Your air conditioning system can lose up to 10 per cent of its gas each year. Unless it's replaced the system will be less able to keep you cool and refreshed.
The system will continue to lose gas, become less efficient and lead to increased fuel consumption. It will eventually fail and need replacement parts.
We drain and recharge the system; check hoses, filters, belts and connections; and make sure the compressor and condenser are working correctly.
Volkswagen recommends every 2 years.
