M271 - oil in connectors?

[O'Neille]

This is good information, I got a CPO'd '05 C230K a few weeks ago with just over 50k miles on the odometer. I had a slow day at the office so I decided to wash it while I had my coffee outdoors at 79 degrees F. While wiping down the engine compartment I looked and saw this.



I pulled the cover off and took some close ups to send to my dealership guy.





He showed them to a service guy and I'm picking up a loaner tomorrow while they fix my cam sensors.

I really appreciate the information, Thanks to all who contribute.

I'm also getting that cold air intake hose nailed down where it belongs.

They call a vehicle in that condition a CPO? I'd be PISSED... and probably go to another dealership...

That's just dirt & grime, there's no visible leak. What happens is the leak is in the bushing that seals the wires & connector, so the oil seeps into the harness. The only way to tell is to pull off the connector and see if there's oil inside the connector.

I popped the connectors off before I called the dealer. They were oily but not dripping. I've never seen the problem before so I snapped the pics and mailed them off. The service department made the decision to replace them. I'd rather put 400 miles on their car and not mine anyway.

Update: last week MBUSA issues a service campaign on roughly 60000 vehicles, including the c230 with 271 motor, c230 with 111 motor, and 170 with 111 motor for the camshaft solenoids leaking. This campaign will cover replacement of the camshaft adjustment solenoids, and installation of the adapter harness to prevent leaks from getting into the engine harness. It should also cover any damage that the solenoids may have caused such as oil in the engine harness or damage oxygen sensors. Also you may be able to be reimbursed if you have had to pay for this repair previously out of pocket and your vehicle is now covered by the campaign. So you may want to call your local dealer and see if your vehicle is included in this campaign.

Would you happen to know the campaign number or better yet post the source of this information for those that want to seek additional info?

I'm up in Canada and want to find out if this recall is also offered up north thanks.

I'm interested in this too- will check if they offer it in Germany, but it's highly unlikely.

Hey, That would be great news for all involved, hopefully we can get the service campaign number, will try checking with the dealer next week and see if they know anything

[MBtech2009]

the campaign number is 2009100001, it covers approx. 66113 vehicles. I am assuming these vehicles are all in the usa, but other contries may have a similar service campaign. Your local dealer can tell you if your vehicle is involved if you call the mand give them your vin number. I would also think that most owners should get a letter in the mail.

Mine is covered, just need to wait for them to get enough techs to handle it. Dealership was down to 3 techs from the week of Christmas to the new year.
