I still can't see the other connector but will have a look at mine to see what is down there. Mine's a V8 though. Can you get a better still pic at all?

I'll post some pics of the sensors and connections etc I mentioned earlier.

I just went round to visit one of the member near here - Modelsp - who was amazingly helpful. He helped to isolate the engine noise to the main tensioner pulley so I'll order one of those tomorrow.

As for the ABS sensors, it looks like they were replaced at point and most likely didn't have the correct female plugs at the end. What the last person did was cut the wires close to the ECU and joined the wires from the new sensors there. However, he left the wires really long which could be throwing a fault due to the increased resistence. I'll try have a go at joining the wires the way they should be and see if this clears the fault. Any idea why the last person/mechanic did this?

The Nanocom also pulled up an O2 sensor issue, so will change those too. On the way back the speedo wasn't working and the hangbrake exlamation point came up, so not sure if we knocked a plug while looking at the ABS. Recon it might be best to go back to horse and cart.

Ha! I just went out to Bunnings to buy a multimeter to test the ABS sensors before I went cutting and connecting cables. However, I plugged the harness back in so I could get the speedo back and the three amigos went away.

All of that and I believe the issue may have just been due to the harness being a little loose. Hopefully that's it, but thanks for the help as I've learnt a lot more about the Discovery now.

They'll be back.

Yeah, I don't doubt it. For the moment perhaps that was the issue since the last owner said they just came on. If it was a loose plug then that sounds reasonable.

The extra cable shouldn't effect the ABS signal, I thinks the replacement sensors had a long cable that should have been fed right back to the SLABS ECU rather than connecting into the harness randomly.

Just received a new tensioner and pulley from Karcraft today. Unfortunately after installing it the annoying whine was still present. Think I might resign and take it to a mechanic as I'm not sure what the issue is.

Turns out it's the alternator that's making a noise, and there is also too much movement in the pulley near the AC. Total for a rebuild and new pulley is $480 including labor. Recon this is reasonable?

Is he only putting bearings in the alternator? If so I would purchase a complete unit new. Not to hard to fit.
