It is on the crossover pipe. The part you show in the last picture.

aceracer666

no there is no hole or cabel on the crossover pipe?

If you have 104 Engine, the ITS #: "006 153 20 28", and it should be in the back of the air pipe itself,,

unless if the previous owner change the place of it......!!

how can you have check engine light on your norwegian C36?
there is no display in cluster showing an engine symbol?

I think it depends on the year. I don't have a hole in the crossover pipe either. Check on your mass air flow sensor. I think you'll find it built in there.

If its a 97 like mine the 3.6 crossover may have been replaced as they are really prone to cracking and breaking. But the 3.6 cross over is really hard to find used so a lot of people use cross overs from other m104 engines.

there are no hole in the airpipe or nothing if the last owener change the place it should have been a hole after the original place.

I was outside now and littlebit more look at the car, i tok of the last coil on the end of the engine, and it is all green inside, and when i took it off when the engine was running, nothing happent! so now i also think this coil is broken, aslong this other problem i have not quit the power to the coil?



kowalski: bilen er amerikansk/ the car is from USA

hmm, the MAF sensor broke down for 4 months ago, i change it to a new bocsh (orginal)
But anyway, if this air temp sensor is broken, should i start miss fire ?

Super B

What year is your c36? what is the number on the mass air flow sensor? If you pulled the coil and the engine didn't change then that is your misfire problem. Although the computer should have made a misfire code for those cylinders. (P0304, P0305)

(Your brave for doing that while the car is running. good way to get the **** shocked out of you)

Super B

Do a google search for c36 amg cross over. You'll see that your crossover is not the original. You'll also see that if you have a flat connector mass airflow type of sensor you won't have the intake air sensor like the one you bought nor the hole for it to go in. it looks like that goes to the c36 AMG with the round connector mass air flow sensors.

The coils are cheap. Pick up a set on eBay, a set of wires probably isn't a bad idea also along with plugs. ( the wires are not cheap though ~$200)

As i see from the MAF pic., its "000 094 10 48" or "000 094 18 48", with flat connector,,

in the (W202 C280/C36), the MAF should comes with "000 094 05 48", with round connector,

it could be the complete Engine or Engine Harness been replaced from the late 97-99 "W140 S320"....!!

*not so sure if im right here...?!?

Thanks allot for much good help!
I took off the cooil on the cylinder closest to the driving cabin, nr. 6 (?). And engine did not respond with anything that all! So i ordered 3 new bosch coil and cabels i found on ebay.

The engine code is 104 941 xxxxx . 97 year. I think engine is corect because i changed head gasket and the mercedes center told my they need all engine number to find corect gasket, and they did not say anythinhęg about it was wrong engine.

I can find complete numbers on my maf sensor

cm60k

The Bosch MAF sensor should be: "0280 217 517", is it correct.....??

ZAYED,,

aceracer666

Bosch number on my maf is : 0 280 217 517 and it has flat conetction

cm60k

Sounds good,, that means you have the latest version of the 104 Engine,,

i think you don’t need that IAT sensor, not sure about that,,

C36 owners can confirm that i guess.....!!

ZAYED,,

aceracer666

Yes in the mercedes center they say my engine was produced in the end of the m104 series. So they say it may was some diffrent on my engine than other m104, but they say that they did not know all information a abot what amg made diffrent from the orginial engine

cm60k

That’s strange,, they should have all file/data of all AMG models,,

but i'm not surprised, dealers doesn't want to work hardly...,,

its their STYLE....

ZAYED,,

You and I have the same car since you said it was a North American model. Mine was originally Canadian then one of the previous owners imported it to the states. Only difference between your car and mine is some where along the line somebody swamped out cross over pipe from most likely a c280. As far as the intake air sensor it is built into your mass air flow sensor and hopefully you can return the intake sensor you bought as well as have a warrantee on the mass air flow sensor you have already replaced. Hey can you do me a favor? Next time your under your car can you look at the block ID number and see if it ends with AMG. I looked up the VIN number on mine and all numbers match (engine to car) but my block isn't stamped AMG. I'm wondering if the last years of production I AMG was just trying to get these m104 cars done and skipped that part of the stamping process. From what I've read and seen all previous years of the c36 the blocks were stamped.

aceracer666

cm60k: yes iknow, this guy i spoke to in the mercedes center on the phone here in norway, he told my that it was a litle bit hard to find 100 % corect information about my engine , because he say that amg was not owned by mercedes when this car was made (??) , and it was a littlebit hard to read in the computer, because all the document they had from the amg moddels was just picture from the book's that was just scaned in to the computer... sound strange for me... anyway i have some documents from the mercedes center about this air intake sensor, the sent me in the e-mail today, i will try to put it upp here

super B:

nice, you have a 5 speed og 4 speed gearbox?
Is the intake air temp sensor on the crossover pipe on youre car?

this is littlebit strange, all other c36 engine i found picture off inn internett, have the sensor in the crossover pipe, but mine don't have, then it should be built inn the maf sensor or? is this orginial or what? and why are this maf sensor a problem on this car, also they fast get broken?

you thinking about this long number code on the engine? downside on the exhaust side? i have picture of this number in the phone, because not posibole so fix my head down and read this number without take of much parts and s-hitt... haha.. so my camera saved my as. anyway, i dont found any ''AMG'' letters on the engine block so far..

is there posibole to uppload a PDF file here? if posibole, how please?

Super B

I've got the 5-speed 722.6 and nope no intake air sensor. There is a spot for it on the crossover pipe but the hole is not drilled. I also have the AMG 3.6 crossover. Thanks for looking at that number. It's interesting apparently I you have a 97 don't freak out if the block isn't stamped. Guess they stopped doing that for the last run of cars.

aceracer666

the coil ho fix spark for cylinder 1. and 6. i tok it of the engine when i was running, then engine answer with nothing, but i tok out the sparkplugg and tested, spark comming? but engine not firer all cylinder.. is it posibole that the coil is broken anyway, if it make sparks?

Super B

Hmmm maybe. Do you have your new coils and wires yet? Have you checked the old coil closely for cracks in the plastic housing? This happened to a pair of mine. https://mbworld.org/forums/c36-amg-c...bad-coils.html

aceracer666

No i ordered from ebay, comming 13. May.
This coil ho i think is broken have a smal crack maybe 10 mm long on the side..
I hope ir is the coių andbnot wire harnes...

Super B

Where is the crack at? down the side tower? (The part the resistor boot slides on ) or in another spot?

By 97 they pretty much had the wiring harness sorted out.

aceracer666

yes the crack is on side close to where it is placed on the sparkplugg

i still waiting for all new coil and wires!
