Car Fix DIY Videos

The factory air suspension works well… until you start asking more of it.

In this video, I’m installing the TGK Motorsport Air Tank Upgrade on my Audi S7 to increase the air reserve available to the suspension system. A larger air tank can help the suspension react more quickly, reduce compressor cycling, and provide more consistent performance during repeated height adjustments.

I’ll walk you through the entire installation step-by-step, point out a few helpful tips, and show you everything you need to know if you’re planning to install one on your own 4.0T Audi.

In this video:
• TGK Motorsport Air Tank installation
• Removing the factory components
• Air line routing
• Mounting the new tank
• Leak checks
• Final results

This upgrade is compatible with many Audi models equipped with factory air suspension, including the S6, S7, RS7, A8, and others. Be sure to verify compatibility with your specific vehicle before purchasing.
