Thread: Engine system fault

I think Graeme's point is that as legislation changes around the world, so too must the characteristics of an engine that is targeted for that market. A vehicle that can have its performance characteristics varied via software updates is obviously the more economical option for the manufacturer.

This then leads to the option of being able to update an existing vehicle as different performance characteristics are explored by the design engineers. Take as an example after-market tuners. Their maps are continually improved, and the ability to flash them into the ECM is what makes this financially feasible for them. So there will always be software updates.

In terms of rectifying actual faults, software can never be 100% foolproof. On the one hand there is generally less faulting of software systems in comparison with purely mechanical systems (which need constant adjusting). On the other though, software faults can propagate through to quite unrelated systems, something that rarely happens with mechanical systems. In the software system, it is impossible to test every combination and permutation of signal paths and environment. But given that this is the reality, I'd prefer the ability to have them fixed via free software updates. I think most people would.

Cheers,

Gordon

I agree that LR have been tardy with fixing their s/w bugs but hope that performance, or rather non-performance s/w issues should be history now. However they still haven't properly sorted the cruise control button use. I'm not referring to the inadequate checking of current speed and failure to timely adjust fueling to prevent excessive over or under speed, rather that if resume is pressed whilst overspeed then speed increase is pressed within 1 or 2 seconds, setspeed is changed to the current speed. Once CC is enabled, the increase and decrease buttons should only increase and decrease speed, never setting the setspeed to the current speed. LR s/w seems to often be sloppy.

Had the D4 into Bruce Lynton to get the fault checked and a 2year service too. Turns out it was as expected a software update that was required.

I also mentioned to them a dashboard creaking noise that comes from the R/h side of the dash when travelling on a patchy or rough road. Turns out they had had several of them with the same problem. The reason is the dashboard locating pins rubbing on the gromits that sit in the firewall/ body of the vehicle, so the dash has to come out. It's a all day job for another day.

Has anyone else experanced this dashboard creaking noise?

I wonder how much those software updates are going to cost once the vehicle is out of warranty?They do seem a common issue.

The dash in mine seems to sort of buzz on the drivers side on certain road surfaces.

Only slightly annoying,so have been putting up with it so far.

This is a clear, short "creak" noise that sounds when the road is uneven or patchy, so I guess when the body is flexing. The noise fits in with what the dealer was describing.

Hi Craig, no dash squeak from my D4 3.0L, but back to your original post.
On 10th Jan, was returning home from a day on Rainbow Beach, heading South to Sunshine Coast, when I experienced the 'Dreaded' Red triangle, and associated Degraded power warning, and the car had gone into limp mode.
My son contacted LR assist, while I continued along the motorway. They suggested we pull over, and reset the Computer by the doors shutting method.
Just before pulling over, I got the Amber Engine fault Logo come on. Resetting actions did not clear faults, so continued home in low power Limp mode.
Flatbedded to LR Dealership early next morning.
Dealership could not do anything till 14th, due prior workload. Various checks carried out, and on 15th, were going to change Turbo Actuator, as the operating rod was suspect. Checked progress this morning, 17th, and was told that LR Australia are requesting a whole host of further checks, wiring looms amongst them.I didn't ask if Actuator had achieved anything, but looks like these other checks are a prelude to a Turbo change, involving body off procedure.
Further time car is in garage, and as I have a Club Camping week planned for 21-25th, I have had to De-Mothball my trusty 100 Series LC.
My D4 is a MY11 with 19,000 Kms. It had an oil change at 8600kms, and again at 14600 when having it's Annual/26,000 service.
Limp home mode is a great option to have if you are getting home from the shops, or have Highway all the way home, but any thing other than that, upsets alot of fellow motorists, and one has to be 'Thick Skinned' to ignore their reactions.
Will keep this thread updated with the outcome.
Don.

Once the vehicle is out of warranty,i wonder how 'free' these will be,particularly if the vehicle is not serviced at a dealer

Craig - yes. The dealer attempted to fix it with some special expanding foam stuff they have ($85 a bottle). They say it is not a dash out repair.

After the corrugations from my Broome trip, the fix didn't work. I had 48,000km service last week and they were out of stock of the foam - so will get it done when they say it is in.
