Dear Volkswagen Owner:
As a valued Volkswagen customer, your satisfaction is our utmost priority. We are writing to you today about how we
intend to address/prevent some potential emissions-related issues that some customers have experienced in certain
2009-2012 MY Volkswagen Touareg 3.0L TDI vehicles.
What is the issue?
•
In some vehicles, corrosion can form in the differential pressure sensor, causing
the Malfunction Indicator Light (MIL) to come on.
•
In some vehicles under certain driving conditions, the MIL may come on due to
an issue with the Engine Control Module (ECM) software.
If the MIL is on because of either issue, your vehicle will not pass an IM (emissions)
inspection. Please note that your vehicle may be subject to one or both of these
issues.
What will we do?
As needed, your authorized Volkswagen dealer will install updated Engine Control
Module (ECM) software and/or a new differential pressure sensor on your vehicle at
no cost to you. This work can take up to two hours to complete.
What should you do?
In order to limit any possible inconvenience, please contact your authorized
Volkswagen dealer as soon as possible to schedule your repair. This will allow your
dealer time to plan ahead and ensure that the required parts (if needed) are available
for your vehicle on your scheduled appointment date.
IMPORTANT!

otherwise modified from original factory specifications with aftermarket
components and/or software, work needed to repair, replace, or return the ECM to
original factory specifications is NOT covered under this action.
