just my luck im about to order another doblo in the next few days and was hoping to trade my 200000 mile old one in,on my way home tonight I noticed my taxi computer set had stopped responding then suddenly the abs warning light came on followed by the air bag failure see handbook message,the battery light then came on,i switched the engine off on a hill but it wouldn,t start,it bump started ok so I headed home,just around from my house a message reading (ebd failure switch off engine appeared)this is a new one to me,just as I was parking up the headlights and interior lights all began to dim and die, my battery is only 3 years old and was an expensive one ,any ideas
