This involves meticulous checks of the timing belt, a component prone to wear that can lead to catastrophic engine failure if neglected.

Additionally, the RS6’s dynamic ride control (DRC) system, a marvel for handling, requires vigilant inspection to prevent the notorious leakage issues. Neglecting this system can lead to compromised performance and potential safety risks.

I don’t shy away from discussing the gearbox servicing – the Tiptronic transmission must undergo fluid and filter changes at prescribed intervals. This is crucial to maintain smooth shifting and prevent damage to the transmission.

As an enthusiast, I know these practices are paramount to maintain the RS6’s exhilarating performance and longevity. Proper maintenance not only ensures the car’s reliability but also preserves its value over time.

Common issues

My 2003 Audi RS6, despite its impressive features, often faces the common issue of failing ignition coils, leading to misfires and rough idling. This isn’t the only technical hiccup I’ve had to grapple with.

Here’s a quick rundown of the most persistent problems:

  1. Torque Converter Failures: The ZF 5HP24A transmission can suffer from premature torque converter wear, causing slipping and potential loss of drive.
  2. Leaking Valve Cover Gaskets: These are notorious for degrading over time, resulting in oil leaks and potential damage to the ignition components.
  3. Suspension Component Wear: The dynamic ride control (DRC) system is prone to leaks and the front upper control arms tend to wear out, affecting the car’s handling precision.

Staying ahead of these issues is key to maintaining the RS6’s performance edge.

Direct competitor

Despite its prowess, the 2003 Audi RS6 faces stiff competition, most notably from the BMW M5 of the same era. The E39 M5’s naturally aspirated 4.9L V8 S62 engine is a marvel, churning out an impressive 394 hp. This is slightly less than the RS6’s 4.2L bi-turbo V8, which produces 450 hp, but the M5 compensates with a more engaging driving experience, courtesy of its rear-wheel-drive layout and 6-speed manual transmission.

The M5’s precision steering and suspension tuning cater to those who prioritize handling dynamics over outright acceleration. In contrast, the RS6’s quattro AWD system provides superior traction, making it a formidable foe in various driving conditions.

Both vehicles exhibit masterful German engineering, but they cater to subtly different driver preferences within the high-performance luxury sedan niche.
