what happens when the turbo goes on a diesel

Oh, interesting topic. Yes, when the turbo fails on a diesel engine, it can cause a variety of issues. For instance, a decrease in power output or an increase in fuel consumption due to the turbo's role in increasing the efficiency of the engine.

Typically, you might experience slower acceleration, burning more fuel than usual, or hear a whining sound from the engine. In some cases, there can also be excessive exhaust smoke as a result of engine oil leakage into the exhaust system. This happens when the bearings of the turbocharger wear out and allow engine oil to seep in.

It's vital to consult with a professional car mechanic immediately and avoid driving the vehicle further to prevent potential engine damage. Regular maintenance checks and following the car's servicing schedule can also help prevent such issues.
