Click to expand… For the ML class it does not apply to the 2001 models. Also the fault code in the bulletin is for DTC B9103 and DTC B9123. No others would be covered by the DTB. Post # 34 in this thread lists the DTB the parts, and all affected models.

What are all the codes on a Mercedes Benz?

Use an advanced OBD-II code reader to read and erase Engine CEL, Transmission, ETS, ABS, Airbag and other systems. There are also codes for other control units such as transmission, ABS, SRS, ESP, 4ETS, airbag, A/C. Mercedes-Benz can have up to 47 control units. You can NOT diagnose them with a simple OBD-2 scanner.

How many control units does a Mercedes Benz have?

There are also codes for other control units such as transmission, ABS, SRS, ESP, 4ETS, airbag, A/C. Mercedes-Benz can have up to 47 control units. You can NOT diagnose them with a simple OBD-2 scanner. To read these systems and their fault codes or erase them from your Mercedes-Benz you need more advanced OBD-II scanners.

What is the fault code for a Mercedes heater?

P0135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) P0136 O2 Sensor Circuit Malfunction (Bank 1 Sensor 2) P0137 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2)

What are the misfire codes for Mercedes Benz?

Took it to my local Midas and they pulled these codes (P2001, P201F, P2050, P2053) I know the 2 misfire codes are probably from the rough running, but the EGR was recently replaced. Is there something elses I should be looking at here? Firstly please update your profile.

What does the p2001 code on a torque pro mean?

We recommend Torque Pro. The P2001 code usually indicates that the powertrain control module (PCM) has detected a level of nitric oxide (referred to here as NOx), as reported by the post-catalyst NOx sensor, that is higher than desired. Bank 2 refers to the side of the engine not containing the number one cylinder.

What is the Mercedes P2004 check engine code?

Check Engine Mercedes P2004 Code A common failure point for Mercedes-Benz cars equipped with the M272 (350) and M273 (550) engines is the intake manifold air flap lever. When this component fails your Mercedes-Benz will turn on the check engine light triggering any the following codes: P2004 – Intake Manifold Runner Control Stuck Open Bank 1

What to do if your Mercedes P2004 manifold gets stuck?

Place some grease on the ball studs and then press the connecting rod until it locks in the ball studs. Once the vacuum actuator, connecting rod and manifold lever are connected test them by moving the manifold flaps. Ensure that there is no restriction that can cause the manifold flaps to get stuck.

What are the symptoms of a P2000 engine code?

Symptoms of a P2000 code may include: Excessive smoke from the engine exhaust Reduced overall engine performance Possible causes for this engine code include: A defective or overloaded NOx trap or NOx trap element Faulty diesel exhaust fluid injection system Inadequate or improper NOx reductant fluid Inoperable exhaust gas recirculation system

What causes P2000 to be stored in NOx Trap?

Additional diagnostic notes: 1 Incorrect or absent rejuvenation fluid is the most common cause of a code P2000 being stored 2 EGR valve elimination is often the cause of NOx trap inefficiency 3 High performance aftermarket exhaust components can also lead to a stored P2000

What does the P2007 code on Bank 2 mean?

The ECU controls how much to open or close the intake manifold runner flaps and when bank 2 is stuck open the P2007 code is set. This triggers a Check Engine Light to be displayed on the dashboard and a failsafe mode to be enabled. The failsafe mode will remain until the intake manifold runner flap becomes unstuck or the code is cleared.

How can you tell if your engine has a P2007 code?

The most noticeable symptom of P2007 code is the Check Engine Light visible on the dashboard. In some cases the vehicle may have a poor idle, loss of low end engine torque, and an engine that surges. How does a mechanic diagnose the P2007 code? Mechanics will use a scan tool to check for any codes stored in the ECU.

What does code P2017 in OBD-2 mean?

The runner valve controls a flap in the intake manifold, which will open or close depending on the air requirements of the engine. If code P2017 sets, it indicates that the runner valve is not closing and opening as required by the Engine Control Module (ECM); the correlation between the ECM and runner valve is out of sequence.

What does the P2017 code on the intake manifold mean?

What the P2017 code means. The runner position sensor, also known as the runner valve, controls the volume of air entering the intake manifold. The runner valve controls a flap in the intake manifold, which will open or close depending on the air requirements of the engine.

Where is the air flap on a Mercedes p2005?

P2005 – Intake Manifold Runner Control Stuck Open Bank 2 To fix this problem you will need to replace the intake manifold air flap lever using Repair Kit 2721402401. This part is located by the intake manifold.
