Renault Laguna III - 2.0dCI Sport Tourer Owner's Review - Alanovich
Well well well. On closer inspection, it's not the hose/clip that's leaking. It's the water pump. The garage manager says this can happen sometimes when fresh coolant is introduced, causing the seals to leak. Is that so? New one on me, but there you go.
The vehicle's under RAC Warranty, so hopefully they'll cough up. £150 quote to fix.
