* Time Bomb Alert * EGR to Left Hand Manifold pipe LR020547

I don't post very often but this I had to share, as it is likely to affect all vehicles with the 3.0 tdv6/sdv6 engine at some point in later life, or earlier depending on driving history.

Friday 13th is apt, sorry no good news here, all bad.

So, my MY2010 TDV6 lost 1st stage boost around 3 months ago. I knew the turbos were probably OK as both were checked when I had a new JLR engine recently (yes -Broken Crank). Anyhow, with the radio off l noticed the sound of rushing air within the cabin, passenger side, when pulling away or mild acceleration. it sounds like it was coming through air vents, but it was not.

I assumed a leaking Boost pipe of which there are many components between turbo and Manifold.

I knew some were fiddly to get at, so I booked into my indie.

Diagnosis was a surprise - the issue was a leaking pipe from exhaust to EGR valve. Hence robbing the 1st stage turbo of initial pressure, hence the loss of power. Boost pipes were fine.

Good news was that the part was only £56 retail (part no LR020547)
BAD NEWS: This part (at time of writing) is on back order and Genuine ONLY - even Main Dealers cannot get any or any ETA !

The car is drivable, but concerned about fumes entering the cabin, which they must be as I can smell exhaust. I placed a CO meter inside, fortunately zero ppm reading, but still not happy driving, hence sourced a second hand EGR, complete with LR020547 Pipe attached.

Now, this is the concerning bit for every other owner. I thought I'd check the second hand pipe was sound before tackling the fitting. I removed the fireproof fabric braiding/heatshield which is crimped at one end(check LR020547 on google for pics), and cleaned off all the burnt-on carbon from the manifold end of the pipe.

Then I saw the issue.

The pipe, which i think must be stainless steel, is very thin and must take a huge amount of heat abuse from the hot gasses being so close to the manifold, compounded by the carbon which must focus/store the heat over time. This seems to have eroded and buckled the pipe to such an extent that it is pin-holed and therefore leaking.

I have not removed mine from the car yet, but this is what must have happened and got so bad that there is a large hole/crack affecting boost and emitting exhaust into the engine bay. I will know more when I do the job (maybe tomorrow).

I conclude that every vehicle with this part (Landrover/Jaguar/Range Rover) will be at risk. Mine went at 12 years old/ 195K miles. Yes that is High but nevertheless I think it is a design issue placing something so delicate/thin close to the manifold. Draw your own conclusions from the pics.

Maybe the part supply shortage is the result of many starting to fail ?

Yours may already be like this, I doubt a hole this tiny would affect boost yet but I'm sure all will get worse over time.

MAY BE WORTH CHECKING - if yours is till under warranty the JLR must surely get it done as exhaust is meant to exit at the rear of the car or recirculated, not inhaled by the passengers !

Maybe with group action this should be a SAFETY RECALL ?

Just though I'd add - No engine management lights showed this up, or GAP IID errors !

PPS. If the studs break while removing it, its a body-off job. Hence £56 part £1200 fitting.

Never personally seen the LH pipe corrode through, it's usually the RH

And usually, the bolts snap Big Cry

Cheers, seems out of stock too.

I may have to resort to slotting in a blanking plate until I can get a pipe. I know DPF regen will be Censored for a while but better than poisoning the occupants.

Fingers crossed on the studs tomorrow.

reckon warm the engine up first, expand the threads a bit.

I have a very similar problem. How did you gain access to this pipe - wheelarch, or from the top?
Cheers
Andy

Hi,

I've been searching for this topic on the Range Rover forums but this is the only place I can see that mentions it.
I have the same problem with the driver side pipe and wondered if this could be done without taking the body off even if a bolt snapped.

Cheers Andy.

I am certain that, as an interim measure, any competent welder could sort that. Cool

No, this seems "reaching" to me. Even if you are the original owner... 195k miles. 24 years old. I'm not seeing it.
