BMW SOS system Repair Geelong

‘SOS Call System Failure’ Error BMW – Let GERMAN CONNECTION resolve it.

If you’ve noticed the ‘Emergency call system not available’ or ‘SOS call system failure’ message on your BMW’s dashboard, you’re not alone. This issue is becoming increasingly common among BMW drivers in Geelong and is tied to the vehicle’s telematics system.

Understanding BMW’s Telematics System

BMW’s telematics module is an advanced safety feature designed to provide assistance in emergencies. It has two power sources:

The vehicle’s main power supply.
A dedicated backup battery.

This dual power setup ensures that even in the event of a severe accident resulting in complete power loss, the SOS function remains operational. The Telematic Communication Box (TCB) oversees the emergency battery’s health by performing an internal self-test during every start-up.

However, the backup battery has a limited lifespan. When its capacity diminishes to a level where it can no longer reliably place emergency calls, the system triggers a Check Control message, such as ‘Emergency call system fault’ or ‘SOS call system failure.’ Additionally, a fault entry is logged in the TCB.

What Causes the ‘SOS Call System Failure’ Error?

In most cases, this error is linked to the degradation of the telematics emergency call battery. Over time, the backup battery’s ability to hold a charge deteriorates, which prevents the emergency call system from functioning during power loss. This natural wear and tear is especially noticeable in colder climates, where batteries degrade faster. As a result, many BMW owners in Geelong report this issue more frequently during winter months.

Common Fault Codes

When diagnosing the problem, you may encounter the following fault codes:

B7F341: Emergency battery hardware faulty.
B7F343: Emergency battery charge interval reached.

BMW’s Warranty Policy and Repair Costs

Despite the importance of the emergency call system, BMW typically does not cover this fault beyond the standard Five-year warranty. The company classifies it as a wear-and-tear issue, leaving owners responsible for repair costs. This has sparked frustration among BMW drivers within Geelong, especially as dealership repair quotes often exceed $800 due to the labor-intensive process of replacing the battery, which is often located in the vehicle’s roof or in A Boot.
