I replaced it with the upgraded Bosch pump two years ago. I just noticed a lack of power going up a long steep hill after 1 1/2 hr drive at 70 -80 mph , felt like when the 003 pump was failing. Car set for a couple of hours than a little slower drive back with no issues.
I waited till this AM and hit the key in the on position and the pump was pretty noisy . I have isolated intercooler fluid blocking it from the engine coolant. Just wondering because of the always on mod.
Thanks for getting back to me.
