a tool for this!
For me it was cleaning the air filters my issues went away. Damn construction!

update: I replaced the crank sensor with a brand new part. It was tricky because the fastener is a T30 torx screw not a bolt as on other models.
BUT
Car still cranks, no start. But seems to pop and stumble at times and seemed to start for 1 second. 55psi at the fuel rail, fuel fuses are good. Torque Pro shows no CEL codes.
Stuck with no car for 4 days, any other tips?

Maybe someone could guide me to which relays or fuses to check on ignition spark side?

Here are some tips as most of the instructions on youtube and elsewhere are misleading or incorrect:
On my w204 there are the following major differences:=left
1. less room than with other models as valvecover/vacuum pump attachment extend far over the top of the sensor towards the firewall. Either you try by feel alone, or remove the vacuum pump to give you a couple more inches of room for your hands.
2. The sensor is attached via a torx screw (T30 confirmed) rather than a torx bolt. Confirm yours first with a boroscope or camera as misleading instructions wasted an hour of time
3. The connector on top of the sensor is a 90 degree right angle with white sliding clip, similar to the tricky new connector to the MAF. The 90 degree appears to be on this model due to the limited clearance per #1 above and another sensor close above it. Most examples on the internet do not have the
90 degree connector.
(The sensor connector is on the right-hand side of the photo above)
Only use a genuine part. Note the part I purchased was updated a few times so I am hoping this one is engineered to last longer.

Does your engine have a single or dual air intake? I've seen it located pretty easily on the dual intake models from youtube videos etc, but I can't find much help with the 2013 single air intake models. (i'm referencing the intake because that's the most obvious difference looking at the motor) On my car there is a shield on the back of the motor that was near impossible to remove to access that area.
