Turbo Direct Injection

If you own a diesel powered Volkswagen, you are probably of the position that you “love the car, hate the dealership”. Unfortunately, dealer support for these cars is bad at best. Shoddy, expensive work, bad customer service, misdiagnosis, and lengthy stays at the dealership are far too common. We began servicing TDI’s back in 2004 and have since become South Texas’ leading TDI service facility. Since we only work on diesels, it is our passion, attention to detail, and experience that makes us the ONLY solution for your vehicle’s service needs. If you have a question regarding service, or would like to schedule an appointment, feel free to give us a call. You can also send us an email here.

B.B.B. and Angie’s List A+ Certified

BBB A+ Certified

Over the years, we have seen our share of shade-tree mechanics, hobbyists, or “internet TDI enthusiasts” come and go through the TDI scene. The problem is that these guys are not licensed, insured, typically work out of their mom’s house or other dubious locations,  and have little to no real-world experience. Because these guys are not legitimate businesses, you’re on your own when something goes wrong. We regularly have vehicles towed into the shop that have been serviced by “some guy off the internet” and the vehicle no longer runs or is having major mechanical problems and the “guy off the internet” wont return their calls. At Diesel Toys, we are licensed, insured, bonded,  and have an Angie’s list and  B.B.B. A+ rating so you can feel confident knowing your vehicle is being repaired by professionals.





We handle all of our own towing so if your vehicle is needing to be towed into the shop, give us a call. We charge $65 within 15 miles of the shop, and $85 within loop 1604. For towing outside the city limits, call for an estimate.



VAG-COM is a software package designed for the Windows™ operating system that emulates the functions of the Volkswagen dealer’s proprietary scan tools. This incredibly powerful and versatile software allows us to program keys, clear “Check Engine Lights”, diagnose trouble codes, and calibrate engine components throughout your vehicle’s electrical system. Diagnostics fees and VAG-COM fees are a flat rate of $50. This fee is waived if we perform the repair at the time of diagnosis.

**All ALH timing belt installations INCLUDE a VAG-COM diagnostics scan free of charge as it is necessary to verify the injection pump timing**

Quality Components & Warranty

Diesel Toys uses OEM or better quality GERMAN built components for all of our TDI services. This means metal impeller water pumps, Kevlar™ reinforced timing belts etc. Don’t be fooled by the cheap Chinese belt kits found all over the internet. The savings these cheap kits present are absorbed having to replace the failed components 3 months down the line on your own dime. All Diesel Toys® installed parts carry a FULL 1 YEAR parts and labor warranty that meets or exceeds the manufacturer’s warranty. All Cars after a timing belt service have a 100,000 mile change interval except early (1996-1998) TDIs. These vehicles have a 60,000 mile replacement interval and unfortunately do NOT have an upgradeable belt.

  1. Their work on the ’03 TDI exceeds my expectations. They don’t try to sell parts or services that I don’t need. The car now runs and handles great. They also managed to get more power out of it with relatively little additional cost. If you want if fixed once and fixed right call these guys.

  2. Diesel Toys is the only shop that I trust to work on my TDIs. I have owned 3 different TDIs over several years, and all 3 vehicles have been worked on exclusively by Diesel Toys since I bought them. All 3 of them are still running reliably down the road.

    The latest vehicle was very badly torn up from the dealership when I bought it. Diesel Toys was able to help me keep the costs down by accurately diagnosing the issues with this vehicle and helping me get it back on the road quickly. Their honesty and up-front evaluations have kept me from spending several thousands of dollars at the dealerships chasing problems without a good resolution.

    I would gladly recommend their services to anyone with a Volkswagen TDI.

  3. I took in my girls 02 NB TDI for some AC work. The entire system was bad. Diesel Toys replaced everything at a phenomenal price and provided awesome follow up service when we needed it. I definitely trust them with the car. They also gave me good advice on the maintenance needed to keep the car running great. Diesel Toys is the only place I recommend for tdi work.

  4. Diesel Toys is awesome! I’ve been taking my VW ’06 TDI to them since I found them. Phenomenal job every time. Diesel Toys always gives great advice. Their prices are also way better than both VW dealerships in San Antonio. Always fixed any issues I had quickly. Even had my car towed to them one day at lunch for problems and they had it fixed by the time I got off work. I will never take my tdi anywhere else. I refer all my friends if they have tdis. Thanks so much…see you soon for a tune up and some turbo boost!

  5. Diesel Toys has taken great care of my VW TDI .
    We all want a mechanic that is knowledgeable, trustworthy and honest.
    If you’re looking for a TDI guy with all those qualities… look no further –
    They’ve done my timing belt & clutch, installed new injectors & nozzles and breathed new life into my ’96 passat TDI. It drives like a beast now!

    When i was replacing my air springs on my audi and needed a particularly hard-to-find 12-point triple-head square rachet head in order to remove some bolts, i went over and they let me use their tools to get those Audi/VW-specific bolts off!

    I’ve been more than pleased with all my experiences at Diesel Toys.
    Highly recommend them!

    Diesel Toys was an exceptional experience. When someone who sells oil changes is completely willing to email you a link for needed equipment, invite you in to show you how to do it yourself, and is able to make that a pleasant experience in the middle of a very busy day it sets a precedent unparalleled by any other establishment. Honest, knowledgeable, and hard working small business owners need and deserve our patronage. I was in and out in under half an hour even with the lesson, unlike the dealership which is an all day nightmare, and now have a knowledgeable TDI mechanic’s cell phone number if I have any issues. Don’t want to write a book so I’ll stop here, but I’m seriously impressed.

    I purchased a 2006 TDI Jetta brand new from Charles Maund VW in Austin. For the first 2-3 years, the car was extremely reliable having only to do basic maintenance. Well, once I reached around 48,000 miles, the car began shutting off randomly on the highway. The car was towed to the dealership and a couple days later they called to tell me that their lead technician was stumped and could not re-create the issue. Considering the car was out of warranty, this meant that I would be repairing it on my dime so I sought “other means” to having it repaired. After an overwhelmingly negative experience with a well-known TDI guy up in Austin, I drove down from Wimberly (near San Marcos) to Diesel Toys. First things first; these guys are experts in their craft. Shop looks like something on the Discovery Channel and is extremely clean & professional. All technicians are uniformed and it was clear from the first 5 minutes of my arrival that these guys know their diesels. Shortly after dropping my car off, I got a call about three hours later to well me that they had identified the issue, fixed it, and (wait for it) it was only $100. Apparently, there was a clogged fuel line causing fuel to intermittently not reach the engine. Unfortunately, this is after I had taken the car to the so-called “tdi expert” in Austin and spending thousands of dollars on injectors, wire harness, and spending almost a month at the guy’s shop (if you can call it that). I cannot recommend Diesel Toys highly enough and intend to continue taking my car to Diesel Toys as long as I own it. I only wish I had found them sooner!
