Regarding the principle of the brake pad induction wire, most people may not know it well. Let me introduce the principle of the brake pad induction wire.
Although the abnormal air flow sensor will not cause the engine to fail to start, it will definitely affect the engine's dynamic performance, such as unstable idling, poor acceleration, "backfire" in the intake pipe and black smoke from the exhaust pipe, and cause exhaust emissions to exceed the standard.
New Mass Air Flow Sensor MAF for Mercedes-Benz is one of the important sensors of EFI engine. It converts the inhaled air flow into an electrical signal and sends it to the electronic control unit (ECU). As one of the basic signals for determining fuel injection, it is a sensor that measures the air flow into the engine.
This paper mainly introduces the maintenance points of air flow sensor
The following is my attempt at a decent pictoral DIY for the crank position sensor (CPS) for 95 and I believe some 96 M3's (and pre 96 nonM M50s).
A check engine light often comes on due to a dirty airflow sensor (MAS). Learn the symptoms of an MAS that needs cleaning, and how to clean it.
