Restricted performance

[WhiteD3]

Hi all.

Recently my MY18 SD4 HSE has been playing up. At random times it loses 95% of the throttle response and the engine is noticeably noisier (like an old tech diesel). It can happen from a standing start or while driving. From a standing start with my foot flat to the floor, it creeps away and can take say 10-15 seconds to hit 10 kph and then slowly accelerates after that; holds gears too long, noisy. Comes and goes.

I had it in for a "diagnostic" last week with the result being NFF.

This morning after a run down the M1 and back it went into "restricted performance" mode which then cleared, and then occurred again. Luckily we were back in our street again. During "restricted performance" mode the car performed as previous described. LR roadside assist say it has to be towed to a dealer.

Any ideas?

Cheers,

Mark

So......after a week at the dealer the fault was diagnosed as "Checked vacuum hoses and found vacuum hose from solenoid to variable vane turbo actuator hose had come adrift partially and is allowing vacuum pressure to be lost. Refit vacuum hose properly and cleared all fault."

Picked it up this morning and the same issue occurred from start up. Didn't get out of the driveway. No service Dept on a Sat morning so I was left with the sales manager who was suitably mortified. So back to the Golf (the car, not the game) for some more very cramped motoring.

Not happy Jan.

Hope You didn't pay to have the fault diagnosed. Cos they obviously didn't.

[WhiteD3]

Since the last update the D5 is still in the shop. Thus far it was the air filter, then the fuel filter, then a collection of hoses and now apparently it's the secondary (?) turbo. That part is coming from the UK so 3 weeks with no car and no doubt quite a few more to come.

Sorry to hear that, fingers crossed they are getting to the bottom of it now. Shouldn't you get a loan car as yours is still under warranty?

Ron,

Originally I was offered a loan car for 5 days which I didn't take as I had access to another car and didn't want the hassle of picking up the loaner only to have to take it back a day later when the D5 was fixed. I have now asked for a long term loaner which is doable but LRA have to approve it as it comes from (I think) a third party.

Hate to be the bearer of bad news, but that’s what mine did result engine replaced (long engine). Happened when travelling at Christmas time went into restricted performance twice, towed to dealer had car for over a week the result NFF. After returned still had restricted performance alerts and what I call going into “ Perkins diesel mode “ taken to local dealer and after some investigation they found excessive blowby and Land Rover said to install a new long motor. COVID hit just after I got the car back so I have not been able to do many Kms but cars is performing normally.
I didn’t get a real explanation of what went wrong (which was disappointing), I don’t think the dealer pulled down the motor but may have been returned to Land Rover to check out.
Another interesting thing that occurred at the same time was a fuel stain around the fuel filler which I think came from vent near filler. I not sure of the connection, maybe the tank was pressurised somehow, it hasn’t happened since and wasn’t happening before.
The car has done 40,000 Kms.

Symptoms I gave to Land Rover
A number of restricted performance alerts.
Increased turbo lag
Goes into “ Perkins diesel mode “ high induction noise and sound like old indirect injection diesel tractor. Usually occurs when stopped at intersection or slowing down in traffic , clears with restart.
Sometimes when 1st started stalls when put into gear.

[WhiteD3]

RW,

I mean this in the nicest possible way but......................I hate you!

What you've described is exactly what I've encountered. I haven't had the pleasure of driving a Perkins powered anything and now I don't want to.

Was yours the SD4?

I have interrogated the dealer today who assure me (not that I'm assured) that it is in fact a turbo although I'm not sure which one. 4 weeks transit from the UK which is optimistic I think given the deliveries I'm getting out of the US and EU at the mo for work purchases.

To be as fair as I can be, this is the first time I've had a Disco off the road since I started driving the D3 in 2007 so I suppose I've had a good run.

I'm stilled ****ed off though.

It’s the same as yours 2018 HSE SD4, strangely mines still has original turbo etc. Anyhow good luck with yours.

[WhiteD3]

So....7 weeks in and the D5 is still in the shop. Turbo replaced but there are apparantely, "responsiveness gremlins" ongoing.

I quite like the Disco sport loaner but I want my bloody car back!

[WhiteD3]

"Responsiveness gremlins" has now translated into low compression or some such I'm advised. Now we have a new engine on order. 4 to 5 weeks away which will mean 3 months off the road for the D5. ****ed off am I!

[IndusD4]

Sorry to hear that, they could at least give you a D5 loaner instead of a Sport. Or even a Defender.

Ron

[WhiteD3]

A sorry saga this has turned out to be.

Last week JLR coughed up (unsolicited from me) the lease repayments for 3 months which I thought was good customer service and PR.

Got the D5 back on Wednesday complete with a new engine, all fixed, test driven multiple times, etc. Lasted < 24 hours and the same fault occurred. Zero power, stalling, restricted performance, back on the tilt tray to the dealer. I would post the video of the car in fault that I took at the time but its not fit for public viewing. I did send it to JLR and the dealer who did the work as a way of "expressing" my disappointment.

Now waiting on another loaner to arrive today.

Not happy.

