BMW MRS and SRS

BMW MRS and SRS

A common occurrence with late-model BMW’s is the air bag warning light. More than likely you’ve encountered this problem with your BMW. Often the light will say on then go away after a few minutes of driving, sometimes it will blink and stay on or it will simply stay on from the time you start your vehicle. Either way, any of these issues can be annoying and is a sign that your airbag computer (SRS or Supplemental Restraint System) has had a problem. Often triggered by minor events which require no maintenance. These incidents have been known to trigger a false positive reading within the computer causing the light to go on. Driving your BMW through large puddles or being exposed to heavy rains Changing steering wheels Replacing bulbs behind the gauge cluster Track or aggressive driving Temporarily disconnecting the SRS (often done during an alarm or stereo installation) Removing the SRS fuse Bad seatbelt sensor or belt receptacle (most common) You can’t clear ... read more

What is a BMW Diagnostic Scan?

What is a BMW Diagnostic Scan?

A BMW ISTA diagnostic scan (or test) allows us to analyze the control units installed on your vehicle, their variants and other special equipment. The scan reads the diagnostic and service-related data in the BMW control units. A test plan is generated which becomes part of the service procedure. The test plan lists suspected vehicle components and functions according to priority. The suspected components and functions are displayed  with documentation and procedures providing a localized fault and how to fix the issue. A procedure (service program) is designed to find the cause of the failure. Using the procedures and fault plan, your technician can identify and fix the issue. Once this procedure has been addressed, further tests will be conducted to see if further issues persist. As a BMW repair facility for the last 35 years I Brooklyn, we have the factory tools and training to identify any BMW vehicle issue. If you suspect your ... read more

BMW Intelligent Battery Sensor (IBS)

BMW Intelligent Battery Sensor (IBS)

On newer BMW’s you will find the Intelligent Battery Sensor (IBS). This component monitors and measures your battery performance. The software calculates your “state of charge” and “state of health” of your battery whether your vehicle is on or off. It’s important to know that this sensor can easily be damaged by improper handling. Removing the battery cable roughly or water leaks can simply damage the sensor causing false readings. The IBS manages power consumption and a faulty reading can cause other electronics to be limited or switched off as the computer thinks there is an issue with the battery. The IBS system charges your battery when needed, allowing your battery to consistently stay at optimal performance. How do you know if your BMW as IBS? Knowing the warning signs of a bad IBS sensor can save you money on new battery replacement. Often times BMW owners think their battery is dead due to a bad battery. They replace the battery not unde ... read more

BMW Battery Registration

BMW’s that are equipped with an IBS (Intelligent Battery Sensor) measure battery capacity and notify you when it needs to be replaced. You need to registrar battery replacements. Why register your new battery? The electrical system of BMW’s after 2002 became very sophisticated. After you install a new battery, the service function “Register Battery Replacement” must be completed. BMW vehicles with IBS inform the power management software (software in the electronics and intelligent battery sensor) must know in order to properly function the power management in your vehicle. Not doing so will lead to limited electrical functions or functions being turned off to conserve power. Additionally the system will try to recharge the new batter, causing premature failure of your new battery. Can you perform the “Register Battery Replacement” yourself? BMW vehicles require factory specific scanners to talk with your vehicles computer. If you have the ... read more

BMW Coding & Programming - Do you know the difference?

BMW Coding & Programming - Do you know the difference?

What is BMW Coding? BMW coding is the process in which BMW groups system specific operating requirement (data) together the assigns code or labels to each data groups. Those data groups are then pre-loaded into “codable” modules along with a simple set of operation instructions. Operation requirement types can be O2 sensors, emissions controls, fuel type, Manual or Auto transmissions. The procedure to assign groups of data to the operation program of a specific control module/component is known as coding. A codable control module has basic operation programs pre-installed along with specific variations. The process allows you to change the basic operation of a module/component on your vehicle.  With BMW coding, you’re able to make minor changes to your vehicles software to unlock features BMW makes available in some of its vehicles.  What is BMW Programming? BMW programming is a more complex version of coding. While coding refers to minor changes of exi ... read more
