As BMW models gradually become equipped with the Gasoline Particulate Filter (GPF) device, some owners are beginning to pay attention to whether this part can be cut to solve the potential problem. When discussing the feasibility of cutting GPFs, we need to clarify a few key points so that car owners can fully understand the possible impact of this move.
Cutting GPF will have an impact on the sale and retention rate of the vehicle. Welding marks can lead to damage to the appearance of the vehicle, which in turn affects the retention rate of the used car market. This is a matter of careful consideration for car owners who are concerned about the long-term value of their vehicles. Cutting the GPF may make the annual inspection of the vehicle difficult, because the main function of the GPF is to reduce the exhaust particulate matter emissions, and cutting may lead to the annual inspection not being completed. This can lead to a range of issues in terms of regulatory compliance and driver's license status.
Cutting the GPF may result in changes in the exhaust system, which in turn can cause resonances in certain speed ranges and produce squeaks and squeaks. This is an aspect that needs to be carefully considered by car owners who are looking for vehicle performance and comfort. The engine may report a fault code and need to be shielded with a computer. If this step is neglected, it may lead to problems such as engine restriction of power output, abnormal idle speed, etc., which in turn will affect the overall reliability of the vehicle.
The act of GPF cutting is considered a breach of the performance of the original vehicle, which may result in the warranty being compromised. Car owners need to be aware that cutting the GPF is an unauthorized alteration of the vehicle, so the manufacturer may deny a warranty claim. This makes it necessary for car owners to maintain their vehicles while balancing the warranty.
Before we think about cutting GPF, we also need to understand why some car owners choose this behavior. The role of GPF is to capture particulate matter in gasoline engine exhaust to reduce environmental pollution. Over time, GPF can accumulate particulate matter, resulting in degraded engine performance, poor acceleration, and soaring fuel consumption. Although the problem is not yet as pronounced in BMW models as it is in Volkswagen models, it may be exacerbated in some regions and driving conditions.
Before car owners consider cutting their GPF, there are ways to help reduce the probability of problems with their GPF. One of them is to use a low-ash engine oil for China VIB, while trying to avoid driving in congested road conditions. This is especially important for car owners who drive frequently in urban areas, where stop-and-go vehicles are more likely to produce PM particulate matter, especially with dual-injection and direct-injection engines at low temperatures and cold starts.
Although GPF has not been used for a long time on BMW models, car owners need to realize that the lifespan of GPF is about 200,000 kilometers under normal use. Due to fuel quality and congested road conditions, this cycle may be brought forward. Therefore, if the owner's BMW is equipped with GPF after the second half of '19, it is advisable to pay close attention to the performance of the vehicle and be prepared in case of possible failures in the future.
Officials have not yet provided a clear solution, and if there is a problem with the GPF, replacing it with a new one may be the only option. The cost is quite high, and it is not possible to claim through insurance. This makes it necessary for car owners to seriously consider the long-term maintenance costs and risks before cutting the GPF.
Cutting BMW's GPF is a multifaceted decision. Car owners need to have a deep understanding of the potential impact, weighing factors such as vehicle performance, regulatory compliance, value retention, and maintenance costs. Before making a decision, it is advisable to consult with a professional technician and manufacturer for more accurate information and advice. Such a holistic consideration will help the owner make a decision that meets the individual needs and condition of the vehicle.
