On Audi/VW applications, 17964 / P1556 is defined as “Charge Pressure Control: Negative Deviation.” In plain English, the ECU requested more boost than the turbo system actually delivered. Ross-Tech lists the main symptoms as reduced power output and limp mode. Possible causes include boost pressure too low, hoses/pipes incorrectly connected, disconnected or leaking, charge pressure control defective, turbocharger defective, wastegate/regulating valve problems, and on some applications MAF-related issues.
