Technical Service Bulletin 26 Refill AdBlue warning comes on prematurely with no faults stored 26 16 28 2038295/3 June 15, 2016. Supersedes Technical Service Bulletin Group 26 number 15-26 dated November 17, 2015 for reasons listed below. Model(s) Year VIN Range Vehicle-Specific Equipment Q7 2009 - 2015 All TDI engine Condition REVISION HISTORY Revision Date Purpose 3 - Revised Warranty (Added max time for GFF) 2 11/17/2015 Revised header data (Added model year 2013 - 2015 Q7 TDI) Revised Service (Added Tip with video link) Revised Required Parts and Tools (Updated part number) 1 9/16/2014 Initial publication • There are “Refill AdBlue” warnings in the cluster. The warnings appear approximately 1,500 - 2,500 miles after the last top-off. • When the AdBlue tank is refilled, the vehicle will only accept approximately 1 - 2 gallons of reductant. When checked manually, the active tank is 50% full or less and the passive tank is full. • There are no reductant system fault codes stored. If any reductant system fault codes are stored, this TSB does not apply. Technical Background The reducing agent transfer pump V436 may be faulty. The vehicle cannot pump AdBlue from the passive tank to the active tank. Cars in hot weather regions are more prone to this issue. Production Solution An improved transfer pump is available. © 2016 Audi of America, Inc. Page 1 of 4 All rights reserved.
