Our Recommendation
Our Recommendation
For the 3.0 TDI, if the issue is purely an oil cooler leak, a specialist seal replacement is the most cost-effective first step. However, if the engine has suffered oil starvation, a rebuilt unit is required. For the 3.0 TFSI, a rebuilt engine assembly with an updated supercharger coupler and revised cooling components is the most reliable long-term solution to restore factory performance.
