Thread: Disco 4 Engine System Failure Warning - beware!

Damn, damn, damn. I HATE sitting in the front of a flat bed truck towing a camper trailer with a d4 on the back tray (7100km's on the odo) and having TOYO owners point!!!!!!!!

Up until today - 10 great days in the new D4 towing Adventure Camper Trailer; Adelaide - Swan Hill - Omeo (via Hotham, yes up those steep hills, trouble free!), Wonangatta (Dargo), Ballarat, ....home...well ALMOST, filled up at Tailem Bend and lasted about 10clicks, up first big hill on the SE freeway, cruise on 100km/hr, suddenly big drop in power and "Engine System Fault" warning etc. Sighhhhhhhhhhhhhhhhhhhhhhhh. We tried starting again, were told by LR Assist to open and close doors 3 times ("to reset computer") all to no avail. So the ignomy of the tray back and pointed fingers.

Sigh

I'll update once cause is known.

On the plus side we had a great holiday and D4 was awesome doing everything especially tracks like Bill Goat bluff etc.

Cheers (need a drink tonight)

Hi Chris,
Had mine in at ULR Malvern this week for the Power Upgrade Module, only to find out that this upgrade had been done (along with others) at my last service which was just before Christmas.
No problems since............running like a clock.
Interested to know your outcome.
Cheers, Craig

Craig, what does the Power Upgrade Module mean? Is it a replacement for the engine's management computer? I love some of the terms some manufacturers use for fixes for problems. When Honda's had some pinging in the new shape Euro's they came out and said this is a problem with the knock sensors not doing their job properly with some of the petrol we get in Australia (ie crap petrol at times). They did a software reprogram and after that if it still pinged they swapped in new knock sensors that they had been testing and developing since the problem was first reported in Australia (a problem that did not affect driveability and was a post combustion sound not a true ping ). They also told Wheels who then publicised it that they warranty the motor for the whole time that the vehicle was owned continuously by the first owner...now that's an engine warranty.

Have LR actually even acknowledged the problem? Have they said it is a fault and what it is exactly? I am keen to know why this is happening.



Cheers

I'll update everyone as soon as mine is ready.

Sorry to hear of your woes Chris, are you suspecting the fuel, or was that just a coincidence? This is the third fault like this I've heard of in the last 4 weeks - all towing a trailer or caravan. However, the others seemed fine after a reset. Can you recall the exact messages the car displayed and in what order they appeared?

Cheers,

Gordon

Ozscott,
The power module upgrade is part of the software upgrade.
As far as I am aware, its not a replacement part.
Coincidence that mine happened at 100Kph towing my boat on a flat road.
Cheers, Craig

Nothing yet guys - car is staying overnight.

Only one warning ever came up - red triangle and engine system failure. I had cruise on 100kmhr and it was beginning to labour up the hill we were on so as I dabbed the brakes to cancel the cruise - on came the warning and the power just disappeared. That was it. no other warnings. I tried to reset the computer and checked everything under the bonnet - air filter was "as new" (RAI certainly does its job!) and all else appeared Ok. The car sounded perfect and "rev'd" nicely. But it was down on power as soon as the warning came up. I tried to check the oil (using the dash readout) and it said "not available". No idea

I did have some electrical bugs with the dual battery set up - a fuse to the new 12v outlets in the back blew twice - but we think that was as the fridge cord had frayed from constant contact with the fridge slide. We ended up just using camper frridge and accordingly the second battery (read: Thumper in the boot space) was actually disconnected from Traxide system at the time this all happended anyway.

Hope to have some news tomorrow.

I should stress - up til then it was magnificent and the LLAMS Height adjustor was brilliant the whole trip - making some really tough sections of track sooooo much easier.!!

I'll add photos etc later!

Had a poke around the LR UK forum last night and there were a few reports that may link the 'Engine System Failure' warning to ditry fuel.
After reading this I realized that I had only filled with fuel about 15 Klm's prior to it happening.
The guys at ULR Malvern ran all sorts of checks and nothing came up. The vehicle has not missed a beat since????

Cheers, Craig
