Used Audi / VW Coolant T-Piece Adapter, OEM part number 5Q0121087M. This genuine used part is a factory coolant pipe junction, also known as the T-piece or T-adapter. It was removed from a donor vehicle. This adapter connects coolant hoses in the engine bay, and a common failure is a brittle plastic joint that can crack or leak, causing coolant loss and potential overheating. Fits 1.8L and 2.0L turbocharged gas engines, including the EA888 2.0 TSI/TFSI and the 2.0L MHEV mild-hybrid variant.
