VW Tiguan Start Stop Not Working
In order for the VW Tiguan start stop system to operate, the system first runs through certain checks. If one of these checks fail, the start stop system will not work. Possible reasons why the VW Tiguan start stop not working are:
- Driver’s seat belt is not worn.
- Driver’s door is not closed.
- The engine hood / bonnet is not closed.
- The engine must have reached minimum operating temperature. The start stop system will not work typically between the coolant temperature values of of below 10°C or above 100°C. This is reduced if the air temperature is less than 0°C.
- For versions of Volkswagen Tiguan with Climatronic, the temperature inside the vehicle must be within the pre-set temperature range and the humidity must not be too high. If the start stop system is not working, check temperature settings in the rear compartment.
- The windshield defrost function is switched on.
- On diesel versions of the Volkswagen Tiguan, the diesel temperature must not be too high; typically 60°C or greater.
- Diesel Particulate Filter (DPF) regeneration must not be taking place. Regeneration occurs when mainly short trips are taken in the vehicle.
- For versions of the Volkswagen Tiguan with a DSG gearbox, the gearbox oil temperature must not bee too low or too high. Typical values being below 0°C or above 118°C.
- The vehicle battery temperature must not be too low or too high. Typical values being below -5°C or above 60°C.
- The vehicle battery must have a minimum state of charge. Typical values being 75% or more for operation of the stop start system. Frequent short trips typically reduces battery charge. Leaving vehicle battery to charge overnight often helps.
- The vehicle is on a steep incline. This is usually around 9%.
- The vehicle is in reverse gear.
- The vehicle’s catalytic converter must not be too hot. This is in direct relation to engine coolant temperature.
- The vehicle’s ‘off-road’ mode has been selected.
