Offering incredible fuel economy perfect for long commutes, it is understandable why many Volkswagen and Audi TDI customers stay true to their mechanic’s repair schedule. Diligent TDI drivers keep up on everything from minor oil and filter services every 10,000 miles to timing-belt replacements every 120,000 miles, to keep their vehicle running at its best.

While commuters and drivers looking for overall fuel economy covet this turbo-direct-injection-diesel engine, which is often associated with Volkswagen and Audi, they still may be surprised to discover some key characteristics of their car.

Did you know …

1. A clean fuel filter is a must! Fuel filter services are due every 20,000 miles for TDI drivers. It keeps the high pressure side of the fuel system from getting particulates, or pieces of matter, inside the system and prevents excessive damage in the fuel system from said matter. Our team always primes your fuel system with Liqui Moly Diesel Purge, to TDIs running like new.

2. Use quality fluids. Just because you get 40 mpg, doesn’t mean you can overlook your fluids. TDI drivers should always use quality diesel fuel and the correct engine oil (VW 505.01 or VW507.00) to ensure their vehicle makes it to the 200,00+ mile mark without a major mechanical breakdown.

3. You can break the Audi/VW code - Modules in TDIs can be re-coded with a VCDS scan tool to unlock features of the car that aren’t normally available in the United States. These VCDS mods include controlling windows and sunroofs with a key fob or changing your day-time-running lights from your low beams to your fog lights, giving your VW or Audi a personal touch.

4. Your TDI transmission was born from Le Mans technology – Audi started racing diesels in 2005 at Le Mans, one of the most prestigious automobile races in the world often called the "Grand Prix of Endurance and Efficiency.” Inspirations from race to road are seen in the TDI transmission’s duel sequential gear box as well as the diesel engine and fuel system technology. After winning Le Mans in 2005, Audi began to integrate the technology into the road cars a few years later.

The TDI is an impressive and reliable vehicle and one worth taking care of. Make sure you find a reliable European shop that specializes in TDI repair and maintenance to get the most mileage out of your car.
