Which smell indicates an evaporative system fault?

  • A.An exhaust smell, which indicates that the vapour is being burnt rather than escaping to the atmosphere
  • B.Nothing
  • C.The odour of fuel near the vehicle when parked, which indicates vapour escaping rather than being captured
  • D.A petrol smell around a parked vehicle

Answer: D

A fuel smell around a parked vehicle means vapour is escaping. The last option explains exactly that, which makes it a correct and more instructive version. It should always be investigated. Reading the definition literally, rather than recalling a summary, avoids the usual confusion. The shared behaviour explains why these belong together and the differences explain why both exist. The quantity that varies and the quantity that does not are worth naming before any substitution is attempted.
