The Volkswagen Walnut Blasting Decarbonizer uses walnut shells to gently remove carbon build-up in the engine for a cleaner and smoother drive. Recognized and approved by Volkswagen AG, this method is economical, efficient and non-corrosive, without the use of harmful chemicals.

All cars with a direct injection engine that runs on gasoline will produce carbon deposits as a by-product of the combustion process which can lead to sluggish engine performance. This is aggravated by stop-and-go city driving. Over the years, this causes a build-up of black soot that hardens around the intake valves. The build-up causes restrictions in the engine, resulting in loss of power, overheating and higher fuel consumption. Aside from the Electronic Power Control and Engine Warning lights, other symptoms are rough idling, poor acceleration, engine misfire and knocking sounds.

Erik Winter, Managing Director of Volkswagen Passenger Cars Malaysia said that this service addition is part of the ongoing effort under the Volkswagen Cares promise. "It goes without saying that our customers are our top priority - and we are continuously looking for ways to improve our services and offerings to our customers under the VW Cares brand promise to provide value-added and quality services. This is one of many to come." 

Volkswagen owners are advised to decarbonize their engines every 45,000km as a preventive measure and can seek further assistance from all authorized dealerships.
