Open the stop valve of the pressure gauge by pushing towards the pressure gauge. Measure boost pressure at full engine load:
- at the stand: in third gear at a crankshaft speed of 4000 rpm;
- when the car is moving: in 2nd gear, at the same time braking the car to maintain a speed of about 60 km / h.
If the boost pressure is below normal, the turbocharger must be replaced. If the boost pressure is too high, check the tightness of the boost pressure control valve connections; if the valve is defective, replace the turbocharger.
