Yes, i have a c230 mercedes kompressor.

not necessarily
when diesels knock and diesel at low rpms it generally indicates a dribbling or leaking injector/s
have an accredited diesel repair shop check it out
If it has some miles on it and the injectors have never been done then the injectors are a fair bet

P0172 p0175 07 c230

Hi, these faults are for a rich self adaption mixture i.e. your exhaust lambda sensors are not detecting enough oxygen. A multitude of things may be causing this fault but I can advise on the most common. - remove the top engine cover and check the round seal at the back to ensure it is correctly fitted - ensure the air filters are not blocked - may be caused by a faulty Air flow/mass sensor - faulty lambda sensor (four fitted to this vehicle) - ensure spark plugs are ok

My C230 Mercedes has check engine light on. Car checked and the following codes were found: P0171 system too lean, P0300 random/multiple cylinder misfire, P0301, 302, 303, 304- meaning cylinders 1 - 4...

P0171 indicates a lean condition. The most common cause of this is a defective mass air flow sensor. Also check if any vacuum leaks.Replace MAf sensor,if cleaning the MAF does not help.

Engine code in my 1999 mercedesE320 is PO173 what

Hi, both codes indicates a bad Mass Air Flow Sensor..
The airmass meter is a common problem. CRC makes an aerosol "Mass Air Flow Sensor Cleaner" that you can try to use to clean sensor.It is located in the intake hose between the air filter housing and the throttle body.

Take care

OBDii code reads 0170 which is a fuel trim malfunction right bank 1998 mercedes c230 where would the MAFsencor be and how do I fix

The MAF Sensor (Mass Air Flow) is located in the air induction system between the air filter and the throttle body.

Be certain to inspect very well for any air or vacuum leaks in the air induction system or for any loose hose clamps or fasteners in the air induction system, especially between the MAF Sensor and the throttle body. There can be no un-metered air entering the engine or the engine performance will be effected and the check engine light, or MIL (Malfunction Indicator Light) will come on, and P0170 is only one DTC (Data Trouble Code) that un-metered air can cause.

Also, be certain to check for any obstuctions on the air velocity grid to the MAF Sensor, or in the air flow to the MAF Sensor such as a plugged up air filter, or something sucked up into the air intake for the air cleaner assembly.

The MAF Sensor can be removed from the MAF housing and cleaned using carburetor cleaner in a spray can to clean off the fine dust that often builds up on the air velocity sensor part of the MAF Sensor and causes poor performance from the MAF Sensor. (it will require a tamper resistant torx bit, and note the position that the MAF Sensor is positioned in the MAF housing so that it is installed back into the MAF housing properly)

Then clean off the MAF Sensor with the carburetor spray. (From a spray can only, and do not submerge the MAF sensor in any type of water, cleaner, or solvent, or the MAF Sensor will be damaged)

If cleaning the MAF Sensor does not solve the problem, then replace the MAF Sensor and be sure to install it with the air velocity grid facing the air filter, and be sure to tighten all the hose clamps or fasteners well.

Here are a few links to MAF Sensors for that vehicle, and an image to help assist you.

What doe the code mean p0171 for 2004 mercedes c230 and my check engin light is on? Can some one HELP me please

either a vaccum leak, or a dirty mass air flow (maf) sensor. the sensor you can clean with crc maf cleaner spray at your local auto parts store. as for the vacuum leak, i heard there is a recall for m271 engines to replace two faulty vaccum lines. one line goes to the s/c, and i believe the other one is right next to it. check if your car needs this recall and go from there.

How do I replace the mass airflow sensor on a 2004 Maxima?

The mass air flow sensor will be in the air intake going to the throttle body. Look for a 3-4" hose, trace that back to a box looking component. The sensor should be in there.

Cleaning the Mass Air Flow Sensor

i will try to help. 171/174 indicates lean condition in engine. the mass air flow sensor is located in the rubber tube going to throttlebody. you can try to clean it. using mild carb cleaner safe for sensors, remove sensor from tube. spray clean the tiny wires located in the cylinder. do not touch them, they are very delicate. these engines are also notorious for leaking intake gaskets and faulty pcv valves. these will all set these 2 codes. feel free with anymore questions.
