Check engine light came on, dealer wants 6000 and they're not saying if that will even fix it. They say it's the coil packs, O2 sensors ( left and right) and/or spark plugs. I just had B serviced done 2 weeks ago.

Figuring out what I'm going to do, not fixed.
cost me over 500 just to have it diagnosed.
Replaced both coil packs @ $1400.00 each ($2800.00) 24 NGK Iridium Spark Plugs @$20.00 each x 24 ($480.00) Plus labor & sales tax.. Then replaced both catalytic converters with OEM Mercedes and O2 Sensors $2600.00+ Labor. & tax and car runs worst then anything I ever owned and no one can figure this shit out!!! WTF!! Is the problem!! Drove the car only 5,000 miles since I bought it in August 2013 .. Oh almost forgot $3000.00 for New front Airmatic struts for the front!! Unbelievable!!!
