Puma 2.4 EGR and injector return pipes
EGR valve carbon build-up and hardened, cracked injector leak-off pipes are pattern faults on the 2.4 TDCi and can mimic far more expensive fuel pump problems.

Defender (Classic) exhaust
Exhaust and emissions parts for Land Rover diesels and petrols, including DPF and EGR components.
What is specific to the Defender (Classic)
Exhaust and emissions parts on the Defender (Classic) depend on the engine: the diesels (2.5 300Tdi turbodiesel, 2.5 Td5 five-cylinder turbodiesel, 2.4 TDCi Puma turbodiesel and 2.2 TDCi Puma turbodiesel) use emissions hardware that the petrol engines (2.8i straight-six petrol (South African derivative)) do not, and manifolds, pipes and sensors differ between them.
Have this ready when you enquire

Defender (Classic) exhaust questions
Why is my Land Rover exhaust blowing?
The usual causes are a failed gasket at the manifold or downpipe, a split flexi joint, a rusted pipe or silencer, or a loose clamp. A workshop can find the leak quickly with the vehicle on a lift.
Can I replace only part of the exhaust?
Yes. Land Rover exhausts are made in sections, so you can replace just the damaged section. Fit new gaskets, clamps and rubber mounts at the joints you disturb.
