2010 Mercedes-Benz E350

I did a scan for codes with an OBDII Scantool for Mercedes only N code came up a10d00 saying power supply too low(stored) N. The next one read 9a4f13 right KEYLESS GO has a malfunction. THERE IS N OPEN CIRCUIT. CURRENT N STORED HOW DO I FIX IT

Did not find any reference to the second code you mentioned. However, there is a Technical Service Bulletin out related to this code A10D00. It refers a wiring harness being damaged in the area of the roof frame.  This could affect one or all of the following areas:

  • Overhead control panel nonfunctional
  • Bluetooth nonfunctional
  • Multi-function camera nonfunctional or , malfunctions

TSB Reference Number: LI54.18-P-048131, Date of Issue: November 20, 2009 – The entire TSB along with step by step corrective procedures and pictures are included in each manual. – Purchase Manual

Fault Code A10D00

Mercedes-Benz Code A10D00 Description – The power supply is too low.

Control Unit: MFK – Multi-function camera (A40/11)(MPC212)

2004 Mercedes ML500

Radio come on but no sound, I check fuse is there a fiber optic fuse or what could it be?

Radio come on but no sound

I will provide you with the radio wiring diagram to use for diagnostics. If the problem is internal in the radio, replacing it would be the fix.

Front SAM Module Recall Notice

MARCH 2008 — Mercedes-Benz is recalling 3,283 MY 2008 S-Class and CL-Class passenger vehicles. A malfunction may occur on the Signal Acquisition and Actuation Module-Front (SAM-F) transistors. The SAM-F is a double transistor that helps control vehicle functions and the lighting of the center console. Incorrect storage of the transistors led the transistors to be exposed to excess humidity. The presence of this moisture in combination with the thermal stress during the “reflow soldering” may have damaged the transistors while could prevent them from properly functioning increasing the risk of a crash. Dealers will inspect and replace all potentially affected SAMs. The recall is expected to begin during May 2008. Owners may contact Mercedes-Benz at 1-800-367-6372. 08V122

2009 Mercedes Benz R350My vehicle has no power, no crank, no sound, no power. I replaced alternator and battery. Still no power need help please.

RESPONSE

You have a blown fuse or bad connection at the battery. There is an inline fuse called a PREFUSE. This is on the red wire that connects from the battery positive tot he alternator. So you can us a multi-meter and check for battery voltage at the alternator. If you do not see battery voltage there then most likely the PREFUSE is blown. Repair or replace as needed.

2000 Mercedes S430What will be causing my head light and tail lights to go out. They do not come back on after I have replaced the bulbs. Consequently I think that a fuse has blown in my car. please help

RESPONSE

Possible causes would be a blown fuse as you mentioned, a failed headlight switch or lighting module failure. Furthermore some issue may be involved with the wiring harness. Or wiring connection issues but are not as common as the other reasons.

Headlight Switch Operation

The headlight switch operates in 7 positions. The 12 o’clock position is off. The 11 o’clock position will turn on the right side parking lights. The 10 o’clock position will turn on the left side parking lights. The 1 o’clock position will turn on all parking lights, marker lights and instrument panel lights. The 2 o’clock position will turn on the headlights and parking lights. To activate front fog lights, pull headlight knob out to first click. To turn on rear fog light ion addition to front fog lights, pull headlight switch knob out 2 clicks. Fog lights will only turn on if the headlights are in the low beam position, or when all parking lights are on.

Mercedes C180 W203My car has been acting weird recently. It idles roughly (sometimes violently), consumes loads of fuel and at times accelerates sluggishly. The engine light comes on with Code P0102 (air flow circuit too small) and Code P0172 (Mix bank 1 rich).

What should be me course of action to remedy the problems?

Appreciate your assistance!

Jon

RESPONSE

Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
The Code P0102 is set when an excessively low voltage from the sensor is sent to Engine Control Module (ECM).

Mercedes-Benz Code P0102  – Mass or Volume Air Flow Circuit Low Input

The Mass Air Flow (MAF) sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM).

Temperature of the hot film is controlled by the ECM a certain amount. The heat generated by the hot film is reduced as the intake air flows around it. More air, the greater the heat loss. Therefore, the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases. The ECM detects the air flow by means of this current change.

Code P0102 Possible symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • The Engine stalls
  • Engine running rough
  • Excessive fuel consumption
  • Excessive smoke

Code P0102 Possible causes

  • Faulty mass air flow sensor
  • Intake air leaks
  • Dirty mass air flow sensor
  • Dirty mass air filter
  • Mass air flow sensor harness is open or shorted
  • Mass air flow sensor circuit poor electrical connection

Mercedes Benz CodeP0172 – System Too Rich Bank 1

With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. The Engine Control Module (ECM) calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.

In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the ECM judges the condition as the fuel injection system malfunction and light up the MIL (2 trip detection logic).

Code P0172 Possible causes

  • Faulty front heated oxygen sensor
  • Ignition misfiring
  • Faulty fuel injectors
  • Exhaust gas leaks
  • Incorrect fuel pressure
  • Faulty Mass Air Flow (MAF) sensor
