At first glance, it may seem strange to talk about potential electronic failures in a BMW car when summer is still prevailing outside the window. Nevertheless, sometimes the summer heat is the main cause of these failures. According to PartEvo specialists, excess air heat is often underestimated by drivers due to its effect on BMW cars. For this reason, they should be taken care of even when the weather conditions seem ideal for the car’s carefree operation.
PartEvo experts emphasise that modern BMW cars have extensive electronics, which only increases the risk of failure during operation. In fact, electronics are found in almost all parts of the car these days, so it is not surprising that failures can occur even in the summer. However, the question remains: which electronic components in BMW cars are most prone to failure during the summer?
Cooling system operation
On days when the temperature outside the window is quite high, the cooling system of all BMW cars, without exception, works much more intensively to maintain the optimal engine temperature. Contrary to what many people think, BMW car cooling systems also contain quite a lot of electronics that help control the engine temperature. A great example is the coolant pump, which in engines such as the N55, N54, N53, N52 and S55 is electric. During the summer, when the car reaches optimal operating temperature faster, these components work more intensively, which also increases the risk of failure. Fans can also be included in the same group of cooling system components that fail in the summer, which are often forced to operate due to high temperatures. Of course, it would also be worth noting that the thermostats in the aforementioned engine models are electric. According to specialists, although these parts are really important, it is not always necessary to choose their original versions. Most well-known manufacturers produce somewhat cheaper, but also high-quality, parts. Before replacing components of your BMW’s cooling system, consider non-original alternatives.
Sensors and other system parts
Various failures, from elementary overheating, can occur in BMW parts such as conventional car sensors, which continuously measure engine parameters and send data to the central engine computer. The computer instantly processes these parts and sends commands to different engine components, enabling them to perform the necessary tasks to optimise engine performance. Sometimes an overheated, damaged sensor can trigger a chain reaction of other problems. In short, poor operation of a single sensor can cause the car to not drive at all or to drive quite poorly. PartEvo specialists say that although it is quite difficult to preventively maintain sensors, drivers who encounter problems with them should not necessarily choose original parts. These days, there are countless well-known manufacturers on the market that produce high-quality, but much cheaper, spare parts, such as car engine sensors. Choosing non-original but high-quality parts will certainly save BMW drivers considerable money and, in many cases, ensure identically high quality and excellent performance.
Therefore, specialists urge you to take care of your BMW cars during the summer – especially before starting long trips during the summer heat. Both the car’s cooling system and various sensors can cause various technical problems, but these days they are quite easy to solve.
