Buying Tips for 1990 Volkswagen Golf Mk4 (1J)
- Check central locking on all doors—the microswitch failures are the most common annoyance and an MOT security risk.
- Ensure windows don't rattle or drop (regulator failure); test all four up and down.
- Inspect the rear wiper for leaks into the boot latch, which can cause electrical shorts.
- Check the front wheel arches for bubbling paint—moisture-trapping foam pads behind the liners cause hidden corrosion.
- Verify the timing belt and water pump have been changed every 4–5 years; a snapped belt means engine death.
- On 1.8T models, check oil consumption and turbo boost—the turbo can fail if oil changes have been neglected.
