Old Elysee's transponder-based electronic anti-theft system is an additional security feature built upon the BOSCH MP5.2 fuel injection system, designed to lock and unlock the engine control unit (ECU) for vehicle anti-theft purposes. When inserting a correct key with transponder and turning to "M" position, the system automatically completes code matching to unlock the ECU, otherwise it cuts off ignition and fuel injection control to prevent engine starting. Extended information: Notes: The ECU compares the received ECM code with its stored ECM code. If codes mismatch, the ECU remains locked and transmits "locked" status to the electronic control box via CE line, triggering warning light flashes and buzzer alarms. Only with matching codes will the ECU unlock to enable engine start.

How to Extract Excess Engine Oil from a Car?

Using a large medical syringe, an IV plastic tube, or a mineral water bottle, wait for the engine to cool down, then open the oil cap to extract the excess. Methods for extracting excess engine oil: 1. Excess oil can be siphoned out. Purchase an 80cm long transparent tube from a hardware store (about the size of a chopstick tip), insert it into the oil dipstick tube, and use your mouth to suck; 2. When the oil reaches about two-thirds of the tube's length, seal the top end and pull out the tube to drain the oil. Repeat this process multiple times to remove the excess oil from the oil pan; 3. Excessive oil can seep into the combustion chamber through the gap between the cylinder and piston, forming carbon deposits. These deposits increase the likelihood of engine knocking and, over time, can cause internal damage to the engine.

Can the Audi Q5 still be driven when the EPC light is on?

Audi Q5 can still be driven when the EPC light is on. The EPC light indicates the vehicle's self-check process. If the light remains on after the engine is turned off, it may be due to a dirty throttle body, which should be cleaned promptly. If the EPC light comes on while driving, the driver can first conduct a basic inspection of the vehicle. If the light appears immediately upon starting the car, this is a normal situation as it indicates Audi's automatic vehicle inspection system and can be temporarily ignored. In terms of exterior design, this vehicle features sharp, angular detailing in elements such as the grille and headlights. The consistent use of straight lines throughout the body enhances the visual width of the car, further elevating its overall sporty demeanor.
