new VCU, bearings and diff mounts all ordered from Bell engineering, hopefully replacing this will solved the drive train issues and I've caught it before any damage has happened to the IRD.

I'm getting -20% on the left bank, it tends to be 10% different from the right bank on average. enough thats its flagging the Code P0172. from memory the freeze frame which triggered the code was -18% STFT and -17% LTFT

There is a voltage coming of the O2 sensors in the diagnostic unit. (all three of them) Not sure what you mean by closed loop tho? Sorry

I've got a diagnostic scanner, the engine warning light came on so plugged it in. Had a P0172 Bank 1 too rich code. We've had the oxygen sensors replaced as they weren't giving a reading at all. However the light and code still comes back. When driving I can also see that Bank 1 fuel trims are...

Thanks for your reply Is it ok to remove the VCU on a V6, read on another website that this can cause the IRD to fail even quicker?

Recently bought a freelander for my wife a few weeks ago. Lovely V6 and looked like it was in immaculate condition and drove really well. Anyway within 10 miles of driving the engine warning light came on. There began the issues of the engine running rich and can't seem to find the issue, oxygen...

Also I should add there was quite a loud hissing noise which disappeared when I revved the engine

I've given the engine a good look over, Checked the spark plugs, the injectors all sound ok and ticking away. I ran the engine with the accoustic cover off and I could hear a hissing noise but it was coming from under the manifold. All the pipes and tubes seem ok but there were some areas I...

yeah, its a mobile problem solving game o_O

I haven't actually tried, but will do in the morning. I'm actually scared to fix this simple item because it seems when ever you fix something, something else comes along

pulled over and opended the air box as the amount of rain we had was collosal. I had to pull over for 10 minutes as I couldn't see out the Windscreen. Anyway water seemed to have found it's way into the air intake even though I have a snorkel fitted. (points rearward too). The filter was sodden...

where could water get that would cause a disco TD5 to kangaroo during acceleration. Engine revs fine when in neutral but won’t accelerate smoothly. It’s happening after crossing fords or driving through puddles.

I connected it to a diagnostic reader and the fuel trims for the front bank are much higher/lower than the other bank. Would this point to injectors?

Yes that’s where the split is. It was a big split Left a whole about the size of a 2p. Here’s a better photo.

Hello, Lately my V6 has had a lack of power low down in the revs, so much so going uphill was slower than a tractor. Any way the engine warning light came on this morning with a P0172 bank 1 too rich code on the scanner. At idle it was misfiring and juddering and when driving it was like the...

Hello all. I live in the southwest. I love landrovers, specially the early 2000's one. I currently have a Disco TD5 auto kitted out for safari's etc. Snorkel, lights and Roof rack etc. We also have an 04 Freelander V6 3dr Hardtop which is our run around. I quite often go out Greelaning etc...
