VW Transporter with hesitation and black smoke from exhaust

This vehicle was presented with a hesitation, lack of power under load and black smoke from the exhaust (No warning lights on).

Initial diagnostics showed a previously recorded turbo under-boost fault code.

A road test was carried out to confirm the customers complaint and further investigation was then carried out which included a visual and physical check of the air intake circuit, the latter using a specialised smoke leak detector to identify the exact cause of the issue – A cracked turbo intercooler!
