The video focuses on the common issues and preventive maintenance for the BMW N55 engine, particularly in the 2015 M235i. Fritz outlines six manageable problems, with emphasis on gasket issues, plastic charge pipe, and turbo inlet pipe. He details the inspection and replacement of the valve cover and oil pan gaskets to prevent oil leaks. The charge pipe, prone to breaking under pressure, should be replaced alongside the intercooler and boost pipe for better reliability. Similarly, the fragile turbo inlet pipe should be upgraded with an MST pipe using OEM connections, following a specific installation order for efficiency. Preventative maintenance of these components is crucial to maintaining engine performance and avoiding breakdowns. The speaker also highlights the cost-saving benefits of DIY modifications. Viewers are encouraged to engage with the content and access linked resources for further guidance.

In this part of the video, Fritz discusses the common troubles associated with the BMW N55 engine, specifically in the 2015 M235i. He emphasizes that understanding these issues helps determine if the engine is worth the investment. Fritz mentions the six manageable problems in the N55 engine, starting with gasket issues. He explains how to inspect the valve cover gasket for oil leaks by removing the top engine cover and visually checking the seam for seepage. For the oil pan gasket, he advises inspecting it from underneath the car during a pre-purchase inspection or a visit to the mechanic. If both gaskets are intact with no leaks, there’s no need for further concern.

In this segment, the video discusses the importance of changing out the plastic charge pipe in the N55 engine even if it hasn’t broken yet. The charge pipe, which brings air from the intercooler to the throttle body, is prone to breaking, cracking, or shattering under pressure and heat. The host advises replacing the charge pipe along with the intercooler and boost pipe for preventive maintenance, given their interconnected setup. The detailed explanation continues under the car, where the different parts and connections are outlined. The segment also provides practical tips for ensuring proper installation of the new charge pipe, such as double-checking the seating of the silicone coupler to prevent issues like check engine lights or limp mode. For those on a budget, delaying the boost pipe replacement until handling other issues is suggested.

In this segment of the video, the speaker addresses a common issue with the N55 engine, specifically the turbo inlet pipe, which like the charge pipe, is made of thin plastic and often breaks. The speaker describes the location and installation procedure for the MST turbo inlet pipe, emphasizing that it uses OEM connections for ease of installation. The recommended installation order is to remove the turbo inlet pipe first, then the boost pipe, and finally install the MST turbo inlet pipe to ensure proper clearances and working space. The speaker also advises combining the installation of the turbo inlet pipe and boost pipe due to their proximity, which simplifies the process. Additionally, the speaker discusses the importance of addressing six common issues with the N55 engine in a specific order to prevent problems and maintain performance. They recommend performing preventative maintenance to ensure reliability and prevent the car from breaking down due to minor plastic parts failing. This segment underscores the benefits of doing these modifications yourself to save money and invest in further upgrades.
