Engine System Failure. Special Programs Off
Hi all,
Been getting the occasional "special programs off" with associated BONG when cranking from cold which I put down to a tired battery ... BUT...
The past couple of days shortly after starting and getting to the main road where I finally can get a bit up to speed, it BONGS with "EngineSystem Fault" and the associated loss of power. After 2 or 3 seconds it is followed by "Special Programs Off" or something similar and the lights on the Terrain Response knob go out. Attempting to use it results in "System Not Available" though the suspension raising/lowering works fine. At this point the power is back, and I didn't even stop ... just dropped it into 2nd gear due to the loss of speed following the system fault. Car then drives normally albeit without any Terrain Response working. Turning the car off and back on resets everything and everything works fine (Terrain Response included).
Fault codes mentioned something about turbocharger boost control, the EGR's, and a "knock sensor" fault of some sort? I don't have the exact codes as my indy checked them out and cleared them. My EGR's are blanked so I can safely ignore that fault. Leaving me with a knock sensor and turbocharger boost control fault. Indy told me to go boot it a bit to see if it comes up again, thinking the turbo actuator might be sticking. Engine was fully warmed up at this point. I floored it in all gears and no sign on the EngineSystem Fault.
I will get actual fault codes next time it happens but did anyone have anything similar? Am I about to join the CFT? or can the actuator be replaced independently of the actual turbo?
Thanks Dennis

I had the exact same symptoms, plus the suspension would lower. (dont know what my fault codes were). it happened about every 20 mins.
took it in to the main dealer who said it was a rusty ECU, which they replaced.
problem wasnt sorted. took it to an indy, who found a fuse gone (can't remember which one). this has sorted the problem.
when i had the problem, while looking up a solution on this site, it seemed others have had this problem due to blown brake light bulbs.

Hmm... in my case the suspension didn't lower. I also didn't get any lights on the dash. Just a bong and ENGINESYSTEM FAULT followed by SPECIAL PROGRAMS OFF. Haven't checked my fuses but I've been out flooring it around for over 2 hours since my indy cleared the faults and it hasn't done it again. Pulls well and drives well. Maybe it only does it when cold....
Apparently there is an actuator kit (LR023086) now. Might let my indy have a go at replacing that...Dennis

Right. 1 week later and the system fault hasn't come back. I am hammering it quite a bit though so it is very likely to be the turbo actuator arm or the variable vanes sticking. My thinking is that due to my hammering it while driving both are getting exercised so not being given time to stick. I can get the actuator arm replaced, but since that also requires the turbo to be removed, I was thinking of cleaning it out a bit too.
I do have a local turbocharger specialist that I still have to have a chat with but I'm wondering if there's anything in the D3's turbo that will not allow such an "operation".Dennis

Nighthawk, all the same symptoms as mine prior to 2nd replacement turbo. Might be the linkage, as failed on mine, whole turbo replaced as was done at the time.

Yep I'm pretty sure I'm on borrowed time at the moment.
I do see it a bit wasteful replacing the entire turbo if it's only some sticking vane due to carbon buildup. Hence my question about getting a turbo specialist to give the vanes a quick cleanup. I will be getting the linkage replaced as that was what was suggested to me by my indy, but since it's a turbo out job I thought of taking it for a clean while it was out of the vehicle.Dennis

With me it wasn't the veins, it was the linkage between the actuator & the veins. It wasn't springing back into position so system was getting into a strop. I also has MAP sensor problems and a bunging up fuel filter at the time so was a complicated picture to sort out for a non techie like me. The car was regularly shutting down with even gentle throttle increase, overtaking became totally unreliable & SWMBO refused to drive the car for several months. All sorted eventually, touch wood.

got the same problem on mine:
Hdc off
Engine fault
limited gears selectable
park break fault
P023D
U0138
U0151
U0121
U0101
U0416
So what is the best option to look at??
turned the car off the first time and restarted, got me about 6mins, then again fault...
turned off, put on the bas interface, cleared all... got me about 15min
then in front of my door, did again the faults.... turned it off, and started again, and got to where i needed to be 15mins later without problems... I heard about oil in the ECU as well in the TV6's....
So WHAt do I need to do, get the actuator kit??
the car is from 2008

That's many more errors than mine had. I only had 3 error codes, one of which is an EGR fault which I ignore because mine are blanked. I had no warnings about park break and HDC. In your case only P023D is turbo related (more specifically, it's about manifold pressure, but then mentions the turbocharger). The other faults are about lost communication with the various control modules.
Before you go down more expensive routes:
Is your battery in good shape? How old is it?
Is your alternator charging sufficiently? Put a multimeter on the battery and check voltage with engine running.
Did you check that your brake lights are not blown?
Or the brake light switch?
Clean the Manifold Air Pressure sensor too just to be sure.Dennis

Battery is brand new, its an very expensive BOSH grey model, should be the best one to replace the LR one with...

Alternator charged 14,1v last time I checked...
Did you check that your brake lights are not blown?
Got the LED lights, so should be no problem Or the brake light switch?
Don't know where this one is located... but will check this one... can only order parts after 9-1-2012... so will have to wait... Clean the Manifold Air Pressure sensor too just to be sure.
Cleaned the map only a few days ago so should be fine, but will check this later on today
now, If i need to change the turbo, are there any better models on the market to replace the standard one with?

The only thing I don't like is the non-genuine battery. I haven't heard too many success stories from people having used a non-genuine battery. But anyway, to each his own
Regarding changing the turbo, no there are no others. You will definitely have to go with the standard one.
I'm still awaiting a reply from a local turbo specialist about whether my turbo can be opened up and have it's vanes cleaned. Christmas slows down all communication . I'm pretty sure that 90% of all turbo failures are due to sticking vanes or actuator arms. The rest of the turbo is pretty simple. Unless the thing runs dry of oil it should go on forever (just like traditional, non-variable turbos).Dennis

had been a while without problems, had it again just now, while driving about 70mph, I shut the engine off, and restarted the car whilst driving, and the fault was gone

Ah the old rolling restart, as practised by those in Club ESF. Just don't take the keys out & be quick going up hill.

haha, will keep that in mind, this time I was not really going uphill
Bear in mind, rolling restart doesn't work when gearbox is in D

Wonder of anyone at LR is interested, or even aware, that their cars are shutting down on their drivers, somehow I doubt they give a monkeys? Mine did it on the M6 in front of a truck, not a happy experience. It probably did it 20 times or so til i had the turbo changed. SWMBO refused to drive the car or 9 months til it was eventually fixed. If she'd have had her way it would have been chopped.
