I was concerned about a cracked manifold.....perhaps the smaller leaks were so obvious that it might need another smoke test to confirm there are no further issues.
Anyway, it’s back with him....watch this space"Better to remain silent and be thought a fool,than to speak out and remove all doubt" ?.....what rubbish...

Usually when the wife is driving....so under hard acceleration/load
Doesn’t do it to me on cold start, but does on warm/hot start...."Better to remain silent and be thought a fool,than to speak out and remove all doubt" ?.....what rubbish...

Thats the next question, is it actually restricting power, and what fault codes are stored?My D3 Build Thread

For a couple of months now, I’ve had the dreaded “Restricted Performance” warning come up intermittently, followed by, erm, restricted performance.
I had the fault code read, and feared the worst (P1247-00 Turbocharger boost pressure low)
Only making short local journeys at the moment, I’ve largely been able to drive round the issue, but overtaking a tractor yesterday, the sudden and unexpected lack of grunt on a country road became dangerous.

Thanks all.....yes, switching it off and on again seems to sometimes clear it, but not always......I did pass on the message about it potentially being the manifold so let’s wait and see"Better to remain silent and be thought a fool,than to speak out and remove all doubt" ?.....what rubbish...

Yes but think about it, there is no time in any one cylinder that an inlet valve is open, at the same time as an exhaust valve.
It’s like one of those water flow puzzles you see on Facebook! Took me a while to get it.
'Modern' engines still have valve overlap don't they to scavenge exhaust gases?

I had a similar issue with our “old” MY2010 car. It only did it when towing the caravan and accelerating. If I stopped, closed the car and left it for 30 seconds it always cleared, but it was heart in mouth time every time we put the caravan on. It turned out to be something on the secondary turbo (actuator? - it’s a few years ago now!), which made sense as I got the message and lack of performance just about at the point where the secondary turbo would be kicking in (2,800 - 3,000 rpm ISTR).
