Expert Diesel Repair and Maintenance

Is your Volkswagen TDI not as peppy as it should be? Check engine light on in your CRD Liberty? When was the last time you had a valve adjustment on your diesel Mercedes or a timing belt replacement on your diesel Volvo? Dr. Dan’s provides complete diesel auto repair, specializing in TDI’s and older Volvo/VW/Audi and Mercedes diesels, as well as Sprinter vans, CRD Jeeps, and, when we have space, the occasional Cummins or Powerstroke truck.

Diesels are Different

Diesels are unique from gasoline vehicles and require a specific set of skills, knowledge and equipment for all but the most basic repairs. Because diesels comprise a very small percentage of vehicles on American roads, few independent shops are able to offer the levels of specialization and particular expertise necessary for diesel work, while dealership service departments are costly and often no more competent with getting a diesel fixed correctly. One of the hardships of owning a diesel can be the difficulty of finding a mechanic who has the ability to give your vehicle the care it needs, let alone one who can also earn your trust and keep an eye on your bottom line. Fortunately, if you are a diesel owner in the Seattle area, that is a problem that you will not have!

Dr. Dan’s offers years of experience with diesel diagnosis and repair, along with the proper special tools, OEM-quality parts, and specialized knowledge that are essential for high-level TDI and diesel service. Whether it’s a timing belt replacement, check engine light, low power diagnosis, or just a routine oil change, we can keep your diesel car or truck on the road and running efficiently, smoothly, and reliably while delivering the highest standards of workmanship and quality — without charging dealership prices.

One-offs, uncommon vehicles, modifications

Have a rare or older diesel vehicle that needs service? We have experience working on nearly every type of diesel, no matter how rare — from TDI Vanagon conversions, to old Peugeots, to International Scouts and older Mazda/Datsun/Isuzu/Toyota cars and trucks, to foreign-market BMW diesels and diesel Land Cruisers… even a right hand drive diesel-powered British London Taxi. If it has a diesel engine under the hood, chances are we know how to fix it (or at least will be able to figure it out). If you have an oddball vehicle you want to bring in, call us to discuss beforehand as we may need to budget additional time for gathering hard-to-find parts, tools, or information.

Service appointments

Want to set up a time to bring your car in? Service is by appointment; call us at 206-783-5728 to get on the schedule! (Yes, we will work on your diesel even if it does not have biodiesel in the tank.) We try to maintain a personal relationship with each of our customers and their vehicles, so if you are a new customer, coming in for an initial look-over and check-up is a good way for us to get acquainted with you and your car and get a baseline on where it sits.

We look forward to serving you and your diesel’s needs. Thanks!
