Design change to R2S turbochargers VW T6, T6.1
Design change to R2S turbochargers VW T6 / T6.1
In vehicles equipped with 2.0 TDI engines used in the VW T6/T6.1, a design change has been introduced to the EGR branch in the exhaust manifold (see Fig. 1). The older version of the turbocharger has been discontinued – only the new version of the R2S turbocharger is currently available.
If the new version of the turbocharger is installed in a vehicle where the older version was previously fitted, additional mounting components are required. These components are not included with the turbocharger and must be ordered separately.
Fig. 1. Comparison of system versions (old / new) – the difference in the EGR branch area is marked with a circle.

Recommendations
- Verify the vehicle variant (model and gearbox) before installation.
- Treat part numbers as reference only – we recommend confirming the correct selection by VIN.
- Mounting components must be ordered separately (OE / parts supplier) – they are not included in the turbocharger kit
