I did this yesterday and replaced the sensor but, the connector on my car is different. I mean I could not find a way to plug both ends. I'll take a picture tomorow so you guis can see. Today I also got the check engine light on. The code is P0010 as well. I erased it and will wait to see i it comes back.
I also installed the ASP pulley at the same time. Do yu think that could have anything to do with it?

This is my M111 (C180 2.0L 2002) .... originally from Germany.

As seen in the picture, the CPS connector is filled with oil ... but I don't see oil anywhere else.
Are there specific places to look for traces?

I've checked the fusebox/ECU but don't see any oil. Does this affect the EURO models as well?

It effects all cars. More so on the early M271. Look for signs of oil in your O2 sensor plugs. You might have got lucky in which case fix quickly.

This just happened to me a few days ago!

Engine light came on, the next day it was off:
After 2 days all of a sudden while driving, the engine light warning comes on again.
The engine starts having problems and feels like 2 Cylinders are not working. All of a sudden misfiring and having spasm attack.
It really felt weird. Good Thing I was able to get home. I called Mercedes Roadside Assistance and had my car towed from my home to the closest dealer.
They did a diagnos and found that the Magnet Cam Adjuster leaked internally. And the wiring harness was full of oil.

They cleaned the sensors and wiring harness with solvent and I ordered the " fix"
that Mercedes sells. It is basically a short section of loom with an oil stop in it. Which prevents the oil getting any further loom.

As a preventive measure. Some will say the ECU can be cleaned.
But to Gaurantee no repeat troubles, a new loom and ECU is the mercedes Way!

Glyn M Ruck

Just clean everything & fit the pigtale. If the ECU is dry leave well alone. MB dealers are just parts replacers with little consideration for your wallet.

In this picture the cam sensor does not have the centre plug installed, thus why its leaking oil out the middle.

Unfortunately most parts departments will sell you the cam sensor without the centre plug, since they have to be ordered separately.

Thanks for the suggestion...
I've located the O2 sensors (before and after the CAT) .. but can't seem to find their connectors (by looking in the engine bay).

Are these located somewhere easily accessible so I can do a quick check for oil in them?

fixfox

Anyone please point me in the right direction to locate the o2 sensor connectors please ?
Would really appreciate it.

Glyn M Ruck

I'm not used to working on the M111 - All I can suggest is to follow the wires back from the sensors until you find the connector - It's only about 4 inches from the sensor. Might be easier with the bottom plate off. Or send a PM to C230 sport coup - he knows the M111 backwards.

My aircon has been misbehaving for a while.. coming on by itself when the switch is in the off position. I would then have to manually turn the dial (fan speed) on and back off to shut it down.

This prompted me to check the ECU connectors again. This time I pulled all connectors off it and to my surprise, the middle connector had the first 2 rows of pins with oil.

All other connectors are dry but evidently, it's getting worse with time.

Can anyone recommend an online parts shop that ship internationally please?

fixfox

anyone please?

Hello chaps.

I've recently found this oil leak issue on my C200K '02 model. I understand that has a M111 engine. Its affecting my O2 sensors and I understand there is oil in my ECU as well.

I just wanted to check what the cause of the issue is and if it relates to any of the items below as I'm trying to get this worked covered by my Warranty policy:
Engine {Cylinder head, internal bushings, oil pump, crankshaft and bearings, tappet gear, valves & guides (excluding burnt or pitted valves), pistons & rings, cylinder bores/liners, con rods, distributor drive, starter ring gear, flywheel, autodrive plate, camshaft drive belts, camshaft & cam followers, cylinder head gasket, cylinder block, crankshaft pulley, turbo/intercooler units, rear main seal, rocker assembly, push rods, timing gears, timing belts & chains.}
Fuel system {Mechanical and electrical fuel pumps, airflow meter, injectors (including injector cooling system), overrun cut-off valve, pressure regulator, sensors, throttle
body, fuel gauge and tank sender unit. D.I.S. unit and controls, injection pump, injectors, glow plugs, electromagnetic cut-off.}
Electrics {Internal failure of the starter motor, alternator, alternator voltage regulator, distributor, front windscreen wiper motor and tailgate wiper motor, heating fan motor, cooling fan motor, horn, central locking solenoids and motors, electric window motor and sunroof motor, electric door mirror motors and aerial motors, front and rear windscreen washer motors, headlamp adjuster motors, cruise control unit,
relays, rev counter, radiator cooling fan, indicator flasher unit.}

My friend has a 99 C320 that won't start after sitting for a month. I pulled the cover off the cam sensor and it looked as oil was leaking around it, would this cause the car not to start after sitting.

