The HPA programming for the DSG started in RGT projects for the 2005 SEMA show and was originally developed as a support product to allow the R32 DSG to handle the demands of 400-plus-horsepower turbo conversions. Lucky for us HPA didn't just focus on the R32, but expanded the programming to encompass all DSG transmissions. Our results on the 2.0T FSI engine were better than expected; in addition to increased power, we saw a reduction in black smoke and a decrease in timing retard under wide-open throttle.
Having owned numerous DSG-equipped vehicles, I had to wonder if the HPA DSG software upgrade would have any ill effects. After much research, it is my conclusion that it's not the DSG software or extra power that reduces longevity. It's improper maintenance of the DSG transmission.
VW and Audi recommend servicing the DSG/S-tronic transmission every 40,000 miles. Manufacturer-recommended service intervals reflect the maximum mileage that you would want to accrue before potentially detrimental effects occur. Also, their mileage quotes may be biased and serve to fit the free-service intervals rather than ensuring the extended life of the vehicle. So what should the service interval be? As always, there's no clear-cut answer that fits every vehicle. The life expectancy of the DSG's synthetic fluid is dependent on the varying range of temperatures, pressures, topographical variances, and driving styles that it is exposed to.
For example, take two DSG-equipped cars driven in a mild Southern California climate. One vehicle is unmodified and driven conservatively, so the recommended service interval of 40,000 miles should not be an issue. The other vehicle is heavily modded and driven aggressively on and off the track. In this case, the DSG service interval should be more frequent, about every 20,000 miles. Think of changing the tranny fluid like you would your engine oil: doing it often and with the proper tools can save you a major headache.
If you plan on keeping the vehicle for any length of time, it could be worthwhile to invest in the tools needed to perform service yourself. Most of the initial expense is invested in tools, but the rest comes from the oil filling adapter and software. It is possible to "MacGyver" a fill tool, but the money you save by doing the job yourself will eventually pay for the OEM tool. As for the software, it is used to make sure the fluid level is correct when the transmission fluid is up to temperature. This step is required, because if the fluid levels are incorrect it could be disastrous.
