towing on a flat road at 1800 rpm.esf stop take out key reset go again and after 120klms on a flat road 1800 rpm esf.same procedure at carry on.Does this 3 more times.then when towing a small toolbox trailer under load this time esf.REMOVE PIPE TO EGR VALVES. blank off.ok for 3 weeks.Have been told that i cant blank off my car MY08. so today removed left hand side egr as this was showing a fault on my reader.egr moving freely,i had previously removed both and found them seized up and serviced them. left side egr was ok but i still cleaned and refitted with all pipes,any ideas as to what could be causing this.I had taken car to a dealer and had the codes read but nothing comes up.i am due to go away with the van at the end of the month and feel i cant trust this car. cheers

Hi Bowrider

I assume you mean Engine System Fault. I've just been to QLD and back in my 2009 RRS, should be same motor, 2.7TDV6 and had this fault come up numerous times on the trip. Each time it occurred it was under load during an overtake, not a great time to get restricted performance, however I did notice that during restricted performance, if you put your foot to the floor, it would over ride the performance restriction, I suppose a safety feature.

Keen to hear the outcome, as I can't make the fault re occur around town, but seems to happen after some time on the highway first.

As mentioned it occurred about 10 times on route to Qld and back, previously it had occurred about 3-4 times in 12 months.

I'm off to my independent on Tuesday to get it looked at, the day before I headed to Qld, it happened and they put their computer on the car, which showed a turbo related fault, but said that as it has reset, they wouldn't start anything as it could be a couple of items causing the fault.

Let us know how you go.

Cheers

Andrew

Sorry should have said Boardrider.

[boardrider]

hi kingo.
u r correct.it is system fault.as i have explained it was not under load on the first part and barley on the throttle,so not under load.on that occasion i feel it was a load of bad fuel,Green in colour bought at brunswick heads.Have been told it was winter fuel,go figure at that point as it is on the coast and was in the middle of october.The last time it did it was coming into buladealah,again not under load,The last stretch to home was about 210klms all good.The other time i refered to was underload towing a toolbox trailer.Just the other day it did it again without anything on the back and not under load.On each occasion i did try putting the boot in but nothing had to pull over and reset.This has been going now for almost 2 years.i have had it on the autologic and shows nothing that could a definite.its almost time to get rid of it
boardrider:confused:

[~Rich~]

Yeah I agree it sounds like a bad batch of fuel, have you refilled since with fuel from a large known brand? If you have it also makes sense if it's getting better as there is less crap left.

Bad fuel can do all sorts of damage to newer diesel engines, hopefully you escaped this.

Maybe best to get the tank flushed and a new fuel filter fitted as well.
This can happen to any vehicle, not really fault of the make.

[scarry]

Delaminating hoses on the intercooler can also cause this issue.

[boardrider]

hi scarry,that is one thing i am going to check out thanks
rich. i have filled up a number of time since then and feel that fuel is well and truly gone.on only fill up at BP or CALTEX.when i came back from that trip with the green fuel i changed the fuel filter just in case.
cheers for the replies

hi, update on my problem.
last weekend i removed the blanking and serviced the left side egr valve that was showing a fault.put back together and tested with the van on up a really good hill,where i have had an issue b4.All good.i am picking up a new silicone intercooler hose and fitting to be on the safe side.I did remove the existing hose and no obvious splits but who knows how bad it is.I am going on a trip to the sunshine coast in a couple of days,so here is hoping the issue is resolved.I will post the outcome when i get back.
thanks for the imput
boardrider :cool:

[boardrider]

hi guys,
another update. Picked up my new silicone intercooler hose from allfourx4 near newcastle.At the time i asked for some advice on my issue,the accessory guy put my car on the autologic.came up with 4 faults linked to the air flow and gas flow all of which may be effected by a faulty intercooler hose.Well i fitted the hose and straight away a noticable improvement in driveability and fuel consumption inproved.My suggestion is if anyone does experiences another esf that could be related to air flows maybe it could be the intercooler hose.
cheers :cool:

i all,update on my problem.i have change the intercooler hose.went on a trip monday.heading into a strong wind only got 135klms,esf warning,lose of power,pulled over removed key reset,continued on.Only got another 35klms.same thing,same fix.This happened one more then 10klms later heading up a very steep hill,complete and very quick limp mode,very dangerous,stopped me in my tracks with a long line of cars behind.Just managed to get the car and van off the road,reset as b4 but decided to turn around and go home,with the wind. An hour later i stopped at the same place as i did b4 going and removed the pollen filter,a bit dirty,cleaned as best i could.Also cleaned the MAF sensor,put back together and went at the trip for a second attempt,All good for one hour till i got to the exact same hill in the exact same place complete shutdown,pulled over,reset but decided to continue,but this time when i came to a hill moved out if sport mode into manual shift and this did work for the next 200klms. My thoughts,could the pollen filter cause such a meltdown or are there other things that couls cause this.It may require a trip to a specialst landrover mechanic if i cant find a solution,Any suggestions would be greatly appreciated thanks :censored:

Hi Boardrider

I have had the same issue for the last month, but more intermittent. Then last week it became permanent and it was diagnosed as a faulty Turbo, $6000.00!!!

I rang around and took it to MR Automotive in Brisbane for a second opinion and they called a few hours later saying all fixed. A sticking turbo actuator $240.00!

I only picked it up yesterday, but it seems to have a lot more power and no ESF lights. Hopefully all good and if it is I will have it cleaned yearly.

Hopefully yours is as simple.

[kingo]

Hi Fitzy, my RRS 2.7TDV6 has also been throwing up faults, that appear to be turbo related. It only occurs after some time on the freeway and when overtaking, at the end of the overtake when you are coming off the throttle a fault would sometimes appear, but not always.

What are the circumstances when your car went into restricted performance.

Thanks Andrew

[Fitzy2011]

Hi Andrew

I can't really say it happened under any specific circumstances but putting it in to command mode (sport) usually made it drivable. But I have just come in from a drive where I stuck it to it a bit and it is very very good.!

[boardrider]

hi fitzy, thanks for that.i have checked mine on start up and shutdown and appears to be ok,but thanks will investigate again.
i am getting a new pollen filter tomorrow and will be heading home with the van on sunday,so that should test it,I took out the pollen filter and put a foam pad at the air intake of the snorkel and have done 200klms today,uphills and down dales and the car went well.The test will be with 3,2 tonne of van on the back.:angel:

[shanegtr]

does it throw any error messages up on the dash or just the fault lights?

[kingo]

Mine doesn't throw up any lights, just the "Engine System Fault" message on the display and power is reduced. A stop and restart clears the fault and full power is restored.

[Fitzy2011]

Mine also was just Engine System Faul and nothing else. Also came and went a few times but eventually stayed, with dramatic loss of power but also ran not toooo bad in command shift!

Running really well now though!
