u/Ill-Marsupial-1440

I have a Stage 2 (034) 2018 B9 S4. Unfortunately in the last week the charge pipe has started to come loose at the drivers side. I have an upgraded intercooler, but the pipe is coming loose further up where 2 OEM sections are connected by a Jubilee clip.

It's really hard to access that clip and even when I struggle and seem to have tightened it it comes off at high boost pressure anyway.

Has anyone had a similar problem and might have some advice? Should I be trying to access this from under the car? Currently I am removing the air filter housing and reaching in from the top of the engine bay.
