The odometer should be accurate for the standard tyre size whereas fuel consumption might be accurate for a specific controlled test but tends to be optimistic with normal use. I noted that LR's published 3.0 D4 consumption figures were for a vehicle fitted with 235/70-17 tyres, which can't be fitted to normal production 3.0 vehicles.

Whyatt's Land Rover ? Welcome - Land Rover Repairs, Service, Parts in Geraldton WA

That's good to know, thanks for that Andrew. I'll see what happens when we get back to the mainland on Friday.

It sounds like a sticky primary turbo actuator.

So it turns out to be a mafunctioning EGR valve causing the power loss and engine systems warning. Thanks to Andrew for recommending Whyatts Land Rover in Geraldton, who were excellent in their service. They ran their SDD Land Rover computer over the car and immediately identified some fault codes, including the EGR valve and - annoyingly on such a long trip - the cruise control, which failed as soon as we left Denham this morning.

We were able to cruise at normal speed until we hit hills or needed to overtake, at which point the car just didn't have the grunt to do the job properly. Glad we weren't towing anything.

Unfortunately Whyatts weren't able to replace or repair the EGR valve on the spot (it's a big-ish job, even if they had the part, which they didn't). So we've got to limp back to Perth (400-odd kays) tomorrow morning but at least we know the issue and it can be fixed under warranty soon enough.

For those who live in WA, or are planning to visit, it's worth noting that Whyatts are the only authorised Land Rover technicians between Perth and Broome. Bloody long way between drinks if you get into trouble.

Thanks to all Aulroians for your input:-)

It appears that the 4.4 TDV8 only has 1 EGR valve costing around 300 GBP whereas the 3.0 TDV6 has 2 each costing around 400 GBP - good for when these engines get older.

Is the CC fault caused by a faulty brake light switch?

Don't know Graeme, Whyatts printed out a copy of the fault report to take to Barbagallos in Perth, they think it might be something to do with a faulty switch in the accelerator pedal. While the EGR fault was 100%, the CC fault was only at 18%. Somehow the two are connected, no sure how.

Interesting to note that when the cruise control was working, there didn't seem to be a problem with the turbo function. For example, if I wanted to accelerate to overtake a truck, and used the throttle pedal, the car would struggle to build power. But when I used the cruise control plus button, it would respond with instant increased power.

Eventually though, the CC refused to co-operate altogether ("Cruise Control Unavailable"). Very disconcerting to have almost no power to accelerate from traffic lights or to pick a gap in the traffic.

Perhaps the CC fault is simply due to the EGR fault.

Yeah I think so Graeme. Just got back to Perth, engine system fault warning on all the way. The guys in Geraldton reckon it's a new EGR valve, maybe $2,000 worth including labour. Will be going into the dealer asap next week. Thankfully, still under warranty.
