Help - black smoke and power loss

Hi
I am new to defenders - have a 2008 90 Puma engine. Had it one week - it’s under a 3 month warranty so back at the garage. Was fine but then started to sound like it was grinding and slowing - no power and black smoke. Was at high speeds but now also at lower. Hopefully garage will sort it but it would help if I had an idea what to expect and what I could do myself in the future? It’s got 60,000 on the clock and I love it to bits but is this a common problem????
Also new to this site - so Hi!

Black smoke is caused by to much fuel or to little air getting in the engine.

Collapsed turbo hose

Split in the hose between the turbo and intercooler is a known problem on pumas. The 90 degree bend off the outlet from the turbo splits because the steering shaft knuckle joint rubs on it. A dealer replacement for a modified hose component is required, done under a recall. This might have been done by previous owner however, so you might need to look elsewhere in the air system between the turbo, intercooler and inlet to the engine.

Thanks for the posts - I’m new and learning
Cheers
