BWM vehicles, like most cars, have computer and sensor systems that produce error codes to help diagnose component or system issues. Your BMW dealership can run these engine diagnostics to identify and repair issues, even if you haven’t noticed their effects. This maintenance can keep your BMW running smoothly. However, properly using computerized diagnostics requires more than simply reading a diagnostic code.
Why a BMW Dealership Performs the Best Engine Diagnostics
Many people attempt to understand diagnostic codes to save money, but this usually proves frustrating if you don’t understand systems and parts specific to the make or model. This includes BMW’s Vanos engine valve control system. If you’ve never worked with BMW vehicles, which can be more complex than other cars, you may not understand what to do with the codes that result from a diagnostic test.
Furthermore, dealership technicians understand that error codes can suggest a problem but don’t necessarily indicate what is a problem. Experienced professionals can narrow down issues by ignoring irrelevant codes. Ultimately, this allows for greater efficiency when repairing a BMW. Dealerships also have access to the official diagnostic software that not only shows error codes but creates a plan to make and test repairs. From there, the dealership or another shop can perform maintenance.
BMW Parts and Systems Covered by Diagnostics
BMW diagnostics cover multiple systems, from basic engine functions to the comforts for drivers and passengers. Some of these systems may produce visible alert lights in your car. This includes the check engine light, MRS and SRS (airbags), ABS (anti-lock breaks), ASC (automatic stability control), and DCS (dynamic stability control) lights. However, those alerts may indicate one of multiple issues with each system, which is why diagnostics are important.
In addition to the system below, diagnostics can identify problems with onboard sensors, including cam, crank, thermostat, and engine temperature sensors.
- HVAC (climate control)
- Powered or heated seats
- Transmission and coolant systems
- Powered windows and locks
- Convertible roofs and sunroofs
- Vanos systems
- Lighting
- Steering and suspension
- Engines
- Alarms
- Alternators and batteries
- Electronics and charging
Other Computer Diagnostic and Programming Uses
Diagnostic hardware and software perform functions other than alerting you to possible problems. For example, computer diagnostics can also play a role when upgrading or fixing your vehicle. New parts need to be coded in. Otherwise, the diagnostic scanner may report errors. The errors don’t mean that a part was physically improperly installed, only that the computer isn’t reading the new part correctly.
BMW service technicians also use diagnostic software to reset service internals so that your BMW won’t unnecessarily alert you to the need to change the oil, for example.
