Engine Light On After Service B
Hey all,
I took my car in for a B service yesterday. The check engine light was not on before I took the car but now it is. It was documented at the bottom of a long list of service detail on the ticket. It says that a quick check shows that it needs an o2 sensor. Now is it strange that after I get it back from the dealer that the engine light is on? I did decline about $1200 worth of service they recommended on top of the $400 i dished out yesterday. When the technician called me to tell me about the recommendations he did not mention the o2 sensor. He only mentioned transmission needed to be replaced, pinion seals were leaking and that I needed rear brakes and rotors and new brake fluid. Should I call back and question them about why the check engine light is now on after I bring the car to them? How can an O2 sensor go bad over night?

$400 bucks was the service B. They charged $75 to run a diagnostic on the transmission. The ticket says the fluid is burnt and clutches are worn. He say that they manager said there was no metal but that it would not get better. He said that adaptation scans came in below MB recommendation. He showed me the codes but he didn't know what they meant either. Question though. I see the charged $210 for the Service B but they charged my for each part needed also. Like 70 for oil and 15 for filter. Shouldnt all of this be included in the Service?

It happened to me once, when I change the air filters. The existing filters were quite dirty and when the new filters were installed there might be a fuel-air ratio sudden change due to new filters. I bought the MAF sensor and replace it to clear CE light. You can just buy a insert only and use back the same housing. The code for MAF is similar to O2 sensor, but the replacement is cheaper & easy.

Do your shifts feel rough? My transmission gives me a rough thump when I shift. I know I need a fluid change, just haven't found the chance yet.
Post the codes if you can.

MAF=Mass Airflow Sensor.
It is very easy to change. First, remove intake air tubings from both front side of the engine. Remove air filter housing ( the big black casing with Mercedes-Benz words across the things) and you will see the sensor very close to firewalls (it is about 4" in diameter). there is a plastic clip holding to the sensor. Unclip the catch and remove it. Then just pull the electrical connection plug attached to it and remove the MAF. In my case, I need to apply a little movement to ease the sensor because it was stuck. Installation is reverse.
You have to wait for a few starts to get the light off.

My dealer wants $335 total. I think its BS, I can get it done myself for under $150, but I'm too lazy to (the process is considerably more involved than changing the oil). I also think its complete BS when Mercedes says the tranny fluid lasts a lifetime.

Don't know what happened but the CE light went off. My wife called me and told me that it went off while she was driving it yesterday. I took it out last night and it stayed off. ???? Well, I am getting the tranny fluid changed tommorrow. I have also noticed that the ride is getting kind of rough. Especially when at 70-80mph. It almost feels like its in the tires because its a constant low vibration. Not like side to side but almost like theres a bump on the tire or something.

First they changed the front tires, no difference.
Then they changed the rear tire, no difference.
Rotated and Rebalanced, no difference.
Inspected the rims, they are fine, still vibrating.
Vibrations are less noticable if the suspension is in Sport II mode, they practically dissapear... I can't figure it out, and Mercedes can't either.
I am planning on getting some 18" AMG rims, but I have a weird feeling that the vibrations will still be there even on the new $4000.00 rims.

Yes, it lowers itself at around 70, 80 mph. Since my car is already lowered, its pimped at 70 mph, but I haven't found anyone willing to take a pic, so I don't know what it looks like.
