| Description of the problem | Check engine light came on and triggered code reflecting misfires. Dealership checked out and it is a carbon buildup on intake valves. I am told this is a widespread problem with direct injection sytems especially on volkswagens, bmws, audis. The suggested fix is to have a shop or dealer remove manifold and use a media blast of walnut shells to remove the carbon. This will only last until the buildup comes back. This suv has approx 62,000 miles on it. The cost of getting the valves cleaned ranges anywhere from $400 to 1200. This problem is an inherent issue with design and there is nothing a consumeer can do to prevent it. As one repair shop said, it is inevitable and all direct injection engines will suffer this problem. I am appalled that there is no recall on this issue and when the dealer says it is a maintenance type item it really makes no sense to me. Proper maintenance should never include walnut blasting of carbon deposits on valves!!! Manufacturers need to step up and admit their mistakes and take responsibility for their design flaws. If i had been told when purchasing the car that you will need to do the media blasting at 60k, i certainly would not have made the purchase. |
