Rust Faults

The Punto Mk3 has a poor reputation for bodywork corrosion in the UK. Rear wheel arch lips and sill box sections corrode, often failing MOT on older examples.

EGR cooler failure is common on the B8 A4 TDI. Internal corrosion allows coolant to leak into the intake — initially causing rough running and white smoke.

EGR cooler failure on the Passat B7 2.0 TDI causes coolant loss and white smoke. The internal corrosion of the cooler allows coolant into the intake manifold.

The core plugs (freeze plugs) between the spark plugs rust, leaking coolant into the spark plug wells.

The mild steel exhaust back box rots through exceptionally quickly, often causing the exhaust to snap and drag on the floor.

The rear subframe on early Qashqais is highly susceptible to severe corrosion. It rusts from the inside out, leading to MOT failure and structural weakness.

The rear torsion beam axle on the Astra J corrodes in the UK climate. Surface rust progresses to structural corrosion on high-mileage or older examples, and is a common MOT advisory.

The Corsa E, like its predecessors, is susceptible to sill box section corrosion. UK salt and moisture attack the seam-welded sills from inside, causing bubbling and structural deterioration.

The Mk6 Fiesta is now 10+ years old and sill corrosion is increasingly common on UK examples. Bubbling paint along the sill seam and rear arch lip is a typical MOT failure point.

The rear torsion beam suspension on the Fiesta Mk7 is prone to surface corrosion and the trailing arm bushes wear, causing squeaking and vague rear end feel over bumps.
