My 2005 has begun making a strange noise, I think it is coming from the Turbo.

The noise rises and falls with engine RPM, it's like being followed by the cops because the sound is like a police siren.

Comments and suggestions welcome cos her indoors thinks this is going to cost a shed load of cash to fix!!!!!

Have your turbo's bearing checked by a specialist before they go out and break the whole turbo.
My dad's screwed his turbo on his TD6 and the whole change cost 3000 euros.

First check the hoses, I've not had experience on the rangie yet but on other models they can collapse so a check of the hoses is first port of call.

Next if you can get the intake hose off anf feel any lateral movement on the impellor then it sounds as though the bearings may be on their way out.

Turbo replacement will be expensive however there are other options. If you can get the Turbo off , send it to these guys. They will check it out and repair if necessary providing a quote prior to commencing work. I had them one a once over on a Classic TD Rangie a few years back. You also get some cover I think for 12 months on the repairs and some very respectable documentation on return of the turbo to go with your service history.

If you are not the type to get your hands dirty... and there are a few loitering here 8-0= then you could always get your local friendly garage to do the dirty work and send it to them. You package it up and they send a courier to collect. Normally gets a once over within 24 hours or so and telephone update on the situation.

Hope this helps. Please keep us posted on how you go on.

Thanks for the suggestions guys

My first problem is that I am in Greece for the next 18 months. I am not mechanically minded enough to check the hoses myself (I cant' even see the turbo, intercooler or hoses from under the bonnet or from under the car) nor do I have the tools here, however there is a Land Rover stealership in Thessaloniki which is around 60 miles from me, I think I will have to book it in for a look over.

Hope it works out for you ok.

I have a whistle at 1600 rom upwards now.. only time I used to get anything was when I eased off the gas I used to get a dump valve kind of sound , though not as loud as the boy racers.

The whistle I have is sufficient for me to have now grounded the RR. I will be taking my Turbo off hopefully later today weather dependant. I'll post back any observations. Then again I may once I find it take one look and trundle it down to my local indi garage... who have never done one on a l322 yet but doing some reading typically 75000 miles is about the average life expectancy and thats where my Rangie is at now.

It doesn't smoke yet but the scary though of the turbo blowing big time leaves me cold so I'd rather take the financial hit, no way the Warantee will cover it as its coated in teflon and the "wear and tear" aspect will undoubtedly kick in. :cry:

The more I read here and prod about my Rangie the more confident I am that one day I shall tame it. I have to say this far just over 2 and a half years in to owning my 2003 I have been very lucky to date.

This seems to be a widely unreported problem. I cant seem to find much info on causes, repair costs etc in fact my local independent Land Rover repair shop in the UK has NEVER replaced a L322 turbo (they have been in business for over 30 years) they have however replaced split, collapsed, and de-laminated hoses.

Anyway a Land Rover dealership here in Greece will try to diagnose my problem next Tuesday so I will report back then.

Well, I may need to eat my words about getting my hands dirty! I took a look... look being the key word.

To get to get to the Turbo which those clever chaps at BMW have cunningly wrapped a whole car around you need , it appears, to remove the injectors, inlet manifold and air box with all the associated attachments.

I was foiled by some strange screws on a unit on the end of the airbox. And to be honest once I then retired and read up about the process on a BMW forum where the reality dawned, Once I had dried off I went back out and put back together the items my expploration had required the removal of.

I couldn't get to see the hoses. I was working on the driveway so access to the underside was not possible.

I've worked out that having one failed injector last year I will be getting these reconditions when it gets run in on the 12th April.
Lets hope it is a hose! If not I can get the Turbo reconditioned if repairable £400 (Plus VAT), or replaced £700 (plus VAT) Injectors reconditioned for £120 x5 (one is new, at the most plus VAT) and the labour guessed at £250 at around £48 an hour plus the VAT. So around £1500 worth of work all told.

A new genuine Turbo is nocking out at £1400 plus VAT on a quick internet trawl, which is a Garratt Turbo with a Landrover Oval stamped on it inflating the price by £700!!! :shock:

:pray: PLEASE BE A HOSE! :pray:

Is it a standard BMW turbo or has it been modified by LR?

Honest answer.. I don't know if they were tweaked but I doubt it.

Seems to be a BMW part number reference here;
Range Rover Td6 2002-05 2.9L D M57D GT2256V VNT G 712541-0001/2/3 7785839F BMW A

from this PDF from the chaps who will hopefully sort it should it need fettling.

