Genuinely think my heads been up my arse the past 2 weeks.... So had some peace and quiet to have a good look around, noticed the hose that goes straight into the turbo has a huge cut on it, couldn't see unless I looked at the hose that runs over it was covering it partly. You know the hose that's like on the right of the oil dipstick is that the intercooler hose? (goes straight into the turbo).
