s60 Loud pop / bang then black smoke and chugging/misfiring

slappinbass · May 11th, 2016, 13:02

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

Check the intercooler to turbo pipework carefully. Sounds like a split feed pipe into the turbo = no power & lots of black smoke.

Right, the inercooler pipe on right hand side as we face the front of the car had blown off, so I fixed it back in place, tightened it up and test drove the car.
Within 1/2 a mile it blew off again.
Any ideas ?????

Blown/clogged intercooler maybe?
Have a look underneath for a bowed bottom or oozing fins.

There are many D5 maintenance videos in my signature which are worth you looking through.
You may be suffering from huge overboost which can be caused by a sticking boost solenoid near the starter motor or stuck VNT vanes so if you have a vacuum tester, get that on the VNT actuator.

Take your mate for a drive with live data running on his snap on and get map readings at engine off, ignition on and out on the road.

Thanks cheshired5.
the car is hardly driveable once pipe blows off but will give it a go, will certainly take a look at the vids, and check out all you have suggested, many thanks and will post updates as I work through it....Cheers .. Ant
