i was on the way home and i put my foot down, i heard a big bang/pop. this was followed by black smoke and no power. i was only 15 seconds from home so when i got there i looked under the bonnet. the intercooler pipe had come off. i re-fit it and took the car out again and it seemed fine, but as i re-fit the pipe i noticed oil inside it. does this mean my turbo is on its way out?
