Hello.
Having managed to get my IID BT going properly now, I've done a read of fault codes, some of which I've seen before and some I haven't. IPC-Instrument Pack U0100-87 (20) Unknown U3000-46 (40) Unknown PCM-Engine Puma 2.4 P0480-23 (2F) Fan 1 control circuit - General signal failure - signal stays low P1103-00 (6C) Mass air flow sensor in range but higher than expected P0234-00 (68) Turbo/supercharger overboost condition Previously, I've had P1103 and cause the MIL to light; and on a separate occasion it's gone in to limp mode (cleared after a restart) with P0234 showing. I think P1103 came after I'd been driving for 5 hours, stopped for a couple of hours then had another hour of driving. I say I think because I hadn't looked for codes before. P0234 came after driving for about an hour on the way home from the LRO show. When I was sitting earlier that day idling for 5-10 minutes the engine revs occasionally went up from 750 to 1100RPM for a few seconds which was a bit random. That happened about 3-4 times. MAF issues and overboost sound like they could be related? I've no idea what the first three (U0100, U3000 and P0480) are, any ideas? Other things that may be relevant: 17k miles, recent service (oil and filters), always starts on the button but over winter I get white smoke starting at about 30s and lasting 5 minutes, glow plug lights always come on, even when the engine is hot, engine will quite happily start from stone cold even if you don't use the glow plugs. Once the engine is warm, if you're accelerating or it's under load it sounds sweet as anything. At partial load (like cruising at 60) it rattles. It usually just idles quite happily. Edit: I don't have AC. Could MAF sensor issues be causing my problems? What about the other codes? Thanks in advance  |

Yes seen them all
I am currently at work so don't have access to my desktop to show you P0480 but the below link explains the U dtc,s http://www.defender2.net/forum/topic23232.html?highlight=dtc |

For future reference, your posts on this thread are quite helpful:
http://www.defender2.net/forum/topic5443.html Regarding this thread: http://www.defender2.net/forum/topic5125.html I'm quite happily getting about 360-80 miles before the low fuel light comes on, and it sounds miles better with Shell go faster diesel than normal diesel. The consistent theme is most threads on subjects like this are BAS, Lorryman and Caterham 
Edit: oh, and the EGR makes the noise I'd expect when I turn the engine off. |

Are you talking about the turbo overboost condition?
I had the same and it was just a broken wire within the connector of the actuator from the turbocharger. Not visible from the outside, but a gentle pull on each of the wires made it clear, that one was faulty. It normaly works fine until you run over a bump and the cable loses its connection. Then the actuator will stuck in its position and the van geometry is still open. There is a repair loom available for fixing this. After fixing the 1103 was gone as well. I get some IPC faults, when I read the codes with ignition on, but without the engine running. Regards, Max |

Thanks Max I'll take a look at that tomorrow and see if thats what it is. Were you also getting the fan 1 fault as well?

Canβt remember. I tend to say it is a problem, when the codes are checked while the engine is turned off. Anyway, this is nothing in the air intake area, therefore it is a different problem. Maybe it is just the relay or its connectors. If this code still remains while engine is running you should simply check the circuit with a multimeter starting at the fuse and end at the mass connection.

Good day MMR1988. You mentioned that there is a repair loom available for the turbo actuator. I noticed recently broken insulation on one of the wires going to the actuator connector. Can you let me know where I can get the repair loom with connector and the PN?
Thanks. |

Thanks Martin! By the way, I did get in the MAF connector that you sent me and I installed it. Pity I didn't notice at the time the cracked wire insulation at the turbo connector otherwise I would have ordered that too. Will eventually get around to ordering it. Not much room though in that harness to do the splice. LR currently in garage for an intermittent power loss problem. EGR valve and MAF Sensor already replaced. Mechanic suspects a turbocharger control issue. Will wait to see how that pans out. Never ending problems with the not-so-old girl but I love her!
Cheers. |

Click image to enlarge Click image to enlarge Since my last post 24th Nov 2020, much has happened with regard to my power loss issue. The ENG light would illuminate on every drive, always after a couple of kilometers, and when cruising on flat straight roads (i.e. with no excess power demand). The engine would reset after every re-start. After much deliberation, testing, and consultation with Land Rover, my mechanic advised that my turbo needed changing...ouch! So we did that and all worked well on the test drive, no power loss. BUT, on getting back to the garage he heard an air leak noise. Found the intercooler had split along the side! More $$$$$!! My gut feeling is that the power loss was originally due to the split in the intercooler and that the new turbo outperformed the old one thus compensating for the air loss, and so the system appeared to perform normally. It's also possible that the new turbo made the split worse which explains why no air leak was heard before. As if that was all, when removing the AC condenser to get access to the intercooler, the condenser brackets were found to be badly corroded. Fortunately the fix was relatively simply. New brackets were manufactured locally and fitted. Here are a couple of photos. And no, I haven't been driving through salt water. Just another poorly manufactured unit! So, in conclusion, I believe that my old turbo may be serviceable. Guess I'll clean it up and keep it as a spare! |
