Hi sorry I’m new kinda here I have a 2.0 tfsi 2009 just brought it today drove it from London and I’ve got the engine light on 🤬 however it shows up as faults are 

 

16555/P0171/000369 – FUEL TRIM; BANK 1: SYSTEM TOO LEAN

 

16891/P0507/001287 – IDLE CONTROL SYSTEM RPM: HIGHER THAN EXPECTED.

 

My guess is the pcv valve and apparently can buy a delete kit for them is it easy enough to do ?

 

also I have cleaned the maf sensor but that all seems fine ?? Any advice will be great I plan on keeping the car seen as it was a new purchase today 

Air leak somewhere, take the pcv off and check for splits. Could also be a split hose

 

Nice 1 thanks for that I’ll try and take a look what’s best way to find a split hose ? Spray soapy water

Depends; some hiss if the engine will run, other need a manual inspection and not just a visual because there is no way to see right round them short of dismantling.

Just an update been using vcds this morning 

I can’t post the other fault as says pic is too big 

The other shows the other fault of the p0507 that was all
