Hi,

My vehicle: Volkswagen Golf V TDI, 74 kW, BLS engine, 175,000 km.

The Golf only shakes when idling. Here are the values I obtained during the test of the idle speed control system:

Cylinder 1: +0.30 mg/H

Cylinder 2: -0.28 mg/H

Cylinder 3: -0.07 mg/H

Cylinder 4: -0.08 mg/H

Should only one PD element (cylinder 2) be replaced, or do three PD elements need to be replaced?

I appreciate your feedback.
