EWS code
I am getting an EWS code, and the car won't start.
Experienced mechanics share their insights in answering this question :
The EWS (Electronic Immobilizer) light on your BMW is an alarm that will cause your car to not start. Something you can attempt is using a different key to start your BMW. If after trying a different key, the car still does not start, it will need to be taken to the dealership so they can reprogram the EWS theft system on your BMW. This is a service only the dealership can provide.

These code systems help keep planning and development organized and avoids confusion. BMW engines are known by their M, N, B, S, P, or W codes while BMW chassis and bodies are known by their E, F, G, or U codes.
If you don`t know your chassis code, you can easily determine it with the last seven digits of the VIN on RealOEM. This will give you basic information, including chassis code, engine, production date, and production code.
Find it in the lower corner of your windshield on the driver`s side. Your VIN number is your vehicle identification number and you can find your engine size by VIN number. In the series of numbers and letters, the tenth from the left denotes the model year and the eighth is the engine codes.
ECU fault codes, also known as diagnostic trouble codes (DTC) are part of the on-board diagnostic (OBD II) system in your car. These codes provide information on which systems are malfunctioning, where the problem is located, and the exact issue that is causing your check engine light to remain illuminated.

Essentially, a chassis code is like a meta description of a vehicle. It designates what chassis a car is built upon, which is often shared across numerous models and makes.
A series production engine will have an eight-digit engine number consisting of two groups of four digits. The 1st block contains 4 digits with information on the assembly line and serial number of engines produced daily. The 2nd block shows the factory code and day of production.
Although there is no specific international or universal standard for engine numbers, they typically range from 11 to 17 digits and often have a code that will be unique to each manufacturer. This enables each manufacturer to identify each individual engine and when it was manufactured.
The P0606 code relates to your engine`s Powertrain Control Module (PCM) and its operability and state of condition. The PCM is the computer that assesses and controls all of your vehicle`s vital components and systems; it is the brain behind your car.
Permanent codes are a special type introduced more recently which can not be cleared using a scan tool. If you have a permanent code the vehicle will clear it itself once the cause has been addressed and sufficient data has been gathered by driving under different conditions (idling, stop and go, highway)

The chassis number is the last six digits of your car`s Vehicle Identification Numbers (VIN), so you need to find the VIN to determine the chassis number. Cars and motorcycles list the VIN in different places, so where you look will depend on the type of vehicle you have.
First Digit: Details of where the car was manufactured. Second and Third Digit: Details of the manufacturer. Fourth to Eighth Digits: Details of the car`s brand, engine type, engine capacity and the fuel type of the car. Ninth Digit: Security code provided by the car manufacturer.
A VIN is composed of 17 characters (digits and capital letters) that act as a unique identifier for the vehicle. A VIN displays the car`s unique features, specifications and manufacturer. The VIN can be used to track recalls, registrations, warranty claims, thefts and insurance coverage.

I have a Code P0601 on the PCM. I replaced the PCM, and now I have a code P0118, code P0123, and code P0193.
ANSWER : Hi there, the short answer to your question is no . A PCM with a P0601 (which is a memory module error in the PCM) cannot reliably retrieve codes for the codes you list (P0118 – coolant temp sensor, P0123 – throttle position sensor, P0193 – fuel rail pressure sensor.
Most likely, the P0601 prevents the PCM from getting any codes from the engine sensors. The memory module error may cause in data corruption for collected sensor values, lose of data over multiple sampling periods, or failure of the data collection to work at all. Replacing the PCM was a necessary expense.
If you need assistance with the "new" codes, I would recommend having a Check Engine Light inspection completed by a mobile, professional mechanic, such as one from YourMechanic, to diagnose the new error codes and get an accurate assessment of the repairs needed.

