Volkswagen Petrol or Diesel Smell from Car — Top Causes

• Leaking fuel injector seal or O-ring dripping fuel onto the hot intake manifold — most common
• Perished fuel line or cracked fuel return pipe near the engine
• Fuel cap not sealing properly — allows EVAP vapour to escape into the engine bay
• Fuel tank vent valve (EVAP system) stuck open drawing raw fuel vapour into the cabin
• Over-rich running from a stuck-open injector causing unburnt fuel smell from exhaust

How We Diagnose Petrol or Diesel Smell from Car on Volkswagen

We use VCDS (Ross-Tech) to access all Volkswagen modules — engine ECU, transmission control unit, ABS, and body control. This gives us live data and fault codes that generic OBD readers miss on Volkswagen vehicles.

• Fuel system UV dye inspection under engine bay with UV lamp to locate leak source
• EVAP system leak test — pressurised with OEM smoke machine to find vent valve faults
• Injector balance test — identifies leaking or over-fuelling injector
• Fuel rail and return line pressure hold test for 10 minutes post-shutoff
