The ABS light in my Mercedes-Benz S350 vehicle is blinking intermittently—it would blink and then go on again. I just replaced my brake rotor and paired it with new brake pads, so I'm sure the problem does not have something to do with them. I am not experiencing any braking problem, but I'm worried it might occur anytime. Any advice on what I can do to make an initial diagnosis?
There are several possible reasons your car's ABS light is blinking, so the pads and rotor are not the only components you should be checking. Have you checked if the brake fluid is still sufficient? This is one possible cause. If the fluid level is already low, the ABS light would usually blink to indicate the condition. You might also want to check for possible leaks in your brake system while you're at it. A damaged wiring harness or a failing wheel speed sensor is another possible culprit behind your problem. Check the entire braking system until you find what's wrong. A blinking ABS light is something you cannot ignore, as the brakes are directly connected to your driving safety.
I'm starting to experience some engine and running problems in my vehicle, and I was told by the mechanic who checked my car that the mass airflow sensor in the vehicle is failing. What is this sensor, and how does it affect my engine's performance?
The mass airflow sensor (MAS) is a sensor that is located between the engine and the air intake. What it does is measure the amount of air that goes into the engine, and then sends the said measurement to the engine computer. The latter handles all the processes happening in the engine during combustion, and everything has to occur at a precise timing. All processes depend on each other, so any problem with just one process would lead to the entire thing failing. For instance, incorrect MAS reading would lead to incorrect fuel amount sent to the engine (to match the amount of air), which would then lead to poor engine performance. Rough idling and stalling are just some of the problems that you might encounter in your drive if you leave a damage MAS unattended.
I have been told that the electronic transmission in my Mercedes-Benz S350 vehicle is susceptible to failure caused by the graphite from the transmission clutch. How true is this? And what can I do to prevent this kind of trouble?
The problem that you mentioned has been mentioned by many drivers of Mercedes Benz vehicles with an electronic transmission that was manufactured in 1996 onwards. The clutch has graphite, and the transmission fluid that circulates in the system often darken over time because of the said element. The problem occurs because the contaminated fluid would often darken the sensor window that is located in the system. This often leads to electronic problems. However, you should not worry too much because the problem can be avoided by simply practicing regular transmission fluid flushing after every 60,000 miles.
