Many of the Volkswagen Group range use direct injection, meaning injectors fitted directly into your cylinders. By having this set up and no injectors injecting fuel in the intake manifold spraying the intake valves with fuel keeping them clean, over time your intake valves will slowly build up an fair amount of carbon deposits, this will restrict air flow and in a lot of cases causing a major decrease in power for your vehicle.

Although we do sell a easy carbon cleaning solution in the way of our Forte Power Clean system, unlike a lot of carbon cleaning companies we know this does not work miracles, we know that most of our direct injection vehicles are too badly filled with carbon for this to work. So the actual fix for this is for us to remove your intake manifold and use our walnut blaster to safely clean the carbon from your valves. Once this has been done we are seeing quite a major increase in power on vehicles. Once we have carried out our walnut clean we then suggest having our Forte Power Clean carried out every 10,000-15,000 miles to stop your carbon building back up to a power restricting level.


A common issue on VWG vehicles (and many others!) is the direct injection injectors failing and causing misfires especially noticeable when tuning, we have invested in injector testing and cleaning equipment to allow us to test your injectors and clean as required to save you purchasing new injectors. This is highly recommended to be carried out at the same time as your intake clean due to us already being in the same place as the injectors whilst the intake is removed
