BMW E38 diesel injector replacement and removal
E38 diesel does not start after replacing the injectors - what to do?
The injector correction values (adaptation values) should be reset with a diagnostic tool for the new injectors. The system is bled by keeping the ignition on for about a minute. The car should start even without the reset, but resetting is recommended.
How do you remove a seized injector on an E38 diesel?
1. Remove the injector's pressure line and connector; the intake manifold does not need to come off. 2. Spray penetrating oil at the base of the injector a few days before the job. 3. Warm up the engine and loosen the two nuts on the clamp. 4. Pull the injector up; a tight injector may need a puller or a special tool.
What torque is the diesel injector tightened to?
The injector tightening torque is 65 Nm and the fuel line's 22 Nm. Removal needs a 27 mm long socket. An injector leaking into the intake port can be serviced if the needle is not loose; the top is sealed with one or two metal sealing rings.