I also had the Camshaft Solenoid Campaign performed and after 5000 miles / 9 months I'm getting P0010. Right after the solenoid was replaced, the cam advance mechanism started to make a clicking noise. Also it leaked oil and was resealed at the dealership.

Took the car back to the dealership and the are suggesting to replace the camshaft advance mechanism due to an internal failure. Cost $1500. They don't want to acknowledge they broke something during the service campaign. I have no trust in their ability to diagnose of fix problems.

I called MB customer service but they were useless. Any advice?

Glyn M Ruck

What mileage has the car done? What exact noise does it make & when? Does it sound a bit like a timing chain rattle? Does it go away at any time?

The camshaft advance mechanism on a M111 is a pretty robust piece of iron. I very much doubt that it could be damaged by replacement of the cam sensor. They don't even remove the cam box. $1500 is an outrageous price. I'm suspicious of their diagnosis.

I also think they are incompetent crooks. It's the Millennium/Open Road dealership in Bridgewater NJ. They don't even tell me what parts they are going to replace and how much the labor is. I looked on parts.com and the only replaceable part is the Camshaft gear on intake and exhaust ~$800. My car has 125k and it was fine before the open campaign. The sound sounds like a clicking noise similar with a sewing machine. I'll take the car next week to a different dealership.

Did anybody reported a problem to the Better business bureau or Mercedes and got a successful outcome?

Glyn M Ruck

The camshaft adjuster comes as one unit. I had one go sick on me on a non Kompressor W202 in it's first 5000 Km of life. It develops light burrs on the components & rattles/ticks - especially when cold at initial startup. Benz have a method of sanding off the burrs but it was unsuccessful in my case & they ended up replacing it.

totita

I see now, it contains the camshaft gears, actual cams and solenoid. List price is $1535 at parts.com but with the discount is $939. Mine started to make faint noises around 20K but the dealership said it was normal. after 100k it looks like I need a new one. I wonder if MB would cover some of the bill.

Glyn M Ruck

Try pointing out to them that it was reported under warranty.

C230 Sport Coup

Perhaps even Over Retarded?

Hello everybody,

First I have to say sorry about my english skills, hope you guys know what i'm trying to tell

I just bought SLK 230 kopressor manual year -97. It has 161 000 km behind.

We changet timing belts, and the car was working fine. After 2-3 hours resting, I went to start my car. everything was ok, but it has no power. everything else works perfectly, but it feels that the "supercharger" is no on?

so I read finnish mercedes forum, and there were couple similar probles in others cars. I just didn't get answers or anything. So i'm asking you, could problems be leakin cam sensor?

I took a picture about it: http://www.aijaa.com/v.php?i=6882969.jpg

theres no warnig lights or anything else...

thaks for your answers

totita

Anybody knows where the ECU is located on a 2002 C 230 coupe. I just noticed some oil in the connector to the cam adjustment solenoid. Somebody recommended to also check the ECU connector.

Thanks.

Jerkin

just called the dealer.. got an appointment monday to get that sensor replaced due to recall hope they don't mess my car up.....

Hey all who are reading this, I have a 2003 C230k with the m111 and lately it has been dying when warm at idle. its a manual and runs awesome on the highway but when I come to a stop after the car is warm it will die when trying to take off again. I haven't had a chance to check it out under the hood but do these sound like it could be oil in the harness??? also i dont have any codes stored or a CEL.

please any suggestions will be greatly appreciated.

Hey Glyn: Heard today that my Harness is full of oil and the cost will be R30 000 to be fixed up. So far what i have read in the forum is good and well. What cost am i looking at for trying DIY, buying the sensors, pigtails (Whatever that means) Im driving a 2003 C180 compressor (W203) Where would i find a downloadable workshop manual. Im totally stupid in this, but clever enough to realise that MB is ripping me off.
