Thread: DonDownUnder's D3 dropping into Limp Mode

I'll blet pulling the rest of that "Y" manifold and giving it a good clean when I service the car on Saturday.

When you pull the Y piece just remember there are o rings on the end of the Y so be sure not to damage them, also if the EGR pipes are still connected a pair of long nose pliers and take it easy and you should be able to re use them .

Unfortunately the problem has reoccurred but I'm very confident I have the issue circled. I'm sure it is turbo related. A quick search on the Ford Territory forums informs me that there are more than a few people who have encountered this problem with their Territory Diesels which obviously shares the same TDV6 power plant. For these unfortunate people, it seems the dealer would run round in circles trying to find the problem but could not pin point it. Interestingly, no corresponding fault code would appear but the one thing they all shared in common is that they towed caravans and they all had scary encounters, much like you, Don, having to pull over in a hurry and cycle the ignition. A new turbo charger was the solution. There's a YouTube video of a Disco 3 owner in the U.K. with the same problem and symptoms. He replaced his turbo at home and problem was solved. Don, when you had the new long motor installed, they threw the old turbo back on, which is why I expect the problem still persisted. Either way, this weekend I intend to do a thorough check of the compressor shaft play, boost actuator and check for compromised seals.
I reckon 200,000klm for a small turbo is a good run. My Patrol ute's packed up at 150,000.
Anyone know a reasonable turbo supplier? I don't mind after market, as long as they're proven.
I'll be replacing it myself.
Cheers!

Sorry - not wanting to sound too critical but if you read back through your posts if you had actually replaced everything that you have decided the issue was you would could have bought a new Disco.

Now on some same vague story you are wanting to replace the turbo even though there is not actual indication you have a turbo problem.

Yes you can replace parts until you have replaced everything and the problem is fixed (afterall that is what the dealers do) or actually diagnose the issue.

As I said the issue you have is well known all over the world - read the international Disco/RRS forums, my car does it and I know there is nothing mechanically wrong with it. I suspect the software writers did not adequately take into account the actual manifold pressure when under heavy load like towing - but I don't know - other than routine maintenance like cleaning the MAP sensor (I will replace it next service) I adjust my driving to suit.

By all means get the turbo replaced - I think that is a body off job and pay the associated thousands of $$$$$ but I bet you still have the same issue after.

Don't floor the accelerator, gently bring it up to full power over a few seconds and you will not suffer the problem nearly as much.

Good luck with it.

I don't think you sound critical and I can appreciate what you're saying however I can only go with the process of trial and error. Thankfully, though unfortunate, Don has already eliminated a fair chunk of expensive parts that I would've been concerned about. I think your theory on the software is plausible, however most people with TDV6's don't suffer this issue. They're all running the same ECU software with the same set parameters. Last night I had to make a dash to Bathurst hospital and triggered limp mode without WOT. I was sitting on 100 but never really planted the foot. An acceleration lag was certainly noticible. In the end, I have two options. Find the problem or sell the car as my wife is scared of it. I can't see me getting my money back when I tell the potential buyer about the problem. I'd rather spend a grand and two days labour than dump it and loose a much larger sum of $$. Like I said before, 200,000 isn't bad for a little turbo. I will try and inspect it before I order a new one and tackle the job. It's not a body off job, but a painful one to say at the least.Just out of curiosity, Did you have your turbo checked?

Have you fitted a new MAP sensor yet?

Not yet. Cleaned it. Anyone used a multimeter on these? I'll have a look through Don's receipts but I think it may have been swapped out already.

Oh - I may have misread some earlier posts as I thought that the issue only popped up when towing (like mine).

So if you got limp mode without towing something then yes there is something else going on.

My point about replacing stuff remains valid and thanks for not taking it critically as was not intended - on this forum you will see dealers in particular just replacing things until they have fixed the issue only to have the problem return and ultimately solved with input form AULRO members.

On this last incident - have you had time to get the codes read?

Also the cost of a new MAP sensor is not a lot so as Graeme has suggested it might be worth replacing.

Also and I am going into an area I know nothing about - you have a suspicion about the turbo but in themselves they are pretty reliable however the actuator sticks - thinking out aloud is the actuator sticking and not allowing the vanes to go to the right position so causing the problem.

Maybe someone who knows could tell up if this is feasible and if the actuator can be serviced in place.

Irrespective I would replace the MAP sensor.

Good luck

PS - no checking of the turbo as yet.

I have an idea.
Get an aftermarket re-map done,get a few more horsies,better economy and see if the issue goes.
Its got to be cheaper than throwing a turbo at it,and less painfull.
