It's strange that it's putting it into limp home mode, but not storing any fault codes, as it must be detecting something to make it go into protection mode.

Are there any big holes in the exhaust or anything?

That's nothing compared to my old lump, and that seems more white mine used to be thick blue / dark blue smoke.

Does it really cover the car behind it, hard to see in the vid and what revs did you take it up to and was the engine cold when you took that video.

revved upto 4000rpm,but was in limp mode at the time.
definitely not blue smoke and engine was cold-ish,hopefully the new CTS will sort it *prays*
