Burst hose after intercooler on turbo diesel

Losing boost, still drives, just low on power. 3 hours from home. Will I damage it driving it, keeping it off boost?

Back on the right side of the channel now! Peugeot Expert van, 1.9hdi.
Had it off and cleaned it up. Petrol station "black cloth tape" seems to be holding up. Drives like normal. ETA home, 2.30 pending further setbacks.
