I might just temporarily wrap it in aluminium foil tape or something see if the noise still occurs

Could it be the exhaust flexi hose section at all there is quite a bit of sooting on that to be honest and the mesh is breaking down

Noticed until its not at temperature it doesn’t do it when its at temp the noise happens if this narrows it down?

Its very noticeable in the first video. If you are listening through a mono device that could be why it might not be heard? The screechy whistling sound starts about 3 seconds in then again at 12 seconds in. Second video plays fine for me though can anyone else confirm?

The first noise you hear on the video started a while ago, maybe back in May or June, but it goes away so quickly I never thought it to be an issue tbh thats more like a wooshing sound, but yesterday that high pitch noise (almost sounds a bit like speaker electrical buzz occurred) Only under...

Does anyone know the pin out what controls the Diff lock light on engine loom in the master socket on bulkhead Had to swap my engine loom got all the other connectors going all spot on other than the Diff lock light. We suspect possibly one of the pins are maybe wrong in the new dash bulkhead...

Its the redundant EGR system all the electrical gubbings are still present though so something either failed or overheated in that. The EGR was blanked off but all the control systems are still present. I am going to strip it out

Good morning So after the old EGR wire coming off the third point of the alternator fully melted through my old engine loom I have had to order a new one, it still works fine the loom, but I am worried that long term it has compromised the integrity of it On my model it came with a factory...

Its the same through the entire loom so far

I don’t know what proper burned is, but hopefully this photo helps its closer The smaller wire on the lower terminal has shed its out pvc skin completely through the loom as I have pulled it through. Managed to get it up to the Thermostat elbow atm will continue pulling it through if i can. It...

So still struggling to work out what that connector actually is. The further connector down on the alternator which melted seems that it could be several things and I am a bit confused. one post said it could be the battery warning charge light. Now that the wire has been pulled the battery...

Now I have it at home the wire which has melted appears to be for the ignition I think. The other two although a bit scorched definitely aren't the source of the issue that is ignition then Well its the lowest connection point to the alternator anyway

You think unlikely anything to do with the head gasket change? I was wondering if it was a bad earth or something

I don’t think any defender engine loom is fused not specific to my vehicle.

Apparently the loom isn’t fused? For the engine? But i don’t know enough about the wiring setup on defender

The whole loom has gone right around the engine all the plastic covering has popped open and all wires are exposed. That portion touching manifold was from an old kenlow system i think thats long since been removed. I just moved it for the purpose of photo

Just been in Scotland and last night my engine loom melted. Managed to get to Gretna and decided it wasn’t worth the risk so got it recovered home. The engine loom has completely melted and I am not sure why. We have done heat gasket last weekend so wondering if some wires got disturbed...

1999 300 tdi 90 CSW Ill take my door card off and have another look Can confirm my wiper and heated rear window all work fine though

My defender had its roof off to repaint a few weeks back. Since getting it back noticed the centre rear break light isn’t working. I have tested the fitting itself with a voltage tester with breaks engaged and the wires and bulb holder are both dead unfortunately, no volts When i was putting...

The leak off pipes Thanks for this I wasn’t really sure it would be that issue as they were only replaced in August last year, but sure enough the 2nd one in from the back of the engine is absolutely soaked in Diesel.
