BMW 535d Hybrid turbos valve spring+ M57 sound check

Welcome back Another Bmw 535d this time stage 3 with hybrid turbos running just over 400bhp, very clean and well maintained example, customer requested to use all Genuine parts so we did. As you can see from test drive part of the video, smokeless before and after Valve spring upgrade, it just shows if you maintain these cars they run well and for ever. If you got any questions in regards to this upgrade or any other work feel free to contact me. Thank you for watching and your support!
