Hopefully they'll have a loan car Andy, but they've always been pretty scarce in the past unless the warranty work is booked well in advance. I can't call them till first thing tomorrow morning.

While I'm sure Revive won't hurt, if it's under warranty let JRA fix it. It'll be worth the wait.

Well, an interesting thing. Chief technician at Barbagallo Land Rover tells me the problem may not be the EGR valve, but a leaking hose. Don't know which hose yet, we'll find out tomorrow when the replacement hose is fitted.

So as it turns out, it WAS a leaking hose - the hose at the front of the engine, from the intercooler to the air intake on the inlet manifold - which manifested itself in the EGR valve fault. Apparently, nothing wrong with the EGR valve itself.
There's another problem though - a fault in the throttle linkage from the pedal.
Another night in the workshop, waiting for a spare part.

One of these?

Yep, that's the one...it wasn't split as such, there was a leak around the coupling. Apparently the same thing had occurred on another TDV8 in the same workshop, which manifested itself in the same EGR valve error reading, that's how the chief technician knew it might not be the valve as such.

So that's why cruise control was mostly OK but using the pedal wasn't. You've been unlucky to get 2 unrelated problems on the same outing.

I've seen a photo of a hose split across the hose along the clamp. Is that what happened?
