Hi All,
In case anybody's interested, here's the diagnosis from the garage:
"I did various pressure tests, but had frustrating results. Even with the car on the lift, the accessibility to the area of suspicion was almost nil . You can't see much of anything down there. So I had to use the force.
I think that the pressure pipe from the turbo was the main source of the leak, and I believe that this was due to a loose clip. Or, just not tight enough. It was probably ok for all this time, until one day it wasn't. So I have removed the pipe, cleaned and looked at it and put it back on - further this time, and with the clip as tight as I dare. Curiously, there were no fault codes to clear. I've driven it, and it seems fine.
When doing the pressure test, I did notice that the little connecting rod to the swirl flaps has popped off. I connected it, but it has come straight off again. This is a sign that your flaps have seized or one has cracked. It's a common thing, and unfortunately quite a job. There are many driving around in this state, but your economy and performance can be impaired. There is also a small air leak in this area (under the engine cover - just beneath the rocker cover near the oil filler)
Just putting it on your radar."
All seems fine for now, until next time!
Thanks,
Oscar.
