      - Inspect and record tread depth, and correct tire pressure
      - Rotate tires (excludes AMG, Sports Models, SLK, and vehicles with staggered wheels)
      - Engine oil change and oil filter replacement
      -Includes Mobil 1 synthetic oil
      - Lubrication service
      - Includes hood hinges, lock cylinders, striker
      plates, sun roof tracks and top off all fluids
      - Cooling system inspection
      - Includes antifreeze protection level, hoses and
      clamps
      - Brake inspection
      - Includes check of pad thickness and condition of
      discs, fluids and lines
      - Inspect heating and ventilation dust filter, replace if needed. (Replacement additional. Dust filter prices vary by model)
      - Function check
      - Includes warning lamps, headlights, exterior
      lights, seat belts, windshield wiper and washer
      - Inspect and lubricate throttle linkage
      - Check and clean air filter
      - Reset flexible service system counter

      Anything that is not acceptable under Check or Inspect of course costs more to actually repair these items.

      So, basically this is a $300 oil change, plus the checking of everything that you should normally do when changing your oil to make sure that your car is in tip top condition, plus a tire rotation and resetting the FSS light.

      So if you are pretty handy, have some basic tools, and a repair manual you can easily do this job yourself and save.

      P0170 means Fuel Trim Malfunction (Bank 1). P0170 indicates a malfunction in the PCM control of the air-fuel ratio. Bank 1 is the side of an engine that has cylinder 1.

      Possible Causes:

      Dirty or defective MAF sensor
      Vacuum leak
      Defective fuel pressure regulator
      Defective O2 sensor
      Oil contamination in the cam/crank sensor wiring or MAF/O2 sensor connector

      Possible solutions:

      Clean or replace MAF sensor
      Replace fuel regulator
      Replace damaged or cracked vacuum hoses
      Clean cam/crank sensor wiring or MAF/O2 sensor connector
      Replace O2 sensor

      P0422 = Main Catalyst Efficiency Below Threshold (Bank 1)

      Symptoms of a P0422 DTC may include:

      Increased tailpipe emissions
      MIL (Malfunction Indicator Lamp) illumination

      Potential causes of a P0422 code include:

      Bad or non-functional catalyst
      Engine operating out of optimal air:fuel ratio

      Possible Solutions:
      Catalytic converters contain precious metals like platinum, palladium, rhodium among others. Basically, the cheaper the cat, the less precious metals used. It should be noted that there are some automobile makes that are very finicky when it comes to catalytic converters and the logic that the PCM uses to monitor them. Just because the parts guy says it will work doesn't mean that it will. The reason is that the engineering of the vehicle was done with a high quality catalyst in mind and it can't be replaced with a low cost catalyst. There are also different kinds of catalysts. Some makes will allow for a cheaper catalyst while others simply will not.

      heck fuses S and T in the fuse box just to the right of the master cylinder. If the blower motor is not working, try these diagnostic steps I'm listing for you.

      1. With the ignition switch in the on position, use a heavy gauge jumper wire to apply ground to the blower motor wire that is not Red. This wire color varies and is not set by the manufacturer. The Red wire should be B+. When a ground is applied at the wire that is not Red at the blower motor, the blower should run at full speed. If the blower does not run during the test, then the motor is defective.

      2. If the blower motor runs in the previous step, then test for a good ground at the blower regulator Brown wire and a good B+ at the blower regulator Grey/Red wire. The regulator is mounted to the blower motor case in plain sight.

      3. If the previous tests are OK, then using a voltmeter test for voltage at the blower regulator Gray/Green signal wire. This voltage should change as the blower speed is changed at the A/C control. The voltage typically varies around 2 to 6 volts.

      4. If the previous tests all pass, the blower regulator is defective.

      5. If the blower regulator is defective, it is recommended that the blower motor be replaced at the same time.

      Blower motor regulator replacement is recommended anytime a faulty blower motor is replaced, due to the high current stress placed on the blower regulator caused by a failing blower motor.

    What is a service c warning
     
    • Jimm
      6/16/2012 Jimm
      Mercedes service C consists of:

      Change oil
      Oil filter
      Top off all fluids
      Lubricate everything
      AC filter (probably that is the cabin filter)
      Reset system

      Suggest you purchase an inexpensive repair manual and learn to do these basics yourself - to save anywhere from $175.00 on up.
