Direct-injection engines (GDI, FSI, TDI, TFSI) have no oil film on the intake valves — so carbon builds up quickly, causing rough idle, vibration and power loss. Walnut blasting is the most effective way to remove these deposits without disassembling the engine — a stream of finely ground walnut shells blasts off the carbon without damaging the metal. After the clean the engine runs smoother, more powerfully and more efficiently.

Yes, we offer intake valve cleaning using the walnut blasting method for direct injection engines. This process effectively removes carbon deposits and build-up without requiring engine disassembly. To schedule an appointment, please contact us in writing via WhatsApp or through the 'Appointment Request' form on our website. Kindly provide your vehicle details, and we will send you a written confirmation.
An intake cleaning is recommended based on the engine's symptoms rather than a specific mileage. If you notice a rough idle, vibrations, or a noticeable loss of power in your direct-injection vehicle, these are typical signs of significant deposits. A cleaning can then be beneficial to restore engine performance and efficiency. We are happy to assess the condition based on your description of the symptoms.
The main benefit is the restoration of the engine's original performance and smoothness. By removing carbon deposits from the intake valves, the engine runs more evenly, responds better to the accelerator, and can also become more fuel-efficient. It is an important preventative measure to maintain the longevity and efficiency of direct-injection engines such as FSI, TDI, or TFSI.
Walnut blasting is the most effective and gentle method for removing stubborn carbon deposits. The finely ground walnut shell granulate thoroughly cleans the metal surfaces of the valves and intake tract without damaging them. Furthermore, the cylinder head does not need to be removed for this cleaning, making the procedure efficient and safe for the engine compared to mechanical alternatives.
