T4,G3 Turbo Oil Return Pipe - 1.9 Turbo Diesel (ABL)

Replacement oil return pipe for turbocharged VW 1.9 Diesel engines. This pipe carries oil back from the turbocharger to the engine sump (backflow), allowing the turbo to lubricate correctly without pressure build-up. A blocked, damaged, or leaking return pipe can quickly lead to turbo oil leaks or failure, so replacement during turbo work is strongly recommended.

Designed as a direct replacement with correct routing and fittings for the listed applications.