Can i retrieve CEL code from car … forgot what code it hade in my car .. put headgasket sealer and i erase the code ..
ANSWER : Once a trouble code is erased, it cannot be retrieved. The engine controller does not have a "recycle bin" like they have on Windows. If the car still has a problem, the code will come back up after some driving. However, the controller will not turn on the CEL until it has seen the malfunction on two separate "trips." A "trip" is a driving cycle where the car is started cold, driven until it is fully warm and through a certain number of accelerations, and shut down. So you might not see the CEL for a couple of days. As for the "head gasket sealer," I wouldn’t hold out too much hope of that solving a problem. At the very best it might put off the symptoms for a short while. If you need help interpreting codes that come up, or solving a head gasket issue, contact Your Mechanic. They can send a technician to your home or office to read the codes on your car and help you decide what to do.

It threw a code 21 , throttle position sensor bad code. i replaced it and the code went away but i still have no spark.
ANSWER : Hello and thank you for contacting YourMechanic. The problems that you are encountering with your vehicle, could be caused by the harness to the Throttle Position Sensor (TPS) or the computer itself.
Check the harness to the TPS for any debris or any corrosion. Hook up a paperclip to the harness and turn on the key. Use a multimeter and check for voltage at the pins of the harness. Make sure that the ground on the sensor is grounded and has no resistance. If you find that the harness is having too much resistance, then I recommend having the main engine harness replaced. If you have replaced the harness and still have the same problems, then the computer will need to be flashed or replaced.
I recommend having a professional, like one from YourMechanic, come to your home to diagnose your car’s no start condition before replacing any parts.

Check Engine Light codes. 2006 Mercedes Benz E55 AMG
ANSWER : Since you are getting many different codes from different areas of the engine, you may need to have the system hooked up to a factory scanner since most of these generic codes do not cross over in my repair software. I would also check with the local dealer to see if any service campaigns are open on the vehicle since there are over 30 possible campaigns that could pertain to this vehicle and some of the problems you are having with the secondary air system. This may be the cause of some of the codes and supercharger disabling. If you’d like to have this checked elsewhere, a qualified pro from YourMechanic can come to your car’s location to go through each Check Engine Light code firsthand and have them resolved.

EGR code, Cylinder 4 misfire code 0304 detected.
ANSWER : Hi there. The Exhaust Gas Recirculation (EGR) valve may be not designed for the emissions requirements for U.S. standards. If the EGR is pulling from cylinder number 4 and after replacing the EGR and the computer detects a misfire, then the EGR is malfunctioning and not responding. When you close off the tube to the EGR and the EGR light comes on and the misfire light goes out, then the EGR is not responding to your emissions system. I recommend replacing the EGR with the OEM specified part for the engine and all of the issues should go away. If you need further assistance with your misfire and EGR, then seek out a professional, such as one from Your Mechanic, to help you.

Service engine warning, MAF code and O2 sensor code, along with check suspension light are turned on
ANSWER : Hello, it sounds like you have quite a few things going on. I am going to do my best to break them down for you.
First if the engine is very loud when idling and the belt has already been replaced, there may be an issue with the tensioner or idler pulley.
Next, the Navigator is known for needing service to the air suspension system as it gets up in miles, the most common causes of these are the air struts themselves have failed, or one of the air lines has a leak.
Lastly, if the O2 sensor and MAF are continually coming back after the sensors have been replaced, the most common cause would be either an exhaust leak or a vacuum leak.
Qualified technicians such as the ones at YourMechanic will be able to diagnose these issues and recommend the best path to repair, starting with a diagnosis of your warning lights.

Why do I keep getting a P0101 code in my 2011 Nissan Sentra
ANSWER : Hello. If you are continuing to get the same code then the engine needs to be checked first for any vacuum leaks. The slightest leak in the intake tubes or any of the vacuum hoses or gaskets will cause this. I usually will do a smoke test to find the issue. If there are no leaks then you may have a defective sensor. I do not like to use re-manufactured MAF sensors. If the sensor is known to be good then it may be a circuit issue, which is rare on this vehicle.
