WHAT IS CARBON BUILD-UP?

Direct injection vehicles require a little extra care compared to the traditional port injection vehicles. Carbon build-up on Volkswagen direct injection engines is inevitable. Its just a matter of time until your vehicle starts losing the power it once had. If you notice your Volkswagen is starting to act sluggish, along with a loss in gas mileage, you are definitely in need of a carbon cleaning or “walnut blast.”

Traditional fueling, or port injection, sprays fuel on the valves which, in turn, continuously cleans the valves. Direct injection sprays the fuel directly into the cylinder, skipping right over the valves, leaving carbon build-up. These vehicles have countless pros when it comes to efficiency, this happens to be their only con.

Carbon build-up restricts air flow to the vehicle’s engine causing any number of the following problems:

  • Engine Misfire
  • Rough Idle at Cold Start
  • Engine Vibrates or Shakes
  • Check Engine Light

If you experience any of these drivability issues, give us a call.

WHAT’S INCLUDED IN THE REMOVAL?

Carbon cleaning begins with removing the intake manifold. We then clean the ports and intake valves via walnut blasting, which happens to be the best valve cleaning option on the market today. The walnut blasting process consists of using compressed air to inject walnut shell pieces onto the ports and valves. Carbon removal can be quite labor intensive depending on the size of the engine. Models and engines that may be affected by carbon build-up:
Any & all VWs with 1.8T or 2.0T, Golf, GTI, Passat, Jetta, CC, Tiguan, Rabbit 2.5L.

CAN YOU PREVENT IT?

There really is no cure to prevent carbon build-up from forming on your intake valves. It is best to treat carbon cleaning as part of your routine, mileage-based service. A walnut blast should be performed every 30,000 miles to keep you Volkswagen in the best shape and, most importantly, prevent any further engine problems.
