Critical Installation Requirements

The VW 2.5 TDI engine is sensitive to lubrication; please follow these steps to protect your investment:

1. Correct Oil Specification: Mandatory. Use only high-quality synthetic oil meeting VW 506.01 (or 507.00 if the vehicle has been converted/updated) specifications.
2. Prime the Turbo: Before the first engine start, fill the turbo's oil inlet port with clean oil and manually rotate the compressor wheel to ensure the bearings are lubricated.
3. Inspect Exhaust Manifold: T5 2.5 TDI engines are prone to warped or cracked exhaust manifolds. Ensure the manifold surface is flat before mounting to prevent exhaust leaks that can damage the new turbo.
4. Oil Feed Pipe: Check the oil supply line for carbon buildup. Replacing this pipe is highly recommended to ensure constant lubrication.
