Well some developments.
Definitely not DPF, as no warnings on the dash as snapdragon indicated.
I swapped the actuators for the inlet manifolds around from right to left to see if that moved the issue to the other side (thus pointing to a dodgy actuator) but that didn't do anything. The problem of the falling actuator happened still on the same side.
Took off all the ducting and pipes, and looked inside the manifold to see if the flaps were freely opening and closing when I manually moved the actuator - which they did.
It appears that the car is trying and failing for some reason to move the actuator on that one side, and instead defaults to leaving the manifold flaps open.
Again not sure if this is the issue or not -as the engine runs smooth still, and it should be turbo-ing up when I run it still. However that is not the case.
I also took off the turbo and had a look inside, its moving freely and is super clean. The actuator is also free to move around on there.
So basically, here I am - with not a clue in the world of what it could be though I know its going to be some small gremlin.
The real problem is this - I have agreed to part ex this car (before the turbo fault) for a new car. They gave me a low trade in value but I was happy as I was so excited to change car.
Now the issue is quite simple - I doubt they're going to take the car like this... and I don't have the px value they offered to me available in cash to continue the deal with them without the traded-in A8.
So I'm stuck... any ideas people? Or anyone want a bargain A8 if they know how to fix this issue?!
