Driving my turbo 3.2 TT has always been a lot of fun. But one thing always kept coming back, almost to haunt me at night: The bolts that connect the turbo to the manifold were always coming loose.
At first, I thought: let’s find bolts that won’t get loose. Simple, no? I had the Audi S4 stainless steel “locking” bolts installed, to find out they broke 3 weeks later… My tuning guy decided to solder them in place. We both didn’t like the idea, but hey, I was really fed up. And I had a track day coming a few days later… You know what? After one day at the track, it still came off! The soldering didn’t work as it melted or broke off, not sure. But anyhow, I still had a problem.
My tuning guy came up with an idea, and I sure hope it’s the last time we go through this. He proposed the V-Band Clamp. So it was installed on December 23, 2010. Let’s see if it holds.

While I was on the spot, I took a few pics with my iPhone. Look at the 4th pic. There are interesting vehicles where I bing my car. In the background: a Porsche GT3 and an Audi RS4.

Lets hope that new bit stays on that DP as the heat will put some stress on those welds. Is your engine moving too much and that causes the bolts to come loose? Maybe stiffer engine mounts would help.
Story of my life 😦 Don’t have the problem now as down pipe is cast , when it was stainless it was a nightmare, Backdraft Kit at that time , nightmare 😦
