Common 2018 Bmw M240i problems
The BMW M240i, introduced in 2018, is a high-performance vehicle with a turbocharged 3.0-liter inline-six engine and rear-wheel or all-wheel drive systems. While it offers impressive performance and handling, some owners have reported common problems related to engine issues, electrical systems, and warranty concerns.
Engine Issues
One of the most common problems reported by BMW M240i owners is related to the engine, specifically issues with the N55 engine. This engine is known to develop oil leaks, particularly in the valve cover and its gasket, as it ages.
Another engine-related issue specific to the M240i is overheating. This can be caused by a faulty water pump, which may result in steam coming from under the bonnet and a high-pitched whining noise. The average quote for a water pump replacement is £341.14.
Electrical System Issues
BMW M240i owners have also reported problems with the electrical system, such as faulty indicators. These can be caused by a bad turn signal switch, bulb, flasher relay, or wire. If any of these symptoms are present, it is recommended to have the vehicle checked by a professional.
Warranty Issues
Some M240i owners have experienced warranty issues, particularly related to parts ordered from Germany taking two weeks to arrive and causing extended periods of time out of service. Additionally, some owners have reported that parts could not be replaced under warranty due to fault codes not clearing and resetting properly. In some cases, these issues have been attributed to aftermarket modifications, such as Dinan Stage 1 tunes, causing further delays and complications in the warranty process.
In conclusion, while the BMW M240i offers impressive performance and handling, it is not without its share of common problems. Owners have reported issues related to the engine, electrical system, and warranty concerns. It is important for potential buyers to be aware of these issues and consider the potential costs and time involved in addressing them.
