The Peugeot 406 is a highly regarded large family car produced from 1995 to 2004 (in Europe), known for its handsome design (especially the Pininfarina-designed Coupé), excellent ride comfort, and robust diesel engines. It was a significant success for Peugeot, particularly in the fleet market.
Overview
The 406 was developed on the same platform as the Citroën Xantia but without the complex hydropneumatic suspension. Its handling and ride quality were widely praised, with a sophisticated independent multi-link rear suspension that offered both comfort and stability. The car was available in three body styles: a 4-door saloon, a 5-door estate (SW), and a stylish 2-door coupé.
Common Problems & Reliability
The 406 is generally considered a reliable car, particularly with the 2.0 HDi diesel engine, which can last for very high mileages if well-maintained. However, there are a few known weaknesses.
Electrical Issues: Electrical gremlins are common, with reported issues including central locking faults (especially the boot lock), faulty indicator stalks, and dead pixels on dashboard displays.
Suspension and Brakes: The front suspension components, such as anti-roll bar links, may require replacement due to wear. The rear brakes on some models are also prone to rusting, and the parking brake is not always effective.
Engine Maintenance:
Timing Belt: Regular timing belt changes are crucial for all engines; failure to replace it at the recommended interval (around every 5 years or 60,000 miles) can cause significant engine damage.
Oil Leaks: V6 engines are robust but can suffer from oil leaks.
DPF Issues: On 2.2L HDi diesel models, the Diesel Particulate Filter (DPF) system requires regular maintenance and correct fluid levels to function properly.
Many owners praise the car for its durability, noting that regular maintenance and addressing wear-and-tear items are key to its longevity.
