VANOS Solenoids have failed me before - I knew there was a problem with them. I would normally have to restart the car on the side of the road to restore power. Did this on a trip back from NC.
Recently, VANOS failed on Highway while boosting. Went Limp mode. Restarted car. This time had significant power loss, outside of limp mode.
VANOS solenoids replaced. Codes have not come back.
From 1000-3000 (Before turbos kick in) there is a significant lack of power. I have to push the pedal down a decent amount to notice acceleration.
I had someone plug ODB in and drive the car. They noticed a fuel pressure problem.
I have smelled fuel twice leaving 1st gear today.
Could it be the VANOS system itself? I hear symptoms are similar to what Im describing, bad MPG, lower power in lower range RPM..
Or should I focus directly on the fuel system?
Please man, any advice.. I am dying over here.
