Overview
BMW uses AI-powered cameras and sensors to identify assembly errors during vehicle manufacturing.
Intelligent inspection systems distinguish genuine defects from harmless variations, reducing unnecessary manual checks.
Generative AI helps tailor quality inspections to individual vehicle specifications and production data.
BMW Group is using artificial intelligence (AI) to improve quality inspections across its vehicle manufacturing operations, with systems designed to identify assembly errors, detect visual defects, and help workers address problems before vehicles leave the production line.
The German automaker has integrated AI into its BMW iFACTORY production strategy, combining cameras, sensors, machine learning, and real-time data analysis to make manufacturing more reliable. Its AI Quality Next (AIQX) platform analyses images and sensor data to identify deviations during assembly and provide immediate feedback to production employees.
This approach reflects a broader shift in automotive manufacturing, where AI is used not only to automate repetitive inspections but also to help workers spot problems earlier in the production process.
How BMW's AIQX System Detects Manufacturing Defect
AIQX, an abbreviation for Artificial Intelligence Quality Next, uses cameras along the production line to monitor specific components and features of cars during assembly.
AIQX uses deep learning-based computer vision to analyze images taken from the production line. These images are analyzed using cloud-based platforms, where software algorithms trained on correct and incorrect component examples look for deviations.
This technology can verify that all components are installed correctly, detect missing parts, and check discrepancies in the car assembly process. For example, it can check the BMW logo on a car's bonnet and whether the doors are locked.
As reported by BMW Group, this technology gives employees instant feedback via smart devices, allowing them to verify the situation immediately and fix potential mistakes during car assembly. In addition, BMW has developed a cloud-based technology called Car2X that allows cars on the production line to communicate with production systems.
AI Helps Reduce False Defect Alerts
Inspection systems in manufacturing should be able to distinguish between a defect and harmless variations. Dust particles, oil particles, and other surface features can look like cracks and other defects, leading to unnecessary inspections.
BMW has used AI technology to solve this issue at its Dingolfing factory in Germany. In press shop operations, AI systems analyze images of metal parts and distinguish real defects from non-defect variations, such as dust particles and oil droplets.
The system uses labeled images for different conditions and can recognize patterns that traditional inspection methods cannot identify.
Eliminating false alerts could reduce unnecessary tests and inspections. Additionally, it would allow the quality control department to focus on potential defects in the car.
BMW has used similar analytic methods to analyze engine tests at its Steyr factory using software based on recorded tests.
AI Expands Beyond Visual Inspection
BMW's use of AI extends beyond cameras and image recognition. At its Dingolfing plant, the company uses Acoustic Analytics, part of AIQX, to perform automated, audio-based quality checks.
The system analyses sounds produced during vehicle testing to identify unwanted noises that could indicate a problem. This is particularly useful during final checks, when vehicles undergo assessments before being handed over to customers.
AI is also being applied to painted vehicle surfaces. At BMW Group Plant Regensburg, automated surface processing combines AI-based inspection with robotic systems to assess and treat painted surfaces according to defined quality standards.
These applications show how manufacturers can combine different data types to identify problems that conventional visual inspection alone may miss.

BMW Tests AI-Generated Quality Checks
BMW is also exploring how generative AI can make vehicle inspections more specific to individual vehicles.
In April 2025, the corporation presented the GenAI4Q pilot at Plant Regensburg. This system offers customized inspection suggestions for about 1,400 cars produced every day.
This plant manufactures cars with various engine types, equipment sets, and customer configurations on one assembly line. The plant assembles a new car every 57 seconds.
Using information about the vehicle specifications and the production process, the AI system decides which inspections to perform on each specific car.
Then, it organizes this information into an inspection catalog accessible via a smartphone application. BMW has been working on this project together with the Munich-based start-up Datagon AI.

What AI Means for Automotive Manufacturing
BMW's example shows how AI can support quality control at different stages of car manufacturing, from assembling parts to final checks.
AI will assist in early detection of deviations, reduce repetitive checks, and minimize unnecessary tests caused by false alarms. The technology will also provide employees with more accurate information when investigating problems.
Nevertheless, AI cannot replace human skills. Inspection technologies rely on accurate datasets, appropriate sensors, and quality criteria. Employees will be needed to interpret the results and solve more complex cases.
BMW's task is to combine AI with experience gained during the production process. As vehicle manufacturing becomes increasingly digitized, AI-assisted quality control is expected to gain even more importance.
