New owner, p1297, p0101,p2188

Hi guys, I'm a new owner of a 2007 gti.  I am having p1297, p0101 and p2188.  The main issue is the p1297 which is constant and the other errors come up after driving hard for a long time.  Car has power, but not much in lower rpm.  Diverter valve removed and checked, no broken diaphragm.  What I then noticed is a very strong vacuum when removing oil cap. Any ideas please as I am used to tdis not petrol.  Boost pipes seem ok, no visible oil leak from there.

I had a persistant vac leak turned out to brake boost pipe from vac pump to boost valve to crankcase new pipe £33 fixed hope tis helps

I had a slight hole in pipe that didn’t show till on full boost.....new black rubber sorted the problem

Have you had a look at the PCV valve?

Thanks guys for trying to help. What should I look for in the pcv? How do you detect vacuum leaks and or boost leaks?

try unscrewing your oil cap engine running if it gets sucked from your grasp probable pcv
