What sort of EGR "fix"?

There’s a service campaign for EGR rod. Had mine done. Doesn’t make any difference. I think it’s a precautionary. Not sure it’s a check or replacement.

My engine light is on and I'm having the EGR rod done under the assumption that will fix it, and then the cruise control will start to work again & adblue use reduce to normal Grenadier levels?? Fingers crossed

My engine came on last week. Took it to the dealers and they told me from factory the O2 sensors plugs had been mixed up because they look identical. All fixed now. Fun and games.

Today they sent me a quality survey. I told the truth.

Heh heh… I stretched my fuel economy a little far on the highway today at 14.4L/100 all highway. Averaging 99KMH

The “remaining range” box dropped off at 55Km to “- -“ yet I still had 20Km to go to the nearest fuel.
Alas I pressed on.

I turned off all electrical consumables, and set my fridge to idle in attempt at taking the load off the alternator. Not sure if it made any difference.

The fuel indicator still showed 3 or 4 bars on the red vertical bit… coasted into the BP Station.

Pumped in 90.95L of diesel. To the top of the filler neck.

Now I know I have 613KM of range at highway speed on a full tank. I won’t be playing this game again any time soon… Haha View attachment 7858879

Had call from dealer earlier, going in week on Monday, will mention this if it's not sorted, thanks

Just hope that @Jean Mercier doesn't read this thread, boy is he going to be envious, you must now be the closest tank emptier.

I read it, and am not envious, because:

My car is gasoline
MY record was 91.87 liters

You can find my post on February 20 in the thread "what did you do with you Grenadier today"

My AdBlue consumption for the first 6k Km was about 6L. So about 1.6L per thousand miles. No towing or "off road" ...mainly a return highway run down the east coast of Aus. Brisbane to Hobart Tasmania. av speed about 90-95 kmh

Similar adblue consumption as my Grenadier - before I rejected it back to Ineos.
Now I have a new Defender - which like the Grenadier has a 3 litre straight 6 diesel. But, what is really different, is that I have now done 7,000 miles, and the Defender does not even want the adblue to be topped up.

TheDocAUS · Jun 27, 2024

Utility Wagon, fully loaded (around 3.4 tonne) with roofrack around 11.5 to 12 litres per 100km (varies depending on how fast I travel, the speed penalty applies above 90kph). Travelling on sealed Outback roads, soon to go off-road.

Ad blue still around 1 litre per 1,000km.

I hired a Defender diesel at Sydney airport a few years ago.
The adblue warning came on and then I parked about 20 kms later and the vehicle refused to start until the adblue was topped up.
I was nowhere near any place I could get adblue so I had to wait for Europcar to send out a service vehicle.
18,000 kms on my Grenadier and I have used one tank of Adblue and it now says I have >4,000 kms range left.

My Trialmaster Diesel car has just over 5000 km and in this time the diesel consumption has improved considerably. It started out consuming around 12.5 l/100 km on average. A few days ago, returning from the house in Montaña after the holidays, after spending several months there, we were fully loaded, plus five adults. After about a hundred and fifty km of travel at a "legal" speed of 120 km/h, I noticed that the average consumption was 9.3 l/100 km. I think this is excellent consumption for the car and how loaded it was.

4,000 miles on the clock an I am getting a consistent 25mpg (11.3l/100km) on my daily 45 mile commute round trip which includes a mix of fast trunk roads and stop-start traffic to get in and out of town.

On a weekend if I head into the countryside for a longer jaunt I can easily get 26.5mpg (10.6l/100km) if I'm sensible with the gas pedal and still don't struggle to keep up with the rest of traffic

The best fuel economy I've recorded to date is an average 27.1mpg (10.4l/100km) on a 70 mile trip each way which ironically involved a fully loaded vehicle and towing a large camping trailer. I can only put this down to driving at 50mph for most of the journey: I've noticed in general that the fuel efficiency drops off quickly above this speed, no doubt due to the barn door aerodynamics!

With 6000 miles on the clock, I frequently get 28 mpg on minor country roads on longer journeys.

I'm getting just over 11litres per 100km. It's a bit worse at sustained higher speeds, about 12.

There's no way the Defender does 38mpg. Even JLR don't claim that.

12l/100km is circa 19mpg.
By 'driving like a girl' on a motorway, I could get 26mpg from the Grenadire (before I rejected it) - and 38mpg from the 90.

Your first statement is incorrect

trobex · Sep 20, 2024

11.4L / 100km is what mine currently sits after the last 2700kms. Based on Assisi fuel fill up. We kind of drive it a little more aggressively than the locals their own vehicles.

Diesel - 600km of 100% sand driving over a week, 3 blokes and a full rear cargo area, various terrain from 80km/hr on hard packed and soft and rutted to inland tracks and gnarly soft tracks - 17.85L/100km for the week. This excluded the highway run up and back.

Landcruiser was more often then not in the mid 20’s on these trips.

Ha! Similar 17L p 100km on sand only. Less weighty children and reasonably packed rear. Although only tested on around 280km of sand but still close enough. Y62 comparison 26L+++.

Snap! I got a matching score driving around Aberdeenshire country roads over the weekend. The trick is to just avoid town/city driving which makes sense in a 3-ton truck

I live 130kms north of Perth in Western Australia, it’s windy, WA = windy always…

Anyway I am either into a headwind or a tail wind, average into is 15/16 per 100km on a good day and with the wind maybe 13, I have a full length roof rack and awning. That’s at 110kmh, I don’t drive conservatively.

Not complaining it is what it is, but it’s not fuel efficient by any stretch of the imagination. On the rare occasion and avoided at all costs I am in Perth it drops to 11ish. So highway driving is when it’s at its worst.

Recent towing of a 2t offroad van through outback WA for 3000k a was on average 18l per 100kms.

Adblue is not great either…
