Hi guys My TD6 has developed a whinning noise (no not the wife) It appears to come from the area of air con pump or belt tensioner. It doesn't matter if air con is on or not. It occurs when I start up car and can continue for 15 or 20 mins when driving. Then it seems to quieten. I recently replaced alternator and no noise from that side of car. both belts seem to be running OK. I am being lazy as I cant get my car into my garage and any repairs I can undertake. I have to do in my driveway. Weather not helpful. Is there anyway I can test where the noise is coming from whilst belt tensioner and air con units are still on the car. If not and I have to remove them. Is this an easy job, something I could do whilst car on axle stands.

Any advice would be welcome. Ive only had this beast for 6 months and had to replace all discs and pads, rear nearside brake caliper, alternator, drop links and lower ball joints. First thing I did was to service it and change crank case breather unit. I haven't worked on a car for 20 yrs till I bought my RR. Ive quite enjoyed it but Ive found its not the easiest car Ive worked on.

Does the sound change with engine revs ?

If it doesn't it could be the fuel burning heater running. A long shot I know, but mine sounds a bit like a jet engine and then makes a whirring noise....... 2011 Range Rover Vogue SE 4.4 TDV8

Not really. You cant hear it when you accelerate but when the engine revs die down you her it again. Sorry have read somewhere about the car having a remote heater that you can activate with the key to warm the car up but showing my ignorance. Have never intentionally used it and really don't know how to

Also do a forum search for FBH. Lots of information. Great piece of kit (providing it is working OK and your battery is up to charge ) John

It comes on automatically when started if set conditions are met. Outside temp lower than something, water temp lower than something else. Can't remember exactly. The remote fob is just an override to allow manual switch on. I can set mine to come on using Aux Heat on the screen menu. Defrosts the car and is warm inside before you go out in the morning.

It's located under the battery and the exhaust is in the front passenger wheel arch if that's where the sound comes from.....

May be a red herring...... 2011 Range Rover Vogue SE 4.4 TDV8

Thanks guys. No Ive heard that noise from battery area. It occurs in cold weather. No this is definitely from down near the aircon unit and pulleys. The more I think about it the more I think it sounds like a bearing noise.I just remember how much of a pain it was lying outside in puddles under the car replacing the alternator. If its just the air con belt tensioner that's not to bad. They don't seem expensive to buy but if its the air con pump then we are talking £250-350 then the hassle of fitting.

If it's the bearing on the aircon pump, you can just change the bearing, mine has been moaning since I got the car last February, it's a bit louder now after 12,000 miles but still works fine so wait until warmer weather and do it...

If you take the belt off and spin it you can hear it, mine sounds really rough....

I believe you can change the bearing with the pump in situ so no need to empty the gas....

It's the same pump on the diesel and petrol.... Pete

Thanks Pete. That's comforting

Hi lads just found this on search, coming home today 130 mile round trip to welshpool and back, about 5 mls from home got a loud screech from front drivers side under bonnet, thought it might be belt related so turned aircon off and it stopped. Tried again a couple of miles later and got a rumbling noise. Hope its the bearing as said above it can be sourced separately. Anyone know where from, or is it a main stealer part.
TIA. Greg.
