Actually - it is both last Friday and last night /Thursday 21:25. That's because you had always saved the logs into same file - no worries! VCDS just appends new logs into the same old log file.Nope I’ve done these wrong again havent I….. and the 2nd lot are from last Friday , not tonight.
Yes, VCDS could be better - possibly. On the other hand, VCDS simply does it's job - without too many question asked - so it's a kind of powerful and quick when you get used to it.how it saves the files, where it saves the files etc..... when i close a log it doesnt ask me where i want to store it or what i want to call it...
i have so far,
tested the vacum to n75 - 25mmhg
tested the vaccum line to turbo - it holds at 20mmhg
replaced the N75 valve
inspected all vac hoses, which seem fine.
looked that the waste gate actuator, it seems to move freely on vac but does have just a tiny amount of "play" in the linkage when closed. (suspect)
looked at egr valve, its clear and the valve itself functions on demand
looked at the egr inlet and oulet hoses, i replaced them and the gaskets both ends.
looked at intercooler hoses, all good, clean inside.
Based on the reported values on the log not an issue. Pressure across the DPF seems to perfectly normal, well actually too good - about 6 hPa on hot DPF engine ticking over. Still a leak in exhaust?Could
It be back pressure of exhaust gas from a mucky dpf?
A leak before turbo would explain the lack of boost.Do you think it’s possible I have a crack in exhaust manifold ?
It’s much better than it was but I still get eye stinging exhaust stink from back of the engine.
I also did whitness a tiny amount of smoke come from the turbo , it was from the centre of it where the two halves meet and the actuator rod sits. A tiny puff when revved.
I would say both of them. Anywhere in the exhaust flow before the turbo has taken advantage of the exhaust flow energy to create boost on intake side.When you say a leak before the turbo, do you mean the exhaust manifold or the middle of the turbo where I saw a whisp of smoke come from a few times?
How about someone blocking tailpipe when engine ticking over?How can I test :
Exhaust manifold (for crack)
Smoke leak tester?Inlet manifold (for crack)
Charge air intercooler (for blockage or failure)
