Tool to use:
I use PP2000 Peugeot diagnostic tool to read out codes, I bought from obdtoolshop.co.uk

P0170 - Fuel Trim Bank 1
P0011 - A Camshaft Position - Timing Over-Advanced or System Performance Bank 1
P0012 - A Camshaft Position - Timing Over-Advanced or System Performance Bank 1
Advice:
I think you should remove the vvt solenoid, easy enough to do and just give it a good clean and tell us what the condition is like before you clean it
Solved:
It was a faulty Pre-cat Lambda.
Fuel Trim Bank 1 = Pre-cat Lambda sensor
