Audi A6 C4 1.9 TDI: A Comprehensive Buyer's Guide

Introduction

The Audi A6 is a mid-size executive car that has been in production since the 1990s. The C4 generation of the A6, produced from 1997 to 2004, was powered by various engines, including the popular 1.9 TDI diesel unit. If you're considering purchasing an Audi A6 C4 with a 1.9 TDI engine, this guide will provide you with detailed information on what to look for, prices, and running costs.

Engine and Performance

The 1.9 TDI engine is a turbocharged diesel inline-four cylinder that produces 90 horsepower (66 kW) at 3,500 rpm and 170 Nm of torque at 2,000-4,500 rpm. The engine features a timing belt-driven system with a fuel-injection pump driven by the camshaft. This configuration allows for relatively low maintenance costs.

On paper, the A6 C4's performance figures might seem modest compared to modern cars. However, in its time, it offered respectable acceleration and was known for its impressive towing capacity. In real-world driving conditions, you can expect:

• 0-60 mph (97 km/h) in approximately 12 seconds
• Top speed electronically limited to around 115 mph (185 km/h)
• Smooth and relatively quiet operation due to the turbocharger

Transmission and Gearbox

The A6 C4's transmission is a five-speed manual, which is still considered quite modern for its age. The manual transmission offers smooth shifting and precise control. Additionally, an automatic four-speed Tiptronic transmission was available as an option.

While some owners have reported issues with the five-speed manual's synchronizers wearing out over time, this problem can be addressed by regular maintenance (every 12,000 miles or more frequently if conditions are extreme).

Interior and Comfort

The C4 A6 interior is known for its premium feel and modern design. You'll find plenty of standard features, including:

• Dual-zone climate control
• Heated and adjustable front seats with lumbar support
• A leather-wrapped steering wheel and gearshift
• CD player with an MP3 compatible auxiliary input (optional)

The cabin space is generous, offering sufficient room for passengers and cargo. Although the rear legroom might be considered somewhat limited compared to some modern executive cars, it still provides adequate comfort for short trips or everyday errands.
