Car is a MK6 GTI 2010 Totally Stock
So I had posted previously regarding some chain noise around 2.5k rpm and off throttle when the car has warmed up. I had taken it to a couple of garages and they suspected either the Timing Chain or Intake Camshaft VVT.
So I decided to do it all myself and I'm looking for more options as the noise is still present after
I have changed
Intake Camshaft
Timing Chain
Tensioner
Cam Bridge
Cam Sensor
Cam Adjustment Actuator
Cam Adjustment Valve
Car runs perfect until its warm and the VVT coming into play. I have had it on a scanner and it seems the VVT can't change properly to advance/retard the timing.
As the VVT is all controlled by oil pressure, the only think I can think of is if the oil pickup is blocked and the oil gets warm its struggling to pickup enough to pressurise the VVT.
Does this sound plausible?
Other than that any other ideas?
I'll see if I can post some video of the noise.
