Common Body and Rust

Windscreen and sunroof rust

Symptoms

Rust around the windscreen surround or sunroof frame. Water leaks into the cabin.

Cause

Water sits in the windscreen surround and corrodes from the inside out. Sunroof drains block, and water overflows into the roof structure.

Fix

Windscreen rust requires cutting out the rot and welding in new metal before refitting the screen.

Sunroof drains can be cleared with compressed air or a length of wire, do this annually.

If the frame is rusted, it's a big repair.

Other known issues

Common Body and Rust

Sills, rear arches, and tailgate (wagons)

Rust bubbling through paint, holes appearing, or structural weakness. Wagons suffer worst around the tailgate lower corners and rear wheel arches.

Minor Body and Rust

Door and bonnet hinges sagging

Doors or bonnet don't align properly, hard to close, or rattle.

Critical Engine

Oil leaks everywhere

You'll find oil pooling under the car, dripping from the valve cover, front and rear main seals, cam seals, or oil cooler lines. The B230 engines (940) and B6304 (960) both weep oil as they age, it's not if, it's when.

Common Engine

Flame trap and PCV system clogged

Engine bogs down, idles rough, struggles to rev, or won't start when hot. You might get excessive crankcase pressure, blowing out seals and pushing oil into the intake.

Critical Engine

Rough idle, hesitation, or won't start (fuel system issues)

Stumbling acceleration, poor fuel economy, hard starting, or stalling. Sometimes it runs fine cold but misfires when warm. Check engine light may be on or flashing.

Critical Engine

Timing belt and waterpump failures

Catastrophic engine damage if the belt snaps. You'll hear grinding, the engine stops instantly, and you're looking at bent valves or worse. Waterpump failure shows as overheating or coolant leaks from the front of the engine.
