WE87 - Checking Relays And Replacing Them If Necessary (Workshop Campaign)

Revision:

April 10, 2015
This revision amends WE87 as follows:
Under “Parts Info” the parts availability note was revised.

Model Year:

2015

Model Line:

Macan

Concerns:

Power supply relays

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is a
possibility that relays from a batch whose switching contact was not manufactured according
to specifications were installed on the affected vehicles.
As a result, the switching contact in the relay can stick in normal position and the relevant electrical
equipment will not therefore be supplied with current.
Depending on where the relay is used in the vehicle, this can cause various systems, e.g. rear window
heating or the levelling system, to stop working.

Action
Required:

Check the batch number of the relays and replace relays if necessary.

Affected
Vehicles:

The VIN(s) can be checked by using PIWIS Vehicle Information link to verify if the campaign affects the
vehicle. This campaign is scope specific to the VIN! Failure to verify in PIWIS may result in an improper
repair. This campaign affects 847 vehicles in North America.

Parts Info:

NOTE: PARTS FOR THIS CAMPAIGN WILL BE AUTOMATICALLY ALLOCATED FOR UP TO 50% OF
THE VEHICLES THAT ARE SERVICED AT YOUR DEALERSHIP. ONCE YOUR DEALERSHIP IS OUT
OF STOCK AND REQUIRES ADDITIONAL PARTS, YOU SHOULD SUBMIT A PTEC/PAV.
Part No.
