Thread: HELP

Hello friends,


I need your opinion.
I had a limited performance issue a few weeks ago.
with DTCs P1247, P0004D which I thought resolved.
But this weekend, it starts again with new DTCs
P2263, P0004D, P0235, P1247.
So I took the RRS to LAND ROVER and the diagnosis would be "Replacement of the 2 turbos" with the invoice being fine.
When do you think ?
Knowing that I erased the codes several times and each time the car runs normally afterwards.
If the turbos are failing it's not all the time?


thank you

The idea of a brand specialist in many situations is just marketing as all cars share the same systems and modes of operation.

Sure there are certainly times when it can help, or maybe even necessary, but not always for everything.

I also agree thats its highly unlikely that both turbos would be at fault at the same time, never say never.

But maybe the dealers logic is its one of them, and if one needs doing the other might not be far off, so do them both...

Looking at you dtc codes, theres even mention of the fuel regulator, see a problem with fuel supply, will product less power, and thus lower boost pressure than expected....

It could be simple as intercooler hose crack, though ud hope that has been checked.

The fact it can work fine after code clear is also very suspicious, possibly the fault is still there, but it takes time for the electronics to either notice it or decide its permanent enough to raise it as a error and or go into limp mode, and show engine light.


Turbos are the sort of thing that if you take the hose off and its still spinning freely and not excessive wobble, and has all its fins, it should still work fine.


It would be interesting to know if which if any codes came back right away after clear if any, though likely the dealer checked this.

I understand you are in a difficult situation, but you should at least ring around other machanics to see if they have any interest in checking it out, theres a fair chance they will have a snap-on or other brand diag tool that will work well enough on LR for investigation.
