Hi guys, yesterday i was just taking a look under the hood and just for curiosity i disconnected the ecu and find out that one of the conectors is sticky and oily, the other one looks brand new though.
the car runs well ( by the way ). what can cause this issue as there is no oil hose or line near the conector or the ecu? what do you recommend to clean it? will the car improve its performance if i clean it?
here is a video of the issue

Do you have any history on your w202?

Hello my friend, i am sorry but i don't know how to add my user cp info to my profile, can you help me with that please?
this is my first mercedes, i love the way it looks because it has the c36-c43 amg looks, with the mono progressive rims and the ground effects.
all i know is that i am te 3rd owner, and that the second one did a major restoration on the car. it drives very good with no suspension noises and it is very tight, interior is an 8, exterior 8 as well, it is a manual transmission and, i will not lie, i would like to have a little more power. i know i can't ask too much out off an 2.2, but being a manual i can use an extra 20 hp. My benz is my personal car and it is a daily driver. my goal is to fix the little things that i don't like, like the ac - heater issue and the rams going down almost to the point of stall when i get to a stop or a red light.
basicaly thats it, i will really appreciate all the info you can give me. my car was sold for the mexican market, i know thanks to you, that my car doesn't have an ege valve nor a pcv - oil separator valve.

 

 

Done!
