Discovery 3 Engine Start Issue, Error P062D-0 Detected

Click image to enlarge



Hello dear forum community,

I turn to you with the hope that someone among you might have had similar experiences and can assist me. I own a Land Rover Discovery 3 from the year 2007, powered by a 2.7-liter diesel engine, which is currently facing some difficulties. Specifically, the engine refuses to start. It does attempt to start (the starter is working and the engine shows signs of life), however, it does not fire up.

As the starting issues gradually emerged, I used my old diagnostic tool to read the error codes. The codes displayed were P02A1 (Cylinder 2 – Balance Injector Leaky), P020C (Injection Duration/Timing Cyl. 2 – Deviation from Target Value), and P020D (Injection Duration/Timing Cyl. 4 - Deviation from Target Value). I cleared these errors subsequently.

To better understand the current problem, I acquired the IID Tool and read the error memory again. Now, the diagnostic tool only shows the error code P062D-01 (25) – (Fuel Injector Circuit Performance - Bank 1 - General Failure Information - General Electrical Failure). My research indicates that this error code could signify various issues, such as an open or short-circuited wiring, a connector in the injector control circuit of bank 1, a faulty fuel injector, a defective PCM or EFI controller, or a programming error of the controller.

Some time ago, I encountered the problem that the engine poorly started or did not start at all in cold condition. If it did not start, I had to wait about 24 hours to try again. When the engine finally started and ran, it ran very unevenly for the first 10 to 20 minutes, which seemed to me as if it was not running on all cylinders. I had to give more throttle to prevent the engine from stalling.

After about 20 minutes, however, the engine ran smoothly and seemingly on all cylinders. In warm condition, I could turn off the engine for about 3 to 4 hours and it would start again without issues as long as it was still warm, although I noticed that initially it smoked a bit more until it reached its operating temperature.

As a first step, I replaced the diesel filter, which however did not resolve the issue.

Next, I wanted to replace the glow plugs, but they could not be removed and threatened to break. Since I had already read the error codes P02A1, P020C, and P020D with another diagnostic tool, I decided to examine the injectors more closely.

I removed all injectors, marked them beforehand to know where they belong, and then looked into each combustion chamber with a small inspection camera to find out which glow plug was defective. I discovered that the glow plug in combustion chamber "5" was defective and replaced it with a new one.

Subsequently, I cleaned all injectors from the outside, inserted new seals, and remounted the injectors as well as bled the diesel lines.

Lastly, I purchased a new starter battery and installed it. Naturally, I disconnected the battery during all works.

Since the work on the injectors and the glow plug, the engine refuses to start and the new error code 062D-01 (25) – (Fuel Injector Circuit Performance - Bank 1 - General Failure Information - General Electrical Failure) is displayed, no further errors are shown since the engine does not start.

I would like to add that about 3000 km ago, the following works were carried out in a workshop: oil pump, timing belt set, timing chain set, and camshaft repair. Unfortunately, this workshop no longer exists, so I cannot inquire there.

I do have a few questions:

1. Can I retrieve live data with the IID Tool during the starting attempt to better narrow down the problem?

2. Is it possible to program new injectors with the IID Tool? If yes, is there anyone here who has done this before and could give me some tips?

3. Has anyone had experiences with this specific error code and could provide me instructions on how best to proceed to overcome the difficulties?

4. Could the indicated error code be related to the previous repairs?

5. Are there specific parts that could cause problems more frequently in my situation, which I should check or replace?

I appreciate any support and advice greatly.

Many thanks in advance!

Warm regards

DiscoveryDriver

P.S.: It would be great if someone has experience with the IID Tool and could provide me with some insights or tips regarding this.

Starting Issues on 2007 Land Rover Discovery 3 (2.7L Diesel)

Hello everyone, I own a 2007 Land Rover Discovery 3 with a 2.7L diesel engine facing starting issues. The engine tries to start but fails. Previous diagnostics displayed error codes P02A1, P020C, and P020D, which I cleared. Now, my IID Tool shows error code P062D-01 (25). I used to have cold start problems; the engine ran rough but normalized after 20 minutes. Changing the filter didn't help. Has anyone had similar experiences? Thanks in advance, DiscoveryDriver

I think you need to get the air out if the system.

I appreciate your suggestion to remove the air from the system. Could you possibly provide more details on how I can do this best? Is this a process I can carry out myself or would it be better to consult a professional?

First research that fault code or tell us what it is

The fuel is at very high pressure so I shouldn’t tell you.
But as long as you stand well away from the engine you could loosen the metal pipe to one injector at the front.
Loosen it approx 2 turns

Loosen:
Front left side
Front right side of engine.

Crank the engine over and then check to see if fuel has come out.
If fuel comes out. Tighten them up.
Try starting again.

I have bled the fuel lines directly at the injectors. Enough diesel came out, so I think it should be bled now. Best regards
