renault scenic megane?

open the bonnet and remove the plate covering the exhaust outlet.
while the engine is running check the joint for leakage.
if its leaking get an exhaust sealant, let the exhaust cool down before you attempt repair. undo the 2 nuts n bolts and smear the compound around the pipe put lots on, refasten it. check its no longer leaking before replacing the cover plate.
