Hello
I have just bought a RR 2003 diesel and have been running it for about a month or so, there are a couple of small niggles but nothing of consequence (condensation in the rear lights, fan noise from centre console) but I noticed a couple of weeks ago a whirring/whooshing fan noise which rises with the engine noise, this has been intermittent but seems to be occurring more regularly now. When the fan noise starts has no pattern to it other than its more prevalent on stop start trips, the other thing is that through acceleration the noise increases up to a certain point and then recedes, this is at around 4000rpm, it appears to stop for the duration of the trip only to re-appear on restarting the engine again. The fan noise is not obvious when the engine idles it becomes audible at around 1500rpm. I don't have prior knowledge of how a Range Rover feels concerning performance but this does not seem to be impaired when the noise occurs.
Have any of you prior knowledge concerning this situation, if so any diagnostic suggestions will be welcome.

Hi,

The fan noise is just the cooling fan - sometimes when you restart the vehicle the viscous fan is still locked so the fan spins up with the engine making the whooshing noise that you have described, it normally stops within the first minute.

The fogging of the rear lights is quite common mine nomally do it if its been cleaned with a jet wash although it can randomly happen at other times.

Fogging of the rear lights can be corrected by removing the light unit and cleaning out the breathing hose on the back to allow air circulation.

hmm. I wish I knew that sooner. I drilled a few small holes in the bottom of mine and put it in the oven to get the water out.
