Recently, an Audizine forum member shared their experience with a seized Rs5 Audi Engine, providing valuable insights for owners and enthusiasts. The owner detailed the process of diagnosing and dismantling a high-mileage engine (98,000 miles) from a car they purchased in non-running condition. Upon inspection, despite the engine being difficult to turn even with a breaker bar, the valve train and cam chain guides appeared to be in good condition, better than some earlier Audi engine designs.

The root cause of the seized RS5 Audi engine was identified after removing the oil pan and lower assembly. The investigation revealed that the number four crankshaft rod journal, which supports the connecting rods for cylinders four and eight, had spun bearings. The damage patterns on the bearings strongly suggested oil contamination as the primary culprit. Although the car’s service history indicated regular maintenance at Audi dealerships, adhering to Audi’s recommended service intervals and oil specifications might not be sufficient to prevent this type of failure, especially at higher mileage.
This real-world example underscores the intricate nature of the RS5 Audi engine and the critical role of proper lubrication. While the owner was relieved to find no apparent design flaws in the engine itself, the incident serves as a potent reminder for all RS5 Audi engine owners: prioritize preventative maintenance. Regular oil and filter changes, performed more frequently than Audi’s standard recommendations, are crucial. Using top-quality oil and ensuring air filters are changed regularly to prevent dirt and contaminants from entering the engine are also vital steps in safeguarding the longevity and performance of your RS5 Audi engine. This proactive approach to maintenance can significantly reduce the risk of costly engine failures related to oil contamination and ensure continued driving pleasure.
