Well my car was randomly stalling on the streets and was pulling code P0335 which means "Crankshaft Position Sensor Circuit Error". I had problems starting the car after it stalled and I could restart it after a few minutes of cooling down. Apparently the Crankshaft Position Sensor is affected by heat when it fails. I did a lot of research on MBWorld.org and found many threads on the subject: Engine Quiting - MBWorld.org Forums

I pulled it from the service manual already. It just says remove connector but it doesn't say how. There's actually a small clip that attaches to the part. You have to push the rear end down and pull it off. Don't pull on the wire. Then after you have to take a star socket and remove the retaining bolt.

The Mercedes Part # for the Crankshaft Position Sensor is 003 153 27 28. Unfortunately, no local autoparts store in Austin carried it. The average price for an aftermarket part is $80-90. I went to the Mercedes Dealership to get it and the part has been updated to part 003 153 28 28 and it cost $153.90 for the original Mercedes part.

I would say overall that it's easier than replacing a spark plug, but it's in a tight space and you can't really see or maneuver too much. If you're good with mechanics and you have the right tools it should take about 20 minutes to replace, not the 1.25 hours of labor quoted to me.

I've included a bunch of pictures so if you guys ever run into the problem.

Picture #1: Bolt, Star Socket, New part on the left, Old part on the right
Picture #2: Socket, Top of Screw, New on left, Old on right
Picture #3: Rear of engine where sensor is in the center of picture
Picture #4: Picture of where the sensor goes and the bolt hole
Picture #5: Picture of cable
Picture #6: Picture of sensor installed and cable attached
Picture #7: OBD II - no errors

 

Ive read those, but I cant figure out still how to get that damn top part off. that is connected to the wire, tried pulling very hard several times, and nothing. on the passegner side, of the top, where the wire plugs into the sensor, it looks like there is a clip, I tried opening the clip with a knife and pulling, and still nothing. I cant see the retaining bolt without removing this top part. Any adivce?


ugh!Ive tried several times and cannto get that little c*ck sucker off!

 

you have PM....

 

2 hours later and..... nothing... oh ya.... this is why I hate working on cars again, I used to love it. Not anymore though, getting hands cut and burned, too tight, **** dropping, how frustrating . Looks like Im going in to the mechanic. Its shitty too because I know what to do, have the part, fairly easy but the little ******* just wont come off. I tried squeezing and pulling the cap about 100 different ways, its like welded onto the sensor

 

before you give up did you mess around with the clip before you pull it out. it might be seized in place because of heat. that is what damages them in the first place what i would try and be careful is couple light whacks with a rubber hammer or malet of some sort to help loosen it up or see if you can pry it up and wedge a flat head or a wedge in between the metal and the plug.

 

You did find it! To understand how to disconect it and unbolt it look at the camshaft position sensor on the front of the engine to the right of the dipstick. It has the same torx head screw and connector and is much more accessible and easy to see the crank sensor. It is not visible in your picture but on the side towards the exhaust manifold you will find the one torx head srew that holds it in. Take a minute to practice on the cam sensor and it will be much easier to replace the crank sensor.

 

Thank You very much guys, its so frustrating having so much trouble with something so easy. That was a wonderful idea lantana. I didnt know exactly how the two came apart so I was guessing, ill go out first thing tomorrow and check of the camshaft sensor and hopefully thatll gimme a better idea on how to approach it the second time. You too faiz. Thank You!

 

no problem man keep trying and lantana has good advice that should help you out and help you save some money for mods down the road.

remember take a break if you have to get a breather and then get back to wrenching

 

Lame.... still not working. Looking at the camshaft sensor did help tremendously because I now now how the clip actually releases, but not luck. I think the little bast*rd must be like heat welded on or something. Im not superman but im no weakling, I gave it my all as far as tugging power goes and nothing. Guess the mechanic I go. Thank Anyways guys.

 

Rakoom,
If the car will start, you can bring it over and we will get it off. I even have a spare CPS.

PM sent.

Wow Mike, what a nice gesture.....

us XF guys gotta stick together I suppose

 

Way to go!

 

Thanks A Lot Mike! These are the kind of things amongst others, that really help restore faith in mankind.

 

The code said replace crankshaft position sensor which my mechanic did and know the car won't start without help from a battery charge power pack. I replced the battery but something is killing it. It keeps saying replace battery. Did my mechanic forget to hook something back up or what. The car wasn"t doing this until after they work on it.
