Well I came home this past Wednesday and I noticed a spot of liquid on the garage floor. I looked under the car (2005 C230 Sports Sedan w/2100 miles) and saw what looked like blood dripping from underneath. You guessed it. I experienced the transmission leak that seems to be common with the 2005 C-Class. I called my dealership and brought the car in this morning. I brought some printouts from this forum, which discussed the problem, to the dealership in case they were not familiar with the issue. It was not necessary. My service advisor was very familiar with the problem. It took them about ½ an hour to fix the leak and wash the car. In case anyone is interested, here is what was listed on my invoice:

“Found trans electrical plug leaking. Replaced O-rings & modified old plug per P-B-27.00 ”

Does anyone know what “P-B-27.00” refers to? I imagine it is some sort of Mercedes bulletin. I’ll monitor the car to make sure the leak is fixed. I just thought I’d post my experience for others to read.

the same thing happened to my wife's 2004.5 C230K..
Had the car towed to the dealership...the service advicer said he saw most of this case happens on 03 or before C-class and he also said that Mercedes had a new parts for that. However, it still happened to my wife's 2004 and ur 2005...

Leif,

Is yours Automatic Trans or Manual?

Happen to mine about 2 weeks ago.....my dealer had to ordered a new "plug", no mention of the o-rings though, hmmmmm. As of today, it is still "bleeding".

mick1

did you guys take the car in for the 1k mi check up ?

is this something that the dealer could find when they perform the 1k mi inspection ?

thanks.

jan ken po

Yep, I did. It past A'ok. Don't know if my dealer checked for this specific prob or not....the way they seem to be so far, I'm going with "no." I'm at 5300 miles.

Auto or manual?

cntlaw

it happened exactly the same bleeding when I returned home after a trip I did not drive the car for 2 weeks!
So what will happen if I don't get it fixed?

Are you serious?? Just stop and think about what exactly will happen when all your TRANSMISSION fluid leaks out.

@ Baby: Auto

LeifW

To all,

I should've specified that I have an automatic. Also, I had brought my car in for its first complimentary checkup about 300 miles ago. Everything was normal at that time.

Its a known issue on 05 model w203's.

The dealer will replace the faulty o-ring and away you go. (mine's had this done already as well.)

The other small issue w/ 05's is the rattle that comes from the trunk release button if you have music w/ bass. Again the dealer will replace and insulate the switch and problem solved.

Is "P-B 27.00" the service bulletin for this? If so, I will just make sure to inform the dealer at my first service A to do this, thanks.

We should compile a list of Service Bulletins for '05's, anyone know of any others?

mick1

hmmm... if this is a common problem, i wonder why there isn't a recall campaign to address the problem .

My_C55

I dont think they feel its serious enough for a recall, its more of a TSB, so if a car comes in w/ this symptom they know what to do to fix it.

LeifW

My_C55,

I too have the rattle from the trunk release switch. Do you know if they have to take the door panel apart to fix it. I'm concerned that they might introduce some other rattle when they fix the button.

C230 Sport Coup

Anyone know how to check the tranny fluid?
I'd like to check mine...
(Automatic)

i7iceguy

i had a similar problem with my 05 230k.. i took it in for a complimentary fix but a monther following the fix, the transmission fluid started leaking again..

i have to take it in yet again..

Anybody familiar with the lemon rule?

My_C55

I dont know if they have to take the whole door panel off. I dont think so, I'm pretty sure that the window/trunk module pops off

Either way even if they did take off the panel for me it works:
Before = RATTLE... After = Silence!

Just tell them its a common issue and that they need to replace and insulate the switch.

Damn...2 weeks today, and still no call on this "plug". how long does it take to order a damn plug. Somebody is getting an earful tommorrow.
