Petrol Golf Cabriolet maintenance (TSI and non-turbo petrol)
Petrol Golf Cabriolet engines range from earlier non-turbo units to later TSI turbocharged options, so the right service plan depends on which engine you have. Regular engine oil and filter changes are key for turbocharger longevity on TSI engines such as 1.2 TSI, 1.4 TSI and 2.0 TSI, and it is worth checking for oil leaks and deterioration in hoses at each service. Spark plugs and ignition components are typical petrol service items, and misfires can often show up first as rough running under load. Cooling system condition also matters on both older and newer petrol engines, so keep an eye on coolant level and any signs of overheating.
