"Your VW and Audi Experts in Sioux Falls, SD"

VW and Audi Owners, here are few service and maintenance tips:


  • Fuel Injector Flush
    Stop spending your money on unnecessary work that your car does not need. Have you ever been told that your vehicle needs a Fuel Injector Flush for greater MPG? WRONG!!! ...from our in house testing there is not proof of any MPG improvement due to cleaning injectors using fuel injector flush products.

  • Cooling System Flush
    How about those cooling system flushes? Most VW and Audi's are using lifetime coolant. Unless the Coolant is contaminated or the system has been opened due to repairs, the coolant does not need to be replaced. For all VW/Audi vehicles we strongly suggest using only OEM G12 Coolant to keep your vehicles cooling system in proper working condition.

  • Check Engine Light
    The check engine light comes on when the on-board computer detects a fault in engine drive-ability or performance, transmission control system or transmission, or the emissions system, and a fault code is set and stored in the computer. Faults that can set the check engine light can range from a vacuum leak, engine miss-fire, low engine compression, faulty sensor such as O2 sensor or other engine sensor, hydraulic pressure loss in transmission, transmission shift solenoid, open/short in wiring harness, emission evaporative system leak, or one of over a hundred different reasons. If your vehicle has Check Engine Light now we strongly advice not to disregard it and have your vehicle diagnosed/repaired ASAP to avoid sever damaged that could be caused from failed component to rest of engine, transmission, brake system, or electrical system.

  • Brake Fluid
    Brake fluid is subjected to very high temperatures.. It must have a high boiling point to avoid vaporizing in the brake lines. This vaporization is a problem because vapors are compressible and negates hydraulic fluid transfer of braking force. Car manufacturers  require periodic fluid changes suggested replacement interval of every 2 years, to ensure reliability and safety of brake system. Once installed, moisture is being absorbed into the fluid through brake hoses and rubber seals and, eventually, the fluid will have to be replaced when the water content becomes too high. Electronic testers and test strips are commercially available to measure moisture content. The corrosion inhibitors also degrade over time.

  • Motor Oil
    Because of the real need for motor oils with unique qualities, modern Volkswagen's and Audi's vehicles demand high quality synthetic a specific oil standard of 5W-40 most engines. Motor oil must be able to flow adequately at the lowest temperature it is expected to experience in order to minimize metal to metal contact between moving parts upon starting up the engine. Rubbing of metal engine parts inevitably produces some microscopic metallic particles from the wearing of the surfaces. Such particles could circulate in the oil and grind against moving parts, causing wear. Because particles accumulate in the oil, it is typically circulated through an oil filter to remove harmful particles. Using the proper high quality lubrication oil is crucial for the life expectancy of your Engine. Due to possible of oil sludge/carbon deposits build up in engine, we suggest using only high quality synthetic oil your engine and using quality premium fuel with octane rating 91 or higher for max engine performance and efficiency.    
  • OEM Maintenance Plan
    An OEM Service Plan is a series of maintenance procedures carried out at a set time interval or after the vehicle has traveled a certain distance. This plan has been developed by Factory Engineers in the Developing stage of your vehicle. The service intervals are specified by the vehicle manufacturer in a service schedule and some cars display the due date for the next service electronically on the instrument panel. A complete service history usually adds to the resale value of a vehicle and a trouble FREE usage of your vehicle.

    We have a 91 Westfalia with a 96/97 TDI engine that decided to stop working (in a rather spectacular fashion with LOTS of smoke and noise) on our cross country trip on the I-90 near Sioux Falls. Alex
    was able to figure out what was broken (luckily only the turbocharger) and get us back on the road within a couple of days. He impressed me with his knowledge and attention to detail. I would highly
    recommend him.

  • Faith Carlson (Saturday, November 28 15 07:18 pm EST)

    Loved the service and Alex is always so friendly, honest and helpful. He does a great job. Best prices and he actually tries to make sure he get's the best prices around for repairs and never
    overcharges. Honestly best mechanic I have found to date, and would recommend him to any girl scared to walk in a repair shop alone! He is honest and takes care of you like his family - Thanks Alex!

    I traveled 800 miles with my Audi A3 TDI to get to VDUB, based on all hat I had read on the web.
    There they took good care of me and even better care of the car.
    Everything was inspected , maintained and if necessary repaired.
    And the result is a car that is good for many more miles.
    The web was right!
    Was it worth the drive?
    Absolutely, there they know what to do and to do it with the perfection Germans are known for but that can also be found in Sioux Falls.
    I can every VW or Audi TDI driver within 800 miles advice to go to this place if you're serious about maintenance or repair.

  • Mark (Monday, October 06 14 06:11 pm EDT)

    Alex knows his stuff. If he does have a question he will do the research and get back to you promptly. Always pleasant, you get to ask the mechanic your questions directly. Alex will lay out your
    options to match your budget. He is a "straight shooter". If you want to have some fun ask him what he would do next to your car. He makes good suggestions.

  • Silviya T. (Friday, August 15 14 11:32 pm EDT)

    My VW Jetta was in need of an emergency repair and Alex was most helpful! In my eyes, he just has passion for what he does. He explained everything clearly and did a great job fixing my car, along
    with some other modifications. If I lived in Sioux Falls, I'd take my VW there every time it needed to be repaired, or even just for an opinion. I've had many mechanics work on my car and I am always
    worried that they may not have the knowledge of how to work on German cars, but not Alex--he's got it!

  • Jeremiah Lindgren (Monday, June 23 14 03:24 pm EDT)

    I contacted Alex to do a Malone Tune on my brand new 2014 Passat Diesel. Alex responded to all my questions very quickly. The day I had the tune done, he was very courteous and everything was done
    very quickly. He is a great guy and very helpful. I will take my car back to him when I need more work done to it in this fashion, even though I live 8 hours away!

  • Lisa W (Sunday, March 30 14 11:31 am EDT)

    Alex is a wonderful mechanic. Trustworthy, very knowledgeable and enthusiastic. He is my first choice in all repairs on my Jetta!

  • DeLora (Friday, February 21 14 10:40 am EST)

    We took our Audi to VDUB to get a second opinion after going to the local Audi dealership. We are so glad we did! Alex did a great job diagnosing the problem at a much lower cost to us than the
    dealership. Alex also listened to our concerns and did a great job explaining the problem.

  • Kathy (Saturday, August 31 13 01:57 am EDT)

    VDUB is the BEST of the BEST. I know no one will ever match their expertise and quality of work. You won't be sorry. Thanks VDUB, I'm so glad I found you.....
