simprez: nie zrozumiales
951 posiadaja pompe wody dla turbo ktora zalacza sie po wylaczeniu silnika i pompuje wode do turbinyprzez 30 sek - i tak wlasnie powinna dzialac - odpowiadajac na zadane pytanie.
"I hear a humming noise under the hood after I turn the ignition off. Is that normal?
The noise you hear is the turbocharger cooling pump. You should hear it run every time you turn the ignition off. The pump also works off a temperature sensor mounted in the turbo cooling water outlet line. However, the pump relay has a timer which will run the pump for 30 seconds after the car has been turned off regardless of temperature."
Nie wiem czemu u ciebie dziala w odstepach, ale zapytaj gerta, moze wsadzil tam jakas inna elektronike sterujaca?
