Audi carbon cleaning service – Should I do it?

What is a carbon cleaning service and why do I need it for my Audi?

Gasoline direct-injection technology allows gasoline engines to burn fuel more efficiently. This results in more power, cleaner emissions and increased fuel economy. The benefits of direct-injection are well documented, the downside of this technology is the potential of carbon build-up can occur. This build-up affects the way air enters the combustion chamber and causes many symptoms. These include (but are not limited to): misfiring, rough idle when cold, lost horsepower and poor fuel economy. Over time/miles the carbon deposits inside the engine, so it is time to perform an Audi carbon cleaning service.

Direct-injected engines from Audi – FSI, TSI, and TFSI – are prone to carbon build-up in the intake ports and on the intake valves. This build-up becomes severely detrimental to engine performance and efficiency. These deposits worsen over time, inhibit airflow and can even break off and fall into the intake tract. As a result, they can cause damage to the valves, catalytic converters and other engine components. 

When the carbon build-up gets to a severe stage you can see misfire fault codes sporadically. They usually happen when the car is cold. As a result, the check engine light will turn on. You might also experience a decrease in your fuel mileage, reduction in engine power and poor idle.

At Bestiale, one of our main goals is to help our customers to maintain their Audi in the most efficient way possible (according to Audi manuals). Therefore, we highly recommend to our clients to do carbon cleaning service to their Audi engines regularly. 
Some of the latest engines have port and direct injection to eliminate the carbon build-up. Feel free to contact us if you need help with checking your type of engine.

What do we do?

We perform Audi carbon cleaning service port-by-port, using a combination of walnut shell blasting and liquid solvents. Audi carbon cleaning service is done by removing the intake manifold and blasting it with walnut shells. In this way, we will clean away all of the carbon build-up and your car will perform like new. The walnut shells are softer than aluminum so there is no damage to parts at all. Then we use liquid solvents to clean that hard to reach parts and finish the cleaning.

In our experience, this is the most effective method to completely clean the carbon build-up and to slow down its accumulation. We rotate the engine so that the corresponding intake valves are closed. This ensures that no debris fall into the combustion chamber. We ensure that all seals/gaskets/hardware that are one-time use are replaced with OE/OEM high-quality parts. The carbon cleaning should be done every 20k – 80k miles depending on conditions, engine type (e.g. the RS4 V8 engine is more prone to it) and desire for perfection.

How much Audi carbon cleaning service cost?

For every Audi, the cost of a carbon cleaning service is different. It depends on the model of your Audi and the engine size. The cost depends on also if we have to remove the fuel injectors or not. Sometimes the repair kit for the fuel injectors (valve units) could have a big impact on the final cost.

We highly recommend at the same time, to replace the oil separator and possibly the fuel injectors. This helps in preventing faster carbon build-up on your intake valves.
