Technical Service Bulletin
Technical Background
Under certain driving conditions, the linkage for the waste gate actuation can encounter excessive wear which
leads to play at the waste gate flap. This leads to boost escaping through a loose flap, which sets DTC P029900
(Negative Pressure Deviation).
Production Solution
Not applicable.
Service
1. Before beginning service:
• Address all other conditions, such as leaks/blockage in the intake system or additional DTCs
• For sporadic, single occurrences of DTC P029900 (Negative Pressure Deviation), delete the DTC and
check if it reappears during road test.
• If DTC P023400 (Positive Pressure Deviation) is present, review TSB 2027082.
• After addressing these other conditions, check to see if the conditions listed in the Condition section of this
TSB still apply. If the conditions do not apply, this bulletin does not apply.
• Do not replace turbo unless instructed to do so by GFF.
• Claims are subject to review or audit by Audi Warranty. Repairs performed when all conditions do not
apply will not be reimbursed.
• Verify the condition by confirming that DTC
P029900 is stored in in the ECM, and that the
wastegate link plate has visible play in the
direction of the actuating rod (Figure 1). Review
the attached video clip for an example.
