2018 Audi TT Service and Repair Manual

Trims covered

• Base

Known issues on the 2018 TT. One recall is on federal record for this model year, covering the fuel tank assembly: the tank can be damaged by the fuel tank heat shield bracket in a crash, and a damaged tank may leak fuel and raise the risk of fire. The factory diagnostic and repair procedures behind that system are here.

Whether you're inspecting the fuel tank and heat shield mounting or working through a routine service on the turbo four, it keeps you on the OEM procedure and correct specification for your specific 2018 TT.
