Summary Verdict

The 2006 BMW 325xi offers a compelling blend of performance and luxury, but potential buyers should be aware of common issues. The N52 engine, while generally robust, is prone to oil leaks from the valve cover gasket and PCV system failures, along with significant cooling system component failures like the water pump and thermostat. Automatic transmissions can experience issues with the mechatronic sleeve. Electrically, power steering failure and window regulator problems are notable. While the manual transmission and suspension are typically reliable, the electrical and powertrain components warrant careful inspection and consideration of potential repair costs. Regular maintenance is crucial for mitigating these issues.
