Removing the EGR radiator
Drain the coolant. Remove the particulate filter. Remove the left upper coolant pipe. Remove the coolant pipe from the top right. Remove the oil filter housing. Loosen clamp -arrow- and remove exhaust gas recirculation pipe -1-
Unscrew bolt -1- and banjo bolt -3- and place oil supply line to one side. -Pos. 2- do not take into account.
Unscrew bolts -1 - and -2-, remove the exhaust gas recirculation system pipe.
Remove plug connector -2- from bracket (orange) exhaust gas recirculation temperature sensor -G98- from the bracket and disconnect the connector. -Pos. 1- do not take into account.
Unscrew banjo bolt -1- and bolt -2- and place coolant line to one side.
Disconnect el. connector -1-. Carefully press linkage -2- away from ball joint -arrow-. Unscrew bolts -3- and remove intake manifold flap motor 2 -V275- -item. 4-. Repeat the entire process of performing work on the other side of the vehicle.
Remove vacuum hose -1 -. Remove the coolant hose by unclamping the retaining clip -2-. Remove the coolant hose by loosening the hose clamp -3-. Unscrew the bolts -arrows- and remove the exhaust gas recirculation radiator from the cylinder block towards the top
Installation
Install in reverse order. Replace gaskets and seals. rings. Secure all hose connections with hose clamps of the appropriate series. Install the intake manifold flap drive motors. Install the coolant line. Install the oil filter housing. Install the coolant pipe on the top right. Install the left upper coolant pipe. Install the particulate filter. Fill with coolant.
