It’s vital to keep injectors in good nick to prevent fuel supply problems. Bad fuel injectors on a Landrover can lead to engine damage or even catastrophic engine failure.

Patagonia. Nov 27, 2010. #1. Back in July my Disco Td5 started misfiring & cutting out, not in the classic oil in loom way, but rather massively. Nanocom would show a scramble of the following fault codes: FAULT 27-01 injector 1 peak charge long (CURRENT) FAULT 27-02 injector 2 peak charge long (CURRENT) FAULT 27-03 injector 3 peak charge long
Posting Permissions. At 76000km on the clock our 2006 Discovery 3 TDV6 started driving with a erratic 'shudder' This was diagnosed by LR as the injectors needing replacing. Without going into the dialogue I had with LR who compromised by replacing the fuel filter we still have the problem (now 86k). Anyone out there who can recommend someone in

Next, pressurize the fuel system, turn key off and crimp supply hose off, watch pressure. If pressure falls off quickly, remove clamp, pressurize, shut key off, clamp return line. If pressure falls quickly with supply crimped, presumption is that injectors or pressure regulator are leaking.
The way I checked was to take out rear mat, undo the plate, undo the two fuel pipes, careful to replace them the correct way round again, one is in and one is out. Then took a screw driver and hammer to the big round cap that holds the top on. Take out the fuel pump and poor the expensive stuff back in the tank.

Who suggests to exceed the 1 turn is a bit paranoic IMO, the 1 full turn is already at the safety higher limit cos other almost similar PD engines (VW) have 1/2 turn (180 degree) adjustment exceeding the 1
Discovery 3 tdv6 Excessive Smoking. Hi Guys. I recently purchased my Discovery 3 and previously injectors were renewed. Now the Vehicle smokes excessively on idle and theres abit diesel smell in the smoke. I did the decat and Egr blank off and the smoke has gotten worse now. Please help as im running out of ideas as even injectors were tested
1) Stick a vacuum gauge in the front port. 2) Remove a spark plug and screw in a compression gauge. 3) Take the wire and connect a spark tester. 4) Unplug a Injector and stick on a noid light. 5) Have assistant crank while I watch and record results. No spark or noid light..Sure, thats a crank sensor or the wiring. MEMBER. 2001 LAND ROVER DISCOVERY 2. V8. 4WD. AUTOMATIC. 16,100 MILES. When accelerating car stutters till you stop accelerating, then it runs smooth as long as you remain at a constant speed, seems to be getting worse in the last couple of weeks. Have not had a tune up this year, wondering if that could be it or could it be a dirty air filter

Here you can see how I removed the injectors from my LR Defender 200 tdi. Cleaning, seeking for any leaks, changing the nozzles and testing all the injector

Open Circuit fault code reading for cylinder one. Faults cleared and returned when misfiring again. Decided that based on the evidence above, it was most probably a faulty injector. expert help advised that "failing when warm" is a common way for TD5 injectors to go.
As the 'code' will need updating to compensate for the wear that has already occurred on it. Fuel through injectors should be 38-42degC. He doesn't endorse blanking EGR's, as it alters the air flow characteristics through the engine, and the ECU has to compensate away from OEM. They also aid the heating of the engine.
