P0046 Fault Code

While accelerating, got up to about 60 (noticed some smoke at the back) and car goes into limp with a message on the dash (though I missed what it said the first time, second time I was ready engine fault).

Did a fault read on the nanocom and showing P0046, I'm suspecting Turbo boost hose?

Whats the consensus?

Well after cleaning the MAF and MAP checking everything I could get access to, I spotted a 2 split in the turbo hose....Ahh that will be the cause then...

Quick trip to the dealer and £42 lighter, and I have a job to do tonight Thumbs Up
