AUDI- ABG / AJK 2.7 BI-TURBO / 2.5 TDI ENGINE FOR SALE
AUDI- ABG / AJK 2.7 BI-TURBO / 2.5 TDI ENGINE FOR SALE, The Audi ABG and AJK 2.7L Bi-Turbo engines belong to the same family of 30-valve V6 engines. They were used in performance models during the late 1990s and early 2000s, with their main differences relating to the specific vehicle they were fitted to, which resulted in different power outputs. The “M” in the user query likely refers to a manual transmission, as these engines were offered with both manual and automatic transmissions.

Where to buy a replacement engine
Common issues and maintenance
The 2.7T is a robust engine but is known for a few common issues. Maintenance and parts costs can be high due to the engine’s tight packaging.
- Turbocharger failure: The stock K03 turbochargers are a known weak point. Because they are located deep within the engine bay, replacement is a labor-intensive job that often requires engine removal.
- Timing belt: The timing belt needs replacement at manufacturer-specified intervals. This also requires extensive disassembly of the engine’s front end.
- Oil and coolant leaks: After many years of service, seals and gaskets can wear out, leading to leaks. It is recommended to replace these during a major service, such as a timing belt or turbo replacement.
- EGT sensors: Exhaust Gas Temperature (EGT) sensors are a common point of failure and are expensive and difficult to replace. Many aftermarket tuning software programs can disable them to avoid faults.
