Safety-critical vehicle advice should be treated as general discussion; use qualified repair help when a fault could make a vehicle unsafe.

General vehicle troubleshooting built around make, model, year, symptoms, codes and recent work. Do not treat forum advice as a substitute for qualified repair when a vehicle may be unsafe.

Community rules

  1. Give the vehicle details. Year, make, model, engine, codes and recent work should come before a diagnosis.
  2. Say when it should not be driven. Brake, steering, fuel and overheating issues can be safety critical.
  3. Diagnosis is not certainty. List likely checks and evidence instead of pretending a symptom has only one cause.
