Front Section - Bi-Turbocharger Vehicles

WARNING: This page is about a different car, the 2018 Land Rover Range Rover, 2017 Land Rover Range Rover, and 2016 Land Rover Range Rover. However, it is still accessible from the selected car via links, so may be relevant.

The front section comprises of two catalytic converters or, if a DPF is fitted, one catalytic converter and diesel particulate filter. The bank 2 inlet pipe connects to the catalytic converter and bank 1 inlet pipe will connect to a half shell that is located between the two catalytic converters or catalytic converter and diesel particulate filter (if DPF fitted).

On vehicles with SCR System fitted, an additional SCR catalytic converter is located in the front section after the DPF.

Each inlet pipe is fitted with a flange that connects to the turbocharger for each cylinder bank. The bank 2 inlet flange uses a 3 bolt fixing and the bank 1 inlet flange uses a 2 bolt fixing that are screwed into threaded holes in each of the turbochargers. Each flange is sealed using a gasket and both inlet pipes are fitted with flexible couplings.

The catalytic converters or DPF (if fitted) have an outlet pipe that is secured by a clamp to the center section. The outlet pipe has 2 mass dampers which will absorb resonance from the system. The outlet pipe also has one hanger bracket which is welded to the pipe.
