17545 - long term fuel trim add. Fuel. Bank 1 system too rich
17705 - connection turbo charger throttle valve
16795 - secondary air injection system b2 incorrect flow
16186
Also an srs code00532- supply voltage b+
Am i right in thinking the first two are both related?
I do have a dodgy thermostat, (not getting upto temp unless staionary)
Any ideas on things to look for?
Do have a split breather hose,

I'd advise sorting thermostat first mate, can affect the amount of boost, (cold start mode=less boost (sometimes)
I also once saw a post about coolant temp sensor reaction times causing 17705.

I agree though, 17705, means its leaking somewhere (normally)
-
And the trim/ rich related one might be where it's loosing boost, (air) so excess fuel makes it rich, the trim is where ecu tries to correct the running conditions, from what I was told.

Have you had the recirc valve/dv replaced at all?
Also, where is your split breather?
Breathers, boost and vacuum lines can all cause 17705, depending where they are.

(I have 17705 (still) :( an also had a fuel trim/rich code before, amongst others)
