I need help lol




Next, find a full diagnostic system and clear all stored and current codes; After that, drive car for a day or two, then re-scan for current codes. Fix those problems.
A standard OBD-2 code reader only reads the ECU, not the TCU or any other system in a '99 W210. You must use the 38-pin connector under the hood with a Xentry or Star diagnostic system.
Good luck.




Loss of power can be associated with a bad Mass Airflow Sensor ($117 USD) but you will just be throwing money at the car until you connect a diagnostic system! Don't guess!

Your power loss issues I would say are not related to those lights on the dash.
As stated, there are many sensors on these cars that can be a pain. For the past year, I get told to check washer fluid level every time I start the car. I also get P0455 error of a gross leak in fuel system if I fill the tank(no, not topping off) and drive for am hour. Sit idle and low fuel flashes and check engine. I power off, hook up my odb2 scanner, turn to on and erase the code. PIA....but car runs great and I never see or smell a leak. Way too many sensors. I am sure there is a fix but haven't found it yet.
Buy a good code reader, keep it in your car.
