Service bulletin V801503 2040580

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.

NHTSA's summary

Technical Bulletin (No Heat from Passenger Side Cabin ? Heater Core Restricted): Excess flux from the aluminum cooling system components (EA189 TDI engine CKRA) contaminates the cooling system. This over time causes a high acidic concentration in the coolant. The result is oxide particles (aluminum rust) and excess flux restricting the heater core. This document contains information on how to diagnose, and service this issue.

Listing a model year does not mean every vehicle of it is concerned: the document says which.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
