D2 - oily injector harness - causes smoke?

Hi all,

Bought my 2004 a couple of months ago and the one thing that hasn't caused me any problems has been the engine, which has been as sweet as a nut....until yesterday.

Whilst driving home I suddenly found I had limited power at 2000+ revs and it almost felt like it would cut out whilst travelling up even slight inclines. Below 2000 everything seemed ok.

Anyway, I limped home and as it was dark left the car until this morning.

When I fired it up this morning it sounded rough and smoke appeared out of the exhaust for the first 15-30 seconds. The smoke cleared and the car started ticking over more normally but somehow didn't sound right (but not sure why!).

After a bit of research this morning I checked for the infamous "oil in the injector harness" issue and sure enough the ECU red plug has plenty of oil in it.

The car is back in with the dealer (non-LR) who sold it to me next week so I'm adding it to the list of issues he is already looking at for me.

My question is though whether the oil in the fuel injector harness issue would result in smoke on startup?

Sorry for the long post!

The lack of power sounds rather more like a fuel pump problem. Oil in plug usually seems to show as rough running.

some live data would be usefull to rule out the management issues... if the symptom persists after u replace the injector loom and clean the ECU unplug the AAP sensor(in the air box) ...see if it improves or not

Hi,

Thanks for the responses.

I agree entirely that live data would indeed be useful and as a new Disco owner I'm already looking at a Nanocom.

The fuel pump was changed a couple of weeks ago so I hope it's not that (it was a genuine LR part apparently).

I'll see what happens after the injector loom is changed this week and then try the AAP sensor.

Thanks for the comments - I'm loving this forum!

Just a quick update....

Apparently the fuel pump and injector harness was changed on the car and sure enough when I picked it up yesterday it was running sweet as a nut!

I haven't fired it up yet this morning, but hopefully the startup smoke will be gone to!
