Hi, I drive an Audi A3 2.0 TDI 2005 8P. I recently got the car remapped to stage 1 and since then whenever I would drive the car revving it past 3000rpm the turbo pipe would blow off. It has happened 3 times now after today. After the second time I was fine driving under 3000rpm but the turbo pipe just blew off today when I stupidly decided to launch the car. I know I can just buy a new turbo pipe and replace it but is there any way anyone knows of to secure the pipe more or make it stronger? Or if there’s a different type of turbo pipe or something else in general? Sorry if this all sounds really stupid but I don’t know much and would like some advice on this issue. Separate to this issue my car also always goes into limp mode when driving. Normally it happens at around 5th gear 70mph or 6th gear 80mph. If anyone knows of anything I could do to fix this issue I would appreciate the advice. The car has a really nice growl sound now since the turbo pipe blew off. The last times the pipe went off the car wouldn’t have this growl sound so that might be a different issue but I’m not sure. But is there any way I can fix the car and keep this nice growl? 😂 Any advice works, thanks for any replies. https://www.ebay.co.uk/itm/264302673044?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=1prSY_qCSXy&sssrc=2349624&ssuid=&var=&widget_ver=artemis&media=COPY ^^^ Thats the pipe that’s come off. It’s on the left hand side of the car.
