Check engine light and misfiring
I'm new here and have a major concern with my 2006 c280.
I have only had it for just over a year and have never owned a Mercedes previously. My closest MB dealer is 60 miles away. I just last week had the oil changed for the first time since I owned it. Went to a local dealer that said they could change it and reset the counter. Ok fine...Well they changed the oil and the filter with a MB filter (so they say). Then the Service Manager who said he worked 4 years at a MB dealer told me he couldn't reset the service reminder (he told me he could before they did the service). He said the computer wouldn't let him reset because it wasn't close enough to the due date (had 20 days to go). This concerned me and didn't make sense. Well I took it home and looked online and was able to reset it in about 20 seconds...
Anyways that's a quick history before my problems. Here I go:
The car has been running great since I've owned it. Last Thursday (4-1-10) (crap just realized it was April fools), I had my oil changed. Now Tuesday (4-6-10) my check engine light came on and I've only driven a bit over 100 miles since the oil change. After the light came on it started to become very sluggish and idling very rough. NOT HAPPY!!! I right away thought the place that changed my oil f'd something up. BTW they drained the oil from the oil plug, not from the top.
Ok...So I have a friend who works at another auto shop who at no charge hooked it up to the computer (OBDII). It showed many codes, I lost count at around 12. Something about the O2 sensor and then a sensor not connected or not connected properly (something like that) and also 4 of the 6 cylinders are misfiring!!!!!!!! Not sure what the other codes were. He's kinda baffled at this point but will be putting it up on the jack to see if the other dealer f'd something up underneath.
That is my question...is there something they could have broke or disconnected by changing the oil from the oil plug on this vehicle???
Also I'm PO'd as I only have 36,000 miles on this car and the MB warranty expired 50 days ago. After calling two MB dealerships they said they won't cover me because I'm a 2nd owner...WTF?!?!?
Sorry for the rant and long history but very very frustrated after purchasing what I though was a quality vehicle...
Any thoughts? Thanks!
