Someone told me the other day that they live in Pleasaton, California, and they needed service on their diesel truck. Pleasanton is in the East San Francisco Bay, close to Left Coast Diesel or LCD in Livermore. If this location is inconvenient then perhaps the Concord shop will better suit you.
Pleasanton diesel service is just a short drive to Livermore, where the super capable technicians will give you better service than the dealer at more affordable rates.
