You can adjust your valves and clean your injectors yourself, it is not difficult to do and does not require any special equipment. Do it next weekend. If you do not have a healthy diesel clatter you may want to set the timing on the injection pump as well. The ease of maintenance is one of the benefits of owning this car. The performance of this car may have some more surprises in store for you.
