Morning,
Can't hear anything hissing or wheazing, I've checked all I can.
I'm doing a service tomorrow so I'll have a good look when I get underneath.
I do have a bit of an update/theory.
I ran the car down below 1/4 tank the other day and it ran much better, it will still throw an error code, but you have to try a lot harder.
It got me thinking, I changed the fuel filter a few weeks ago as I thought that might be the issue, when I was done I put the ignition in position 3 to prime the system and heard nothing from the pump, thought nothing of it at the time but it's got me thinking now that maybe the in tank pump has gone, the injector pump is noisier on a full tank as well.
If the cylinder isnt getting the fuel it needs would that result in a drop in exhaust gas, lowering the pressure on the hot side of the turbo then in turn reducing boost or am I talking complete ©®@p
The wastegate does seem to be working as is the exhaust bypass.
Should the tank pump make a noise on every start?
Mine seems to be very silent
Sorry for the long post
