my 306 cabriolet got a really annoying problem.every so often just cuts out. its ok for like 3 months no problems then will just start suddenly cuts out for no reason and the rev counter goes up and down with hitting the accelerator. if l stop and wait for it to get cold then re start its absolutely fine. |Also ive noticed it much worse at nights when lights are on etc. Bought a new Battery but makes no difference at all. Any ideas ?

uhh . no

go to garage and ask for relay 109 to be replaced

hope it does it

no sorry

check if air con is on also check air filter to engine
