Service bulletins for the 2012 Volkswagen Touareg

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

V011231 20235912019-04-08. Service bulletin. ENGINE AND ENGINE COOLING; EQUIPMENT ADAPTIVE/MOBILITY. Technical Bulletin (TDI Clean Diesel I/M (Inspection Maintenance) Testing Issues due to Readiness Not Set): Some readiness codes on TDI clean diesel vehicles require special driving conditions to be set. If DTCs have been recently erased from the vehicle?s ECM, it may take additional driving under different conditions to fully set OBD readiness parameters. MVB 89 (on non-UDS protocol ECM?s) will store correct data concerning OBD readiness. This document illustrates how to manually read OBD readiness codes.
TT 20-13-042019-04-08. Service bulletin. ENGINE AND ENGINE COOLING. Tech Tips (3.6L ? MIL ON with DTCs P2400, P2404): This document informs for concerns of MIL ON and P2400/P2404. This can be caused by the change over valve on the water pump. The water pump has a vacuum controlled servo to control the flow of coolant. If the diaphragm fails, coolant can get into the vacuum supply line for the LDP pump. Vacuum test the port on the water pump. If it will not hold vacuum, replace the water pump and the vacuum supply line as necessary and retest operation.
