Compressor shut off valve. It is the secondary turbo isolation valve.

the road between Old Andado Station to Mt Dare makes the road from Mt Dare to Dalhousie a German engineered highway. The bull dust was extremely deep and was wallow after wallow of dust holes. I hit one too fast with windows down. I looked across at my wife to apologise for her unimpressed face looking back at me. The dust went over the bonnet and up the wind screen like crossing a deep river does to water over the bonnet.

How can anyone not know about the boost hose issue on puma’s, it’s been so well documented and is generally pretty easy to temporarily repair boost leaks unless they’re at the IC or manifold.
No offence to anyone but if your gonna go and to trips like the Simpson desert and put yourself into remote areas you need to know a little about what your driving and have a few patch kits for various stuff.

Thanks for that. Not sure it was the boost hose issue that is so well documented. Might be. My skills and expertise are in other areas. But I'm told the hose replaced was an elbow and so maybe not one of the ones with the notorious issue?

I'm not a mechanic. A mechanic in a proper workshop and his helpers were unable to identify the problem during intermittent stuffing around over a 24 hour period ("its boosting okay"; "I can't see any tears or holes..." etc) before telling me to see if the RACQ would tow it home, so I don't know I'd be any better in the middle of the desert with the best tool kit and spare part collection going.

It really is bit much if the Defender is so unreliable that you have to skill yourself up to diagnose and fix problems that can't be worked out by someone who earns there living as a mechanic.

Without being too defensive: the French line in the Simpson Desert is relatively busy and we knew that to be case before heading off. I also had insurance to cover up to $30,000 for off-road recovery in the event of a mechanical breakdown that required assistance, the vehicle had just had its major 80,000 service, and I had basic tools and rescue tape.

But sure, I'd like to learn a bit more about what I'm driving - you offering?

Eventually after many hours of climbing dunes extremely slowly, we were on the flat into Birdsville when the error codes appeared. Took it to the mechanic as we could see nothing obvious. Neither could the three of them, in consultation with an LR specialist in Brisbane. Flatbed home for the D4 and flights for us. Turned out to be a seized CSO valve.

How'd you get up those dunes in limp mode? Must have been a challenge!

What's a IID tool? Is that the same as the Nanacom?

Is it possible to clear the fault by locking and unlocking five times?

Trouble is, where do you start and where do you stop!
So far on mine (2015 M.Y Puma), Ive had a replacement clutch, replacement rear Diff, output shaft, aircon condensor/thermostat.
Whilst I've always fixed and serviced the vehicles i own(including a Series II, this Defender has been the most unreliable,...............all of these issues with a new car!

Don't get me wrong , I absolutely love the vehicle and how capable it is but when 'she who must be obeyed' wonders if it'll break down again on the next trip ,..........lets just say a trend is emerging!!!

Sounds like you did everything reasonable to prepare for the trip.

It was an eye opener as to how slow you can go up them. It was a challenge with a couple being driven twice to take a different line as we just ran out of go. Speed was as low as 1kph on the top of some dunes. We just needed one snatch at the top of little red as it was so chopped up. The GAP IID tool is like a nanocom .

They must have been pretty useless mechanics.
