DQ250 - Servicing / Replacements & Upgrades

At the time of launch in 2003, the DQ250 became the world's first dual-clutch transmission in a series-production car, in the German-market Volkswagen Golf Mk4 R32, and shortly afterwards worldwide, in the original Audi TT 3.2 and the 2004+ New Beetle TDI. Since then the DQ250 is fitted to most 6 speed DSG models from 2003-present.

If maintained the gearboxes are very realiable and also pretty good when it comes to tuning.
Most 02E Gearboxes have a set torque limit of 360nm (265ft/lbs) in the software but this can be increased with tuning but we'll get onto that further down the blog.

We have quite a few options for the 6 Speed DSG DQ250 02E transmission, from upgrades and tuning to service parts. Please see below for options:

Service parts:

The DSG Transmissions require regular servicing to ensure perfect operation. We get many emails from customers with issues such as poor take off, jerky shifts or even faults showing on the dashboard. These are generally solved with a full oil flush and change. We recommend an Oil Change every 40k Miles or 4 years.
