Case Study : BMW Battery Cell Module Replacement
A BMW vehicle arrived at our workshop displaying a drivetrain warning error, which we successfully reproduced under load in EV mode. Diagnostic testing identified a fault in Battery Cell Module Pack 4. Upon removal and inspection of the high-voltage battery, we confirmed three irreparable cells within the affected module.
We presented the customer with three repair options:
Option 1 – Targeted Module Replacement
Replace only the faulty module with a matched-condition unit. This was the most cost-effective solution and resolved the error. However, it would result in higher overall battery degradation and reduced range.
Option 2 – Full Pack Replacement with In-House Tested Modules
Replace all five battery cell modules using LKQ Electriq’s in-house tested packs. This offered improved range and performance compared to Option 1, while remaining significantly more affordable than sourcing new modules.
Option 3 – Full Pack Replacement with New BMW Modules
Replace all five modules with brand-new OEM units from BMW. This provided the highest possible range and performance but came at a premium cost.
The customer opted for Option 1, allowing us to return the vehicle to service quickly and cost-effectively, with no remaining drivetrain errors.

Case Study: BMW 530e High-Voltage Battery Repair
A BMW 530e was presented to LKQ Electriq with a drivetrain warning light and reduced electric range. The vehicle had previously been assessed by a BMW dealership, where the customer was advised to replace all battery cells with brand-new units – a costly solution.
Upon inspection, our technicians identified faults within battery module pack 4. We removed the high-voltage battery, bench-tested each module, and confirmed significant degradation across the pack. Although only one module was critically faulty, the overall condition of the battery warranted a more strategic approach.
Our Solution:
We fitted a high-quality, tested green part (used) battery pack, a cost-effective and sustainable alternative to full replacement. After installation, we carried out an End-of-Service (EOS) test and programmed the pack to the vehicle.
Results:
- Original Range (at purchase): 13 miles
- Range with fault: 8–9 miles
- Post-repair range: 20 miles
The vehicle, with 78,000 miles and two years of ownership, was returned to the customer fault-free and performing better than they’d experienced, demonstrating the effectiveness of our repair-first approach

Used BMW Battery Pack Example
As a result of this repair, the vehicle was fault-free with a better range than the customer had ever seen. The BMW had covered 78k miles and our customer had owned it for 2 years. Below is the difference in range:
When Purchased: The BMW had a 13 mile range
With The Fault: The BMW was getting 8-9 miles
After Our Repair: The BMW range increased to 20 miles
