159 1.9 JTDm reving erratically
Hello, some good advice needed here.
My Alfa has just had its 60k (km, that is) service and apparently all was well. Took her to the road, and gradually a worrying problem started occurring: the rev counter goes mad everytime I need a push from the turbo (i.e., changing down the gear, pressing down the gas pedal in full), whether overtaking or working up a hill.
I can see the turbo is alive, because the pressure meter shoots as well, but while reving at 3-4k the car has no torque and is making a lot of noise (a diesel reving at 4k is not a pretty sound). I have to take the foot off the gas pedal, let it lev lower and slowly it picks up.
Took it to an Alfa garage and nothing comes up on the computer check (which brings me to the question: how good are these computer checks anyway?).
