Help ASAP

[tombaxter11]

Hope someone can help and/or give me some advice. My car is a 05 gt tdi 140 that is remapped to about 180ish.

Anyway I bought this car a few months back and it always had a slight boost leak but never got around to looking at it until the other day. It was the elbow that comes off the turbo outlet, it had a massive slice in it. So I got the part and replaced it. Them damb clips are a right pain to get on. Anyhow I got them on and took the car down the road. Never felt it pull so well. Actually took me back. But within a minute I heard a pop and had no power. Knew exactly what had happened. The pipe had popped off.

So today I have been back under the car and fixed it with the old tie wraps and jubilee clips. Pretty sure that will never come off now!

So took the car down the road again. Moved like a train until maybe half a mile when I heard a similar pop again. But this time time it is different. It's down on power again but the engine is really loud like there is no air filter or the exhaust as come off. I've had a look and can't see anything. The elbow definitely hasn't come off tho.

I'm worried because the car hasn't seen this much boost in a while that now something else has popped. But why the loud noise?

If anyone has any ideas it would be really helpful. I would love to get the car working to full power. At the minute it's like a straight diesel bit you can hear the turbo, just over the loud engine.

Thanks in advance!

Hey, I would suggest that you back track from the charge air outlet off the turbo all the way to inlet manifold and make sure every pipe and connection is solid. After that I would suggest you pick up a smoke tester, these plug into your intake system with a rubber bung and push “safe” smoke into all the pipes this way you can see 100% if you have a boost leak by means of a damaged/torn pipe.

I doubt the engine would have taken the hit it sounds more like giving the car more boost after a long time has caused some damage to the intake system
