The law of sod strikes, not a great time for haldex pump to fail. 4x2 just isn't ideal today.
New one ordered. Will get that sorted the see about the egr issue that's been Intermittent for the last few days. 😖

Are you sure its a pump failure, not a poor electrical connection or blocked screen filter.

FWIW when mine failed I got no dashboard warnings or error codes - just a dead pump on bench testing at Bell Engineering. Jules

No it's had the "gearbox fault traction reduced" message on the dash.
Reading the codes with my Autel showed p1889-15 pump pressure reduced (or something similar) which according to Autofaultfinder website is a symptom of a failing or failed pump.
I ordered a pump, filter and oil kit from Ebay yesterday which amazingly was delivered today.
Spent a few hours this evening crawling around on a cold garage floor removing the haldex unit, replacing pump and filter and rebuilding before filling with new oil.
Fault code gone, 4wd restored and a drive up our deeply snow covered lane and untreated rural road proving that terrain response working perfectly.
The egr fault message has not returned today so it's possibly going to be Intermittent, will have to get it sorted though. Landrover - turning owners into mechanics since 1948

Good work Bobupndown…..!
Nice when things go as they should….
Further to recent posts on Haldex servicing ……was the pump “gunged-up” or nice & clean ? Ditto the filter ?
Nice job…..

well done Bob  Jules

The EGR fault became more persistent until I was getting limp mode and engine management light on virtually permanently. Car also shuddering quite a lot between 1500-2000 rpm. I'm normally willing to get stuck in and tackle most jobs myself as far as cars go but this has been described as a challenge by a few members on here. Coupled with the knowledge that I'd need to get in air path calibration done afterwards which I don't have the kit to do I decided to bite the bullet and book it into an indy. Duly dropped it off and got the call that in addition to the egr valve they strongly recommended replacing the egr cooler as well. Given that these are a known issue I agreed for it to be replaced too. They waited a few days to get delivery of the genuine LR cooler and then completed the job. After paying a rather eye watering bill I picked it up. Driving home however I noted with dismay that although the performance was OK the juddering at certain speeds around upward gear changes persisted.
I'd thought that this symptom had been related to the egr fault. Put the code reader on it but it's not showing any faults (apart from a random hvac blend motor issue that hasn't caused me any concern for some time). Put an injector cleaner into a fresh tank of diesel and will see if that has any effect tomorrow on a 50ish mile drive.
Taking it back to the indy on Monday for them to check it anyway.
Reading other threads on here has me concerned that it may be an auto gearbox / torque converter issue but I'm hoping not because I do routinely change the autobox oil to keep it healthy.
Crank position sensors can also give these symptoms apparently.

Well indy had it for a full day, they confirmed that driving the car produces the shuddering fault but they cannot determine the cause. No fault codes being displayed. They re flashed the gearbox software and were even able to tell that my car should have 17" wheels rather than the 18" wheels which have been on it for years. They altered the software to confirm that but no difference. They are adamant that the new Egr is working as it should and to be fair there are no dashboard warnings or codes when I read it. Driving the car in Sport mode seems to reduce the issue.
They suggest driving it until it either displays a fault code or gets worse!
Amazed they didn't suggest or enquire if the gearbox oil has ever actually been changed, (it has). I thought that would have been an obvious step and another few £££ for them.
So that's my next step, either another full diy gearbox oil change using the gibbons method and a dose of tranny fix (must be careful how I order that 🫣)

to confirm if it is indeed a gearbox issue and hopefully resolve the issue or take it to a gearbox specialist for a mega flush type procedure. Landrover - turning owners into mechanics since 1948

Good luck , let us know how you get on . FL2 SD4 XS 2013 Orkney Grey

Mine was juddering between 1500 and 1800/2000rpm...wasnt sure what it was but it was eventually diagnosed as a worn torque converter in the gearbox. These do wear apparently and can cause shudder as they lock up.

Tried the DR Tranny instant shudder fix and a few drain and fills but to no avail.

Also driving in sport avoids the issue somewhat as it forces the car to rev higher thereby avoiding the 1500 rpm lockup rev range. I did the same for a while to bypass the issue so it was drivable until I had it fixed.

Went for a full reconditioned gearbox and it now drives superbly with no judder and a smooth delivery of torque from 1200 rpm all the way through. Not a cheap fix but im going to keep the car for a while.

Its easy to confuse diagnosis on these cars- haldex pump/ptu /wheel bearing/drivetrain judder/egr not closing fully etc all can mix in with one another,.

I've had 2 SD4s over the years and they have both suffered from (engine?) noise/vibration around 1800 on medium throttle. This is on very, very, rare conditions on a couple of particular slopes on at about 30mph. Applying more throttle, forcing downchange, immediately solves problem.

It so rare and only on a couple of 30mph limited slopes that I have come to accept it as a feature of the SD4 set up.

My best bet is that it is due to the turbo vanes not being able to find the correct position (perhaps stalling) and thus causing the actuator to clatter.

Please note that I tend to drive in Speed Restricted Areas in Cruise Control, and this tends to lead to my SD4 using light throttle and low revs. FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)

My car had always driven perfectly though, no hesitation or shudder of any sort until recently. Maybe it's just a coincidence that it appeared around the same time as my EGR problem?
I'll give it a gearbox flush and a couple of shots of Dr Tranny next weekend and see how it goes from there. Landrover - turning owners into mechanics since 1948

Have you seen this (Volvo) Article on Auto Gearbox 'Flaring'.

I had it on my 2010 SD4 -Early Facelift- XS, and I think it was an indication of low pressure in the Auto Box Valve Unit.
