B5.5 lots of smoke poss no turbo

[tonyotoole1]

Hi all, I've recently had an issue with the IC Hose popping off, bought a new hose and clips and seemed to be fine although not 100%. Starting then getting a lack of power, like the turbo was intermittent. Today lost power on the motorway and loads of smoke coming out the rear!!! My initial thought is the Turbo could have seized, as I was a little low on oil (although the engine still runs sweet). As I limped home I then got an issue saying STOP MOTOR Oil Pressure!! I've given her more oil and the engine still sounds ok, but still smoking!

I will take off the Turbo and have a look. Has anyone else got another idea??

Thanks

Tony
