![]() When limp mode triggers, your computer might shut off electronic shift solenoids, restricting your engine’s ability to switch gears and locking you into a lower gear that lessens the strain on your engine and transmission – usually second or third. Like the name suggests, your Mercedes-Benz will throttle throttle engine and transmission capacity while in limp mode. It’s pretty hard to ignore when your Mercedes-Benz enters limp mode. Its goal is to get you to your Mercedes-Benz mechanic safely, without further damaging any engine components on the way to the workshop. The purpose of limp mode is to protect you in the event that certain conditions have rendered it unsafe to operate your Mercedes-Benz at its normal level of performance. To avoid such an outcome, your Mercedes-Benz computer will automatically enter limp mode when it receives sensor information that is out of safe operating parameters. This may even result in turbo or engine failure if the overboost condition is sustained. When this information exceeds these safe ranges however, it may result in major problems with your engine or transmission.įor example, your turbo sensors may report that your turbocharger is supplying too much boost pressure, which can stress major engine components like the cylinder head, manifolds and vital engine sealing gaskets. These systems don’t just ensure fuel efficiency and performance, however – they can also double as a safety features, protecting you from electrical and mechanical problems.Īs long as the information coming from these sensors falls within preprogrammed safe ranges specified by Mercedes-Benz, your transmission and engine will continue to function as normal. Too much or too little air can affect your air-to-fuel mix, which can result in reduced performance (in the case of a lean mixture) or poor fuel efficiency and black smoke (in the case of a rich mixture). One example is the mass airflow (MAF sensor), which helps the engine regulate its performance by providing information that helps the computer regulate the intake of air. Today, nearly every system in your Mercedes-Benz is operated by computers, which receive information from a range of different sensors. Today, we will go into detail about how limp mode works, the various problems in your engine or transmission that can trigger it and where you should go for Mercedes service in Melbourne. However, as with anything mechanical, there’s always a slim chance that something may go wrong, triggering limp mode. Combine that with the brand’s reputation for reliability and quality engineering, and the majority of Mercedes-Benz owners never find themselves dealing with limp mode. ![]() Thankfully, regular Mercedes-Benz service helps you avoid the issues that can cause your vehicle to go into limp mode. ![]() When issues are detected, the drivetrain on your Mercedes enters a condition called limp mode to keep you safe, and avoid a serious (and potentially dangerous) mechanical problem. In addition to active safety features like active brake, lane keep and blind spot assist, your Mercedes is also equipped with a computerised system that detects electrical and mechanical problems. ![]() Each Mercedes vehicle comes equipped with a host of different cutting-edge safety features. ![]()