Thank you that was very useful! I have a whining noise between 800-1600RPM that sometimes stays all day and sometimes disappears for a week. I cannot find any pattern but I'm afraid it's the turbo although there's no decrease in performance yet. I think BMW turbos should be available easier and cheaper if it needs replacing...

I spoke to a chap from a turbo reconditioning company and he believes the whining noise is from a gasket or hose, not from the turbo itself. My turn to try and look around…

Repaired. Pictures Added.

Hi

I got my vehicle back today after being in the Land Rover repair shop here in Greece for over a week.

They took their time trying to diagnose where the noise was coming from and eventually decided I had a faulty Turbocharger.

I was at first quoted 3000 Euros for the Turbocharger + labour which was then reduced to 2200 Euros + labour if they purchased it through an independent dealer (not through Land Rover parts).

I telephoned Honeywell / Garrett in the UK and they gave me details of a Garrett supplier in Greece. I paid 1100 Euros for the Turbocharger including delivery and 630 Euros to the repair shop for labour plus fitting a new air filter and Turbocharger air system filter making a total repair cost of 1730 Euros.

They were unsure of the actual fault within the Turbocharger itself but the noise has now disappeared so the Turbocharger must have been the source. I have attached some photos.

The exhaust side of the turbo casing


Inside


Closer


I can feel side to side movement along the X-Y (side to side) and A-b (front to back) axis. The installation manual says ' It is normal to feel some up and down movement on the wheels' I assume the 'wheels' are the impellers and the OK movement is along the A-B (front to back) axis. This side to side movement can be felt on both of the impellers. I'm not sure that I should be able to feel movement across the X-Y axis this may indicate a faulty bearing.



Compressor Side



Inside



Side to side movement can also be felt on this impeller



Lubrication area to the bearing


Other Parts


When I return to the UK I intend to have the faulty Turbocharger re-conditioned to keep as a spare if the need should ever arise. I hope the re-conditioners can shed more light on the fault. It has been an expensive problem to fix but with a little work I managed to reduce the repair cost to a bearable amount.......just.

If anyone has any thoughts or feedback or needs any more information I will be happy to help.

They are fairly simple units with little to go wrong except bearings from poor lubrication. Is there a chance the unit has suffered poor oil circulation?

The turbine fins look worn in one of the pictures... :think:

So I believe I have the same issue. History of the issue below:

1. Accelerating away from the lights on the way home from about 50 miles of driving led to a large puff of smoke coming out of the back of my Range Rover FF. Acceleration was impaired completely and anything that used to engage the turbo led to a large plume of black smoke coming out of the back;
2. From research it was Turbo related so I booked it into my local diesel expert close to Harlow;
3. They found it to be the pipe from my intercooler and turbo had split and thus replaced it;
4. Driving off from the garage after it had been fixed and at a round-a-bout that same thing happened. Given I'd just picked the car up, they thankfully picked up my car from my home and took a look again. This time the problem was because the other pipe had come off, mainly because they hadn't put it on properly. According to the garage the hoses are a pain to get on/off, hence the problem;
5. So after the car was dropped off at home and the owner of the garage drove it home, I was hoping all was ok. Unfortunately not;
6. So no black smoke, apart from maybe the first drive of the day. But it was replaced with a high pitch whine at approx 30 MPH and mainly when I took my foot off the accelerator, rather than accelerate;
7. After about 1,000 miles I get the noise when I accelerate and take my foot of the accelerator. The noise also starts at about 20 MPH and in the 1,800 - 3,000 RPM range;
8. My car has done just over 100,000 miles now.

So my gut feeling is that the jubilee clips are lose on either of the pipes connecting the turbo, or that the turbo has gone. What makes me think it is a hose, rather than the turbo itself is that I didn't hear any noise until my hose went and I got it replaced. My car is in for its yearly service in a week and I've asked them to have a look when they're under the hood, so I will let you know how it goes. But does any one else have any experience of this type of scenario?

Thanks,

Matt.

Hi matt

I have same symptoms as you have listed, sounds like someone blowing on the top of a bottle only when engine is warm and only above 1800 revs. What was the final outcome from your scenario

Hi there,

Sorry for slow response but I've been away on holiday for the past two weeks. So, the problem I had was loose jubilee clips after the company replaced the hose. They are apparently a nightmare to get on. So that solved that issue. First port of call is to check your hoses, maybe loose, a small hole, or something else. An accomplished garage should be able to do it pretty quickly and cheaply.

Since then I've started to get a whine when the turbo disengages, but apparently at 110,000 miles it is pretty normal. I would expect in the next year to have to replace my turbo, but found a great service place close to Roydon that can source them pretty cheaply.

Let me know how you get on.

Matt.
