When considering a used Audi A4 1.8 TFSI Executive SE Euro 4 4dr, it’s important to carefully assess several key factors to ensure you're making a wise purchase. Start by reviewing the car’s history and documentation. Obtain the service records to confirm it has been regularly maintained, particularly for key components like the turbocharger and timing belt, which are crucial for the performance of the 1.8 TFSI engine. Check the MOT history for any recurring issues or advisories, and conduct an HPI check to ensure the car is free from any outstanding finance, theft reports, or write-offs.

Given that this is a Euro 4-compliant model, it may not be eligible for some low-emission zone exemptions, so confirm whether this is a concern in your area. During a test drive, ensure the 1.8 TFSI engine runs smoothly, delivering power without any unusual noises or hesitation. The turbo should engage seamlessly, and the six-speed manual transmission (or automatic, depending on the version) should shift smoothly with no jerks. Check for any warning lights on the dashboard, and ensure the car idles evenly without roughness or excessive exhaust smoke.

Thoroughly inspect the car’s mechanical and cosmetic condition. The bodywork should be free of dents, scratches, or rust, particularly on older models where corrosion could be a concern. Examine the tires for even wear and sufficient tread depth. Inside, check the interior for wear on the seats, steering wheel, and dashboard, as these are common areas of use. Verify that the infotainment system, air conditioning, and other features like power windows and mirrors are working properly.

The Audi A4 1.8 TFSI Executive SE is known for offering a premium driving experience, so during the test drive, pay attention to the suspension and handling, ensuring a comfortable and smooth ride. Check that the brakes function effectively without any grinding noises or vibrations, and that the steering is responsive and aligned.

Mileage and age are important factors in determining the car's value. A lower-mileage example is ideal, but high-mileage vehicles can still offer value if they have been well-maintained. The average mileage for cars of this age should be around 10,000-12,000 miles per year. Compare the asking price with similar vehicles on the market to ensure the car is competitively priced, and use any minor issues or imperfections to negotiate a better deal.

Lastly, consider ongoing costs, including road tax, insurance, and maintenance. The 1.8 TFSI engine is generally fuel-efficient for a car of its size, achieving around 35-40 MPG in mixed driving. However, keep in mind that the Euro 4 compliance may lead to higher road tax in comparison to newer, cleaner models. If available, inquire about any extended warranties or after-sales support to ensure peace of mind in case of any mechanical issues.

The Audi A4 1.8 TFSI Executive SE Euro 4 4dr is a well-built, stylish vehicle that offers a great balance of performance, comfort, and luxury. However, it’s essential to ensure the car has been well-maintained and that the price is right for its age and condition.
