”TDI” 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’s leading TDI service facility. Since we only work on diesels, it is our passion, attention to detail, and experience that makes Diesel Toys® 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, have no technical certifications, and have little to no real-world experience. Because these guys are not legitimate businesses, you’re on your own if 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 cared for by professionals.
VAG Diagnostics
VAG-COM is a software package designed for Windows that emulates the functions of the 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 work 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 and to calibrate injection quantity.
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 90 day 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.

Common TDI Questions
Q.Why Does My Intake Clog?
EGR
A. On all TDI engines, the EGR (Exhaust Gas Recirulation) system routes a portion of the exhaust gases through a control valve and back into the engine. This system lowers the combustion temperatures and the NOx emissions of the engine assisting in catalyzing the exhaust. All internal combustion engines have a small amount of blow-by (oil vapor) as residual oil from the compression stroke is pushed past the seals and into the valve cover area. Engine manufacturers simply route this blow-by back into the engine where it is ingested by the engine and eventually burned off. When the heat from the exhaust gas mixes with these oil vapors from the engine, it adheres to the EGR valve and the intake manifold. After 100,000 miles, this amounts to quite a bit of gunk built up inside the intake manifold. The 1999-2004 ALH TDI engines are more prone to clogging than other models. Poor mileage and excessive smoke are signs that the intake manifold needs to be cleaned. For our intake cleaning service we start by completely removing the intake manifold and EGR valve from the vehicle. We then soak the manifold in a solvent bath overnight to remove the contaminants, then media blast the internal channels to free any stubborn deposits left. Finally, we hand clean the EGR valve and reinstall both on the vehicle. If your car has over 100,00 miles, chances are your intake needs to be cleaned. Give us a call to schedule an appointment.
Q. What’s with the camshaft on my Jetta?
Camshaft
A. On the 2004-2006 PD (Pumpe-Düse) engines, the engine’s camshaft not only opens and closes the valves, but it also actuates the fuel injectors. This places the camshaft under considerable load. It is for this reason that Volkswagen has mandated the strict use of 505, 505.01, and 507 API spec engine oils. While there is some debate as to the cause, the camshafts and valve lifters have a high rate of failure. The symptoms are low power, excessive smoke, and abnormal engine noise. The “fix” is to replace the camshaft, lifters, bearings, bolts, and gaskets. Give us a call to setup an appointment to inspect your camshaft & lifters. We charge $150 for this inspection and will take about a 1 1/2 hrs to complete.
 
Q. What the %*&@# is a balance shaft?
Balance Shaft Module
A. Balance shafts are nothing new and go back decades as a method of internally-balancing the rotating mass of an engine. An over-simplified explanation of the way they work is “as the engine shakes one way, the balance shaft assembly shakes the other” and this counter-action reduces vibration. On the BHW TDI engines, the balance shaft assembly is connected to the engine’s crankshaft via chain. The issue is that the chain’s can break with little to no warning. In a perfect world, the engine would just wobble and shake once this happened as it’s method of internally balancing itself has stopped working…but. The oil pump assembly is also attached to the balance shaft assembly so when the chain breaks, the engine will lose all oil pressure and quickly lock-up through lack of lubrication. The repair is to use a gear-driven balance shaft assembly and is purchased as a kit (pictured above). This solves the issue permanently and although expensive, can save you tons of money and headaches should your chain break while driving.
