Diagnosing issues with your BMW

A BMW owner becomes one with their BMW. These are exquisite, well-made vehicles and for the owner of a BMW, they are more than just a mode of transportation.  Most BWMW owners are in sync and in tune with their BMW, so when it is driving or braking differently, or has sounds that aren’t common, they know something isn’t right. They may not know the specific BMW diagnostics, but they know something isn’t as it should be, and that the vehicle needs to be inspected by their mechanic. 

Every BMW made today is equipped with computer microchips, processors, and sensors which are linked to an internal computer that create  information from the BMW diagnostics.   With a BMW diagnostics kit , that computer can tell a mechanic what is wrong with a BMW when the owner brings the car to them with a light on the dashboard or concerned that it doesn’t have the power it should when driving. The BMW diagnostics tool is connected to the car’s computer and runs a scan on the operating system.  

How do you scan a BMW?

How long does a diagnostic test take for a car?

Today, the tools used to scan and read BMW diagnostics are instrumental in a mechanic being able to isolate the problems. However, even though the tools used to read a BMW diagnostics are helpful, there are some instances that even with the BMW diagnostics rans, the mechanic may not be able to determine the cause and problem that the dashboard lights are indicating, or why a BMW broke down. 

The time for standard diagnostic testing will typically take between one to two hours. If there are more complicated problems, further BMW diagnostics is needed, and some components may need to be removed for the mechanic to gain access for further testing. In this case, BMW diagnostics can take up to three hours depending on the issue and its severity or if multiple issues are discovered that were underlying of what would be obvious. 

What is the best diagnostic tool for BMW?

Professional mechanics trained to service a BMW will likely have a BMW diagnostics tool the prefer or the dealership provides one they want used. If you’re a car enthusiast that prefers to work on your own BMW, or you’re looking for a way to save some money, the scan tool used by BMW mechanics is priceless in value. You don’t have to choose the most expensive one either, because over time, regardless what you spend on a BMW diagnostics tool, you’ll find that it is worth the investment. 

A BMW diagnostics tool is referred to as an OBD machine. OBD is abbreviated for on-board-diagnostics and is a  code reader that gives your mechanic, or you, the ability to check and troubleshoot the various features and systems of your BMW.  The OBD can scan the airbag, anti-lock brake system, engine, transmission, and other components. Here we list what we consider to be the three best BMW diagnostics tools:  

  • BlueDriver Bluetooth Professional OBDII Scanner: It is considered by mechanics to be the best for affordability and provides the professional diagnostics needed. Although this unit does not have a built-in screen, it will transmit your BMW diagnostics data to your mobile device which probably has a better screen resolution.

Additionally, BMW remote diagnostics are possible by a BMW mechanic if the owner of the vehicles activates two services through their iDrive operating system installed at the BMW factor and are for BMW use only: 

  • BMW Teleservices Diagnosis
  • BMW Teleservices Assistance

How do you read BMW codes without a scanner?

Yes, but it is more time consuming and needs total attention and concentration. Flicking the car’s ignition on and off quickly without cranking it will flash trouble codes on the dash or a service light for a specific function will stay lit with the words “service engine”.       

For what they cost, shouldn’t BMW diagnostics be done free of charge? Does BMW do free diagnostics? Unfortunately, no, in most cases a BMW dealership will not run BMW diagnostics for free. In the case that car is within a few days of purchase, they may run BMW diagnostics at no charge. In most cases, because they know these are well engineered vehicles, they will charge for a professional check of your BMW diagnostics. Need help with your BMW in Dallas, TX? Call 469-904-0734 today.
