Hi, new to the site today.
I bought my S60 D5, 03 plate with high mileage of 193k but loads of history and all motorway miles. ( Private, sold as seen ) , drove lovely on test drive and to work and back for two days, then this morning within a mile of home under normal acceleration I heard a loud pop / bang and black smoke pouring out of the exhaust followed by the car chugging / jumping / misfiring etc. I pulled in and stopped engine then restarted, it ticked over and revved fine, so pulled away again but had loads of black smoke and the rough engine again, so limped it back home. not sure where to start, I thought Turbo but when I explained to a friend, he immediately said an Injector had gone.
Has anyone had the same scenario or have any idea's as to where I can start getting to bottom of this, garage or main dealer is not a financial option.
My mate is popping round when he finishes work with his snap on diagnostic machine but just trying to get a start....
Any help advice would be greatly appreciated....... Regards ... Ant
