Why VAG Engines Experience Oil Pressure Problems?
Certain VAG engines, including some 3.0 TDI models, have been reported to have issues related to oil pressure regulation at lower RPMs. This can be linked to the Pulse Width Modulation (PWM) controlled oil pressure regulating valve used with specific ECUs like Bosch MD1CP004, EDC17CP54, and MD1CP014. The design is sometimes cited as a factor in meeting emissions standards.
