Carbon Cleaning Service

Cleaning carbon buildup left behind from direct injection vehicles.

Volkswagen and Audi 2.0T Carbon Buildup Cleaning Service

What is direct injection? And what are some of the pros and cons of this newer technology? Direct injection sprays fuel directly into the combustion chamber instead of into the intake track. This is a faster and more efficient way to get fuel into the cylinders which leads to better fuel economy and cleaner emissions. With any advancement in technology comes great benefit, but you also see the negative effects too. In this case… carbon buildup. By spraying fuel directly into the cylinders you lose the ability to lubricate the valves like older model vehicles.


What are some possible troubles or  symptoms you may experience in a car that has significant carbon build up?

  • Rough Idle
  • Low power
  • Slow Acceleration
  • Misfires
  • Poor Fuel Economy

What is the common fix to these issues?

We highly recommend bringing us the car to be diagnosed by a professional. There are many parts to this car that share similar symptoms so pulling the car apart to perform this service might not be all that is needed. We highly recommend a cleaning service before running into issues like those noted above, typically around 60k miles is when we recommend having the valves cleaned. By pulling off the intake manifold you gain access to the valves to clean them. This is the most thorough process to cleaning the buildup off the valves and Excelerate Performance as made a tool specifically for this service to make sure it is done right.

Excelerate is awesome for all kinds of work on German cars. I had work done on my Audi and will definitely be back for more. Their mechanics go the extra mile and seem more qualified than most dealership services. I highly recommend them!

Austin says:

Spoke to the service manager about a problem I’m having with my 2010 Volkswagen Passat. The gentleman I spoke to was extremely knowledgable and helpful with my problem. I’ve spoken to many repair shops about it and nobody describe it as well as these guys. I know have a better idea of where to go from here just from speaking with him for about 5 minutes. Great customer service. Sad I’m across the country or I would 100% bring my vw here!
