If you are a BMW or MINI owner this post is for you.
Walnut Blasting is a dealer recommended service for BMW and MINI owners every 30,000 miles.
What’s the issue?
Direct injection BMW engines are prone to excessive carbon build up on the vehicle’s intake valves. Your N54’s intake system needs to be cleaned regularly to perform at it’s peak. This buildup is common and normal but as the level increases you could find your car suffering from a few of the following issues:
Why does this happen?
The most common reason for the carbon build up is due to contaminants in the air that pass across the engine’s intake valves. In a multi-port injection engine, fuel is injected prior to the intake valves, which allows the fuel to clean the buildup that accumulates on the intake ports and valves. Contaminants in the air mixture are then carried into the cylinder with the fuel to be burnt.
In BMW’s direct injection engine, fuel is injected directly into the cylinder. This causes the oil and carbon contaminants to collect on the valve. Over time, the engine is slowly restricted of useable air, which is why this service is needed.
Is there anything to do to prevent the build up?
Unfortunately, no. There are some ways to postpone the problem but it can’t be fully eliminated.
