2001 c320 with 140,000 miles no crank no start. So far the starter crankshaft position sensor, and battery has been replaced. Owner before me changed the starter crankshaft position sensor and battery. Still no crank no start trouble codes are po123 po128 po133 on the vehicle screen 2 fault codes come up srs restraint system and tele aid.... None of those would cause a no crank no start I never owned a Mercedes and thought how hard could it be let's give it a shot and with a price tag of $500 I'm not giving up on "Hilda" (yes I named my car). Please let me know what pics you need and I'll add them and thank u.
It's out and I'm happy ...... Is bosch standard Mercedes parts or OEM?? I was told starters been changed but I don't know bosch 0001108197 is the part number and one more question out of curiosity...... Is the solenoid removable it looks like it I just like to know because I'm very cheap and if I'm able to just change out the solenoid and not the whole starter I would do it to save money...... For future reference of course...... My girlfriend say I take cheap to the next level......
Just had the starter tested and it's good nothing wrong with it back to square one..... Any ideas anyone has would be greatly appreciated...... Would a push button ignition work?? All fuse have been checked and I replaced the relays with ones I know work...... The starter is getting power and it's grounded properly also

Reason: Update to my dire need
C230 Sport Coup + 2006 W164 ML350 + 99 Ford Escort RIP
Sounds like a starter. CPS would still turn at least.
Starter throws no codes, just stops working.
Just did mine for the 2nd time! Died at a drive through!
No warning. No codes.
Real PIA repair. You'll need like 2 ft of extensions to get the top bolt.
All while laying on your back. No fun. Finding a starter not made in China is not easy either.
And yeah 140K is about it for those starters. Brushes get ground down to nubs and all that carbon gets stuffed inside
the starter. You can clean it, oil it, and put new brushes in and go another 100K miles if you want. Thats what I did...
except I failled to grease it up, but it went another 110K miles on the original and then managed to find a Valeo for like $110.

My girlfriend's best friend had this wonderful automobile and sold it to us for pennies $500 to be exact how hard could it be I can do it...... Then reality kicked me in the nuts I'm questioning my manhood I think my ********* shrunk even....... So I've been told a few ..... Well hell allot of people tried to "fix" this car we were given a duffel bag of parts that were changed out and extra parts..... So far I got an extra fuel pump that was changed out and an ECU I heard the starter and crankshaft position sensor has been changed and I'm willing to bet money no one has done a relearn on anything. So far I tried jump starting with cables no crank no start..... Then I tried using the starter relay with a jump wire pin 3 & 5 still nothing I'm in. The process of dropping the exhaust so I can see the starter and make sure all wiring Is correct. Once that is done I'm going to attempt to install a push button ignition from the starter and see if I can bypass the issue, but if that doesn't work then I know the starter has never been changed and I think to start there I took a couple of pics and the fuel pumps tape job which really scares me plus the access panel is saturated with gasoline. Im not willing to sell this car because I want to experience what all you guys talk about with these vehicles like being in heaven but better.... Lol and is the black box the ECU?? I would snap pic of the car but it's late and the only time I get to work on it is after my second job yes I work from 9am to usually 9pm or as late as 11pm then come home kiss the old lady pop her hood open and eat dinner while I wrench ECU???? On the right and fuel pump on the left what happens is an idiot changes the ECU and does nothing else?? I'm googling the numbers too sorry for the dumb questions lack of sleep and stupid people are wearing off on me.....

only codes are 123 128 133 which I learned are because the battery was disconnect wlthe wrong way

Yeah, no click. Don't bother pulling the exhaust just replace the starter. I wrote a thread on that here like 15 years ago
except different engine. Likely a you tube video out there for M112 engine starter replacment.
Try to find a Valeo or other European brand, not Chinese! You're going to need a scanner that reads MB codes. I'm rather disgusted with my iCarsoft unit, and I'm in the hunt for a better one. You'll get so much more info with one.
If the fact it won't start is the issue, yeah get a scanner. You might have an EIS issue (electronic ignition switch)
but thats a major PIA. It can only be purchased by dealer or authorized mechanic and is coded to the car.
It's like $1000 to replace. But like everyone says, 140K Is pretty much the exact time starters fail on these cars.
No codes, no click nothing. Both times i did it, it was kind of crossing my fingers, is this really the problem?
Yes. it was.
That module looks like a TCU or transmission control unit off hand.
I can't make out the part number. Part numbers are different for different rear end ratios.
It mounts under the kick panel under in the passenger side footwelll (right side) . You wouldn't need one unless oil is wicked from
Trans to the TCU. You can easily pull the carpet back and the panel and check. If it's not, likely one less thing for you to worry about.
That won't prevent the car from starting. You can't replace an ECU. They are coded to the car. It's under the hood with a fat ***
connector. Don't mess with it!!!! If it failed you wouldnt be reading any codes.
You're starting from dirt, but good news is 140K is nothing for these cars, and
3.2 L M112 was a very good engine other than having 12 plugs, 12 wires and 12 coil packs. If they've never been replaced I'd do them
all and a new set of stock iridium plugs. Being on a long trip and running on less than 6 cylinders suck. Or how about only 3? Been there, done that.
And the intake manifolds go bad. Good news is any OBD reader will tell you which cylinder it is, and you can replace it on the fly with hand tools if need be.
I always keep a spare in my trunk. In your case you'll 2 per cylinder.
5 speed trans is good too, but can leak from the electrical connector into the wiring if the o-rings aren't replaced.
And that is a PIA. Other big problem is oil getting into engine wiring harness from cam sensors. Check it
Should be little pigtails on the those to keep it from wicking .
You'll want to flush the trans I wrote a thread on that too. https://mbworld.org/forums/c-class-w...n-related.html
Once you get it running that will be one of the next things youll want to do. Replace all fluids so you have a baseline.
Forget about that used fuel pump. Easy check fuel pressure, I got a guage at Harbor freight for 20 bucks, or
you can borrow one from Auto Zone or Oreily. If access panel under seat is leaking gas get a new seal from the dealer ASAP.
You need a tool like this https://www.summitracing.com/parts/l...00?seid=srese2 but I think I borrowed one
from AutoZone. I ended up have to zip lock the fuel connections with oil resistant zip ties. Came off after pump replacement.
Fuel pump seems to fail at 200K like clock work so doubtful you need it. And it also gives no codes, but it did sort of fade away.
I practically coasted into my work parking lot since gas pedal was dead, but seemed to have just enough fuel to idle. Again no codes, but also no codes for the pedal, and zero fuel pressure so you know. I replaced relay just to be sure and checked fuses too. Nope, fuel pump.
Filter is under the car in the back.
As far as parts go, lot of dealers have websites much less than retail, like wholesale even. Counter prices are outrageous.
Try mercedesbenzstarparts.com but call them 1st to confirm part numbers and availability.
Usually takes about a week. Steven Creek Mercedes in Santa Clara CA.
Here's the service sheet.

Thank you so very much for all the info everything is screaming bad starter and i changed the starter. Still no click no nothing so new battery new starter new crankshaft position sensor what's next ignition switch maybe.i also have "extra " parts from the previous owner which is scary I have two TCM and tons of relays.....

Reason: Uodate
I erased that comment because it was wrong sorry has never been changed the twisted wire isn't twisted wires the ground wire that goes from the solenoid to the starter and it's got to be the starter quick question though is it possible to just change the solenoid even though I know it's tough to get to the starter it's just that this time of the year I'm kind of hurting for cash. I realize it might not be a good idea but Is it feasible
