Summary
Technical Bulletin (TDI Common Rail High Pitch Whine Noise after Switching Ignition OFF): With the implementation of the new ?Clean Diesel Technology?, changes to the EGR system were implemented as compared to previous Diesel engines. After switching ignition OFF, the EGR system must go through an adaption of the valves to maintain calibration. These noises are considered normal and no repairs are necessary.
