Ok I have a 2011 1.6 htp and have the fault code po299. The car belongs to a friend who took it to a local garage who did a diagnostic test and said it was the boost pressure sensor which they replaced. My friend then collected his car and within a day eml light on again and same symptoms, so now he has bought it to me and I got the po299 code come up saying turbo charger low boost pressure. Can anyone give me some advice as where to start looking as don't want to just chuck parts on randomly and wasting his cash. Thanks to all in advance
