So had some drama, was driving around and all was well, slowed down to a stop street. Pulled off and only made wastegate pressure, also noticed a fair bit of rattling from the engine. So drove home slowly.
Checked for faults and found these - WTF!

17965 - Boost pressure regulation valve (N75) Open Circuit

17938 - Camshaft Timing Adjustment: Short to Ground

17697 - Boost Pressure Control Valve (N249): Short to Ground

Had a look under the bonnet and couldn't see anything damaged or disconnected. Found it hard to believe all 3 components failed at the same time.

So did a quick search on google and found a post on a TT forum, someone said to check the #34 fuse as its the fuse that protects those 3 circuits.
And presto, fuse was blown.
New fuse replaced and crisis avoided
