Smell inside the cabin
A smell in the cabin can come from the ventilation, an exhaust leak or standing damp. When it appears is the first clue.
Possible causes
Exhaust
An exhaust leak near the cabin can let gases in. A smell of gas or smoke is a stop signal.
Standing damp
Water under the mats or in the spare wheel well keeps a damp smell going.
Questions to ask the garage
- Does the smell come from the ventilation or from outside?
- Was the cabin filter replaced?
- Was an exhaust leak search carried out?
Indicative preliminary diagnosis. Does not replace a vehicle inspection by a professional.
