A faulty throttle position sensor can most certainly duplicate all of the symptoms that your Mercedes is experiencing, however a faulty fuel pump or even a defective mass airflow sensor can be the cause to these issues too. I have...
It really depends on if the problems are related or not, they might share the same ground but they get different signals from their respective sensors. It could be as easy as changing the entire dash gauges or it could...
Hi. The anti-lock braking system (ABS) is designed to pump the brake system for the driver in the event of a panic stop. This prevents wheel lock ups and helps maintain vehicle control. The ABS system uses a control module...
Oil and coolant travel through separate passageways in the head and block. Wherever there is a potential cross-over, such as at the cylinder head gasket, or through a crack in the block or head, you can get mixing of the...
Hello, it is unfortunate you are having issues find parts. You may want to try cleaning the throttle itself, cleaning the idle air control valve, and making sure the air filter and housing is clean. Make sure the throttle actuator's...
Hi There, Shaking or vibration (https://www.yourmechanic.com/services/engine-is-shaking-pulsating-or-vibrating-inspection) may be caused by many different things such as faulty spark plugs, poor fuel pressure or misfires. Other things such as a faulty idle air control valve (https://www.yourmechanic.com/services/idle-control-valve-replacement) may cause the engine idle to...
Hi there. Unfortunately, there is no such thing as a "tune-up" anymore. However, there is scheduled maintenance that has a list provided in the owner's manual or on repair sites such as ALLDATA, MITCHELL, etc..... There should be a list...
Hello. It sounds like you have a battery issue. If the jump starting got the vehicle going then that means that the battery alone could not produce enough power to start the vehicle. If the battery is low enough it...
Hello there, ESP will generally not cause the vehicle to die. It sounds like you have a few issues with the lack of power, starting, and the car dying. A few items can cause all three of these. Most common...
The flashing Check Engine Light indicates a fault that has the potential to damage the vehicle's catalytic converter (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-catalytic-converter).

Hello, thank you for writing in. Hoses are generally flexible and can take a decent hit. When you hit a pot hole and send the front of the engine downward, you are more likely to break something that is rigid...
The powertrain control module (PCM) takes inputs from dozens of sensors. It then uses this information to control outputs such as fuel delivery and emissions equipment. If the PCM detects a problem anywhere in the system it will illuminate the...

A crankshaft position sensor (https://www.yourmechanic.com/services/crankshaft-position-sensor-replacement) is an electronic device used to monitor the position or rotational speed of the crankshaft. This information...
Hi there. Unfortunately, we are not able to receive pictures or video to pinpoint damage or identify parts for vehicles through this platform. The best way to identify this item is to search online for a detailed schematic of your...
Your car has an electronically controlled transmission, and I'm willing to bet the problem lies in the control system. Mercedes had some issues with the wiring of the early electronic transmissions, so they were performing a lot of updates when...
Hi there. The dealership would have a replacement key for the vehicle. First try replacing the battery in the key fob or the key it self. Then you will have to reprogram the key to the ignition and the door...
Hello, thank you for writing in. There are several causes for low compression. It was a great idea to test all cylinders. With only having low compression in one cylinder, the issue is likely an exhaust valve. The vehicle should...
Good question. I want to go through a few steps with you and hopefully find your problem and save you some time and money. If you find the issue during steps, then ahead and fix that fault and you should...
Hello there, 8800 is a very high idle. Most vehicles max out at between 6000-7000 RPM. If the vehicle idles at 800 RPM, then this would be considered normal in most cases, unless the idle fluctuates unusually. If the AC...
Hello. Although head gaskets can leak oil, it is not a common cause of oil leaks. More common areas of oil leaks are the oil pan gasket, valve cover gasket, oil filter cap, or the oil filter housing gasket. Before...
