L322 TDV8 - Turbos gone.
Discussion
Ahhhh...... I knew it was too good to be true, after 18 months of trouble free (well almost) it's gone and done it to me...
No messages, but a sudden loss of low down power, smoke and crud out the back end when trying to accelerate, nothing below about 2K revs before the power does come in. Took it to the garage this morning for the diags, left hand air flow sitting at 10% of right hand at tick over. Diagnosed to be the left hand turbo stuck, suggested to get both done at same time as when 1 goes it's either because the other caused it, or it will have damaged the other, or the other won't be far behind.
Prices, for a pair: from JLR - about £4k(+vat), without JLR logo'd box - £2000(+vat), or from Ebay - £1050.
8 hours to fit plus all the bits and bobs, so looking at probably £2.5K all in.
Still, it has done over 125K miles so probably due something like this.

Interesting.... it's not the turbos. They were replaced and although one was starting to oil up, they haven't cured the problem. The garage is a bit stumped as they've not seen one do this before and the EMC is not triggering warnings.
Basically, below 2k revs... no power. Once the engine eventually manages to chugg up to about 1800 revs it starts picking up and then is as normal.
So if I drive the car at 2k revs and above using the gears manually it's all good, if the revs drop below 1500 or so it's got nothing.
The passenger side exhaust smokes unburnt diesel big time when the car is first started but that calms down after 5 minutes and the car warms up. When driving, it's throwing a lot of black smoke out that side when the engine is under 2K revs and I'm trying to get back up to 2k revs again.
I've done some digging around the Topix website and it could be something connected with the Intake port deactivation actuator, the garage are going to investigate next week.
Anyone have a TDV8 do something similar?

I presume they will have checked the hoses?
I had exactly the same symptoms twice and it was a cheap and easy hose fix.
If it's been looked at properly though, surely they would have noticed this.
Yeah, indeed, they a very well respected , experienced Range Rover specialists so have checked all the usual suspects. I actually had the turbo hoses replaced in the first week I bought the car a couple of years back, they diagnosed that over the phone as I was driving home.

They're saying this is a new one for them, they not seen a TDV8 act like this before, and their contacts at Landrover are equally stumped. Apparently the guys at LR have suggested taking off the intake manifold to investigate, which would appear to align with what I saw on Topix, there's an actuator valve that controls low/high speed swirl in the intake manifolds, depending on the design on the intake it could be that the low speed swirl path has somehow become blocked... that could potentially cause the car to act like it is.
Sorry if it's a stupid question, but have they checked the MAF?
I spent ages dicking about with a mates car - took off the turbo and it was fine. All the fault codes (read by a gebuine marque garage) referenced a turbo problem, but replacing the MAF cured it.
I could have done that in 10 minutes and saved myself a lot of time and skinned knuckles!

Hi All, this is NOT the same as split hoses, I had those in my first week of ownership.
The lack of power is almost absolute from tickover up to 1800 or so revs. When you press the accelerator nothing happens for a few seconds then the engine starts to slow rev up and at about 1500 or so it starts to gather pace until 2k revs when it feels completely normal.
To get the car out of my sloped drive, I had to let the engine warm up (lumpy tickover and smoke from passenger exhaust for 5 mins) , then hold the brake pedal whilst putting the car in gear and then allowing the engine get up to 2k revs before releasing the brake.
Any attempt to engage drive and just drive out normally left my car rolling down the slope as there was no engine power at low revs.

Ok, to close out the thread for anyone that might find it on a google search...
It turned out to be one of the EGRs. But a failure that the garage had never seen before.
The EGRs had been replaced about 40K miles ago by the previous owner, I have a receipt for it. However, it would appear he's used non JLR, pattern parts from China I guess. The ones on the car had black plastic covers, not white like JLR ones.
Anyways , the garage had spent some time scratching their heads on this issue as the symptoms were so pronounced and yet there was nothing being flagged on the engine management system as broken, certainly no errors relating to EGRs. The car was undriveable but no errors flagged. All obvious checks had found nothing untoward.
So they checked lots of stuff and eventually started stripping it down and removed the EGRs to find that on one side, the 10p sized head of the valve rod had snapped off. The EGR operated perfectly, the rods moved exactly as it should, unfortunately it just didn't have anything left on the end of it to close the valve, so effectively the EGR valve was 100% open even when the EM system had every indication that is was correctly shut.
Two new JLR EGRs fitted and all is good, car just needs some italian tuning to get all the crap out of the pipes.
I've been using my XKR for the last 3 weeks, but it's lovely to have the FFRR back, it just floats over the roads and yet goes like stink when you floor it, I'd forgotten just how quick the TDV8s are! And with instruction from the garage to give it some for a few hundred miles I'm certainly going to make the most of it. New turbos, new EGRS, all good to go!

Are they paying for the 2 x turbos and fitting?
I wish. To be fair seeing the state of the old ones I'm happy they did need replacing. I'm also pretty sure the garage hasn't booked anywhere near all the time they actually spent on sorting it, the time on the invoice is minimal.
So I've had both turbos and EGRs replaced for about the same cost as it would have been just to buy the Turbos. I'm happy with that.
Hi Hopefully they checked the inlet manifold too as when the EGR's stick the hot air melts the plastic inlet and the molten plastic mainly blows outwards but lots go thru the engine, 2.7 TDI does this a lot along with sticking variable vanes in the turbo, along with the dreaded inlet coking

If the OP is happy then fair enough.They must have had reason to believe they were contributing with either stuck vanes, loads of end float or damaged impellors/compressors.
Did they show you the old ones and the reasons why they considered both to be at fault? Theres normally significant smoke/noise/loss of power when 1 turbo goes let alone both.