[Lukeis]

I’m reading this in horror.

at which point do you simply hand back the keys?

Gee that was good of them.

But as for the rest of the saga, very annoying,i won't comment further, but I bet you can guess my thoughts.[bigsad]

[WhiteD3]

..............at which point do you simply hand back the keys?

That's where my mind is at right now. QLD does have lemon laws although I'm reluctant to go down that road just yet. Interested though, to know anyone's informed opinion on the matter but please don't post anything here that could be detrimental to the cause.

Maybe drop keys off and drive off in a new defender.

[WhiteD3]

Maybe drop keys off and drive off in a new defender.

If, and that's a big if depending on the outcome of this current drama, a Defender is in my future it'll be a MkII to avoid the bleeding edge of technology.

I have no experience of lemon laws but you’ll do well to understand consumer rights. See this link Car Lemon Laws in Australia - Are You Protected? | Canstar (https://www.canstar.com.au/car-insurance/lemon-laws/)

or for a more entertaining way, watch this link

Consumer Guarantees Revisited - YouTube (https://youtu.be/OCW6NuLEMNA)

its your right, they are not doing you a favour

[WhiteD3]

The prognosis now is the intake manifold which was not part of the new engine. Ex stock Australia so hopefully this is it and we can get back on the road.

[scarry]

So looking at the date on your first post, thats 3 months so far with the no vehicle, and its still ongoing[bigsad]
I feel your pain.

[WhiteD3]

Intake manifold replaced and back on the road today. Fingers crossed that's it. I'm unclear as to whether it was the manifold that was faulty or its connections to the engine. I did ask to see the old manifold but for whatever reason that didn't happen. Now I hope for some trouble free motoring to come to restore my faith in the car and brand.

[IndusD4]

Fingers crossed!

Hi Guys, just joined, my first post.
I have a2017 td6 SE. The vehicle has been terrific except when towing my 3 tonne caravan. The restricted performance will only usually occur on the 2nd day when on cruise control and when trying to overtake another vehicle at 100kmh, just when l get passed that vehicle l loose power and have to pull over. I have found that switching the engine off and waiting 5 - 6 mins the engine has reset.
I have had the vehicle back 3 times and as previous posts the dealer states they had found the problem ( vacuum seal on hose ??). Today after 11months Of COVID and 2nd day on road the same occurred again. The other issue is the engine symbol came on (yellow) an hour or so before. I guess l’ll be going back when we return to Melbourne at Xmas. Luckily l have a 5 year warranty. The dealer actually contacted someone in the UK to see if they had come across this, no result found. Hope this may help some others that have a similar problem. Cheers Peter

I've not heard of this with a D5, but there were reports with the D4 years ago with people towing and getting restricted performance issues while on cruise control.

When towing, does the car recognise the van is attached (green trailer symbol flashing on the dash with indicators)? You mention the engine warning light comes on about an hour before this happens, do you know what fault codes are logged when this happens?

Pretty sure caused by high EGT's.

There are a few D5s on Gumtree at the moment which seems strange for 2 year old cars. No leases would be up.

There are two on Gumtree. One dealer and one private. Can't imagine why someone would buy a $100k car through Gumtree.

people change or lose jobs, lots of leases would be aligned with employment. Who knows but it’s good for me, someone else can take the first year 30% hit and I’ll take it from there

I’ve leased on 2 years before. It is possible

[scarry]

Two years old so not much warranty left,will need the extended warranty, or I wouldn't go near one.

Why? 2 warranty claims on my vehicle is all it had and one was a creak in the dash, the other a broken seat foam.

If they’ve been stable for the warranty period they generally won’t have a problem.

Agree with Tombie and Lukeis

Love buying cars with some of last year of warranty left when I do infrequently buy one because;

A) 30% depreciation
B) even if it was back into the dealer 110 times from new there comes a point where every conceivable part has been replaced and the problem resolved along with factory updates to software etc. (D3 got a CANBUS update in 3rd year) This occurs at exactly the same moment the first owner’s will to live is broken and they sell in despair and hatred.

I then have the balance of warranty to see out any concerns.

This is playing out now with the D5 and new Defer.

I had one minor warranty claim on mine where the steering uni was replaced (I think) and got a new leather steering wheel for the fretting rubberised one. That was 10 years ago now and never had a moment’s trouble since ( touch wood).

Mine had more issues out of warranty than while in warranty, started at the 4 yr mark and it was low K's.

Every vehicle is different, its pot luck most of the time.

As you would know, it doesn't take much of an issue with a vehicle like the OP's,to cost thousands to repair.

Thats one of the reasons these vehicles have such huge depreciation.

Anyway,its whatever people want to do.

Yep Paul, you nailed it on the depreciation.
A new RR Vogue is 250k, three years later it’s 90k. This is because no one is going to take a 190k punt on a car with no more warranty, least of all one from LR.

im looking for a 2019 D5 now as it’s not too much more than the 2017/18’s but for that price it’s nice to know it will have a bit of warranty to go, peace of mind since I’ll actually be putting it through it’s paces towing and off-roading which the last driver may not have done yet
