Tailgate Rust (Wagons)

Symptoms

Rust along the bottom edge of the tailgate, especially around the number plate lights and lower corners.

Cause

Water sits in the tailgate frame and rots it from the inside out.

Fix

Cut and weld, or replace the tailgate. Used tailgates are cheap ($100-200), but check them carefully, they all rust in the same spots.

Cost mentioned in fix
$100-200

Other known issues

Common Body and Rust

Rear Wheel Arches and Sills

Rust bubbles, holes, or structural rot in the rear wheel arches, sills, and inner arches.
Critical Body and Rust

Subframe Corrosion

The rear subframe (where the trailing arms mount) rusts through. This is catastrophic if it lets go.
Common Engine

PCV System Oil Leaks and Breather Box Failures

Oil everywhere, particularly around the back of the engine and firewall. You might see smoke at idle or a rough idle. In severe cases, the turbo oil feed line can blow apart because the crankcase is pressurised like a balloon.
Critical Engine

Timing Belt and Water Pump

The engine suddenly stops. If you're lucky, nothing else happens. If you're not, you've just destroyed pistons, valves, and possibly the head. This is an interference engine.
Critical Engine

Oil Consumption (Turbocharged Models)

You're adding a litre of oil every 1000-2000 km. Blue smoke on startup or under boost.
Common Engine

Turbo Failure (T5 and 850R)

Loss of power, screaming noises, oily exhaust smoke. The car feels gutless and the boost gauge stays flat.
