Just want to show you guys a diagram for the turbocharge unite of a C230 kompressor engine. I got this from dealer also with a quote about $1943.00 crazy expensive.

Here's the pictures

C230 Sport Coup

parts.com has it for 1380.
Why are you looking at this? Did yours go bad?
BTW it's a supercharger, but the mb epc calls it a turbo incorrectly.
Check ebay, or send yours out to be rebuilt like here,

It's an Eaton M45 Supercharger, but there are many variations thereof
for different vehicles.
I replaced mine at 120K bought off ebay for $600 and
sold the old one for $250, so only 350 invested,
which is about the price of a rebuild.

Oh my friend has a c230 kompressor coupe, and there's a wired noise everytime car starts, so we went to dealer to ask if that could be caused by low oil in turbocharge. The guy in part deapartment thought we are going to buy a new turbo unite so he pulled a diagram for us, but even him thought this is too expensive.
Later we sent the car to my mechanic for inspection and found no leak from turbo, the noise may be from pully, but so far nothing serious.

As sport coupe said, it's a supercharger not a turbocharger.

MBClub

I used to call it superchager as well, but on dealers print out, it says turbo charge, now i'm confused

Midnight Koop

daaamn... you're a bargain monster! i can't wait to see your hit list for the $100 coupon spree

Jp's_C230k_W203

That's crazy then. If they are calling it a turbo then obviously they don't know what they are talking about. If it was a turbo it would be on the exhaust side instead of the intake side. Oh well. I guess they aren't too smart then lol.

C230 Sport Coup

EPC parts descriptions are often vague or lost in translation.
MBClub, I can almost guarantee you have a pulley and or tentioner
going out.
Mine is making noise these days on start up but goes away after a minute or so when the whatchamacallit valve opens after it's warmed up a bit.
I replaced the pulley and tensioner a while back and it was very quiet,
but it's slowly coming back but only on startups so to heck with it.

If the oil was leaking from the supercharger it would likely be out the front seal. How many miles on the car?
What year?

C230 Sport Coup

ah hah ha
Here's what you need

I Agree with you, i think MB dealers should have upgrade their system, also lower the parts price.

omg this is what I was looking for..............geeez thanks



if calling it supercharger give your ego a boost then call it supercharger............supercharger/turbo......... whatever.........:rolf :

MBClub

my friend's car has aroud 114000, and its a 2002 coupe. well, you know alot about w203, i want to ask you another question about this car. everytime when starting this car, there's a ticking sound from inside of the dashboard and goes away about 1 min, can you give me an advise what kind of problem can this be? I'll suggest my friend to replace the pully and check tensioners. Thank you

Our C230's have superchargers. Superchargers are belt driven, while turbochargers are exhaust driven.

The ticking from inside the dash is part of the climate control system. There are little arms attached to stepper motors to control the various vents/plumbing which break. See the 'sticky' at the top of this forum (Noisy Air Conditioner ?? Stepper Motor Replacement / Clicking & Hissing).

Boosting ego? Nah just wasnt sure if he knew it wasnt called a turbo so he wouldn't look like an idiot in front of other people that's all

C230 Sport Coup

Ha, well I can absolutely guarantee that the wrong pn for a
2002.
Note the 271 that mean it's for the M271 engine, 1.8L
It's still an Eaton M45 but different configuration.
I have the pn for the 2002 around here somewhere if you need it.

114K the SC is probably OK. They are designed to go 100K miles...
and sometimes even double that according to the rep from Eaton I spoke to.
But as I run additional boost.....
Mine was still OK at 120K but I like a reliable car, and don't want to be stuck with my pants down on a long trip without an inexpensive source of parts.
If I waited till it broke, and I either paid someone or paid to tow it,
it would be verrrry expensive like 3 grand vs. doing in advance ~$400 out of pocket.
I had the alternator rebuilt at the same time, and
pulled the SC muffler too, and new belts etc also.
I coulda probably gotten more than 250 for my old one, but it was a forum member who wanted to rebuild it and port it...don't think he ever did.

MBClub

Thanks alot for this information, i finnaly found the problem!

C230 Sport Coup

....and you aren't going to share?
It's always fun to see just how far off the dealers are on their diagnosis.

MBClub

lol... ok I am sharing. Well, after i heard the ticking sound could came from the stepper motor arm, me and my friend decide to take everything apart and find that motor. It took us more then 2 hours to finally reach that part, but we found there's no crack or damage on that arm. To took the motor out actually very hard, because one screw hidden behine the dashboard metal frame pillar. No tool can reach but your hand

Alhough there's no damage we still replaced the plastic arm with our new part, just in cause. Another 2 hours put everthing back together, and test it, the sound still there

But softer... ahhhh, i guess is a gear or something inside the motor is broken, but at least noise is reduced alittle bit.

Maybe after a couple days of good rest we will buy a new motor fix this problem. Tired.....

C230 Sport Coup

R U F'ing Kidding? You tore the whole dash apart because the motor was clicking?
Thats one job I have yet to attempt, mine blows air on your feet no matter the setting,
your feet bake in the winter, freeze in the summer.
There is a DIY with pics here somewhere but wow, I am impressed...
wanna do mine?
Did you run the diagnostic?
Push uh...which is it, recirc and defrost and hold to run
diagnostic on the flaps?

AHAHAHA, the stealer tried to sell you 3 grand of work for a problem in the
air system. Typical.

MBClub

After all that hard work, I'm so exhausted Dealer always try to charge you for a huge amont for any type of job. I used to bought four spark plugs for this 2002 mercedes from dealer cost somewhere around $98, then i went to a local auto zone, their price for four bosh sparks is only $26, I was like: holy ****! That's 4 times more then normal price! only the packaging is nicer with MB logo and stuff.
Aslo my 98 benz has some strange noise from transmission area, I went to dealer, they sent someone go for a test drive with me. After that he won't tell any possibility until i pay for $160 for dignose fee.
But for 3000 for fix a cliking sound or change a tinny motor, its definitely not woth. Do it yourself, slow and detail job only take i will say 2 days.
and if you need help with steps i can tell you, lol... its not hard

hahaitzmickey

Has anyone ever taken off the supercharger? I need instructions on this. Changing out my idler pulley and tension pulley. I want to tackle this project from the top. So I have taken the air box off. Also do you think I need to replace any gaskets while it is off?

Problem: I been having a chirping noise and clicking noise when the air condition is on and i'm reversing or at a dead stop. I took the belt off and resonator. I came across another problem. Everyone please check your power steering pump pulley for a clicking noise next time you change your serpentine belt. It swivels too.. So I believe I will need to replace my power steering pump. Hopefully not, unless they have a pulley replacement for it.

Nictorious

Did you figure out the problem with the steering pump? I seem to be having the exact same problems. I have rplaced the idler and tensioner pulleys and doing the alternator right now. But now i'm worried about the power steering.

Let me know thanks!
