My wife has a 2005 c4 hatchback, it has started having a major issue local garage have had it for 3 weeks now and gave the car back without problem fixed. So my wife was driving it and the info screen came up with electrical circuit failure, then abs and then finally seatbelt/airbag, at which point the car stearing pulsed and then power stearing went. She stopped the car and then turned engine over ..... Nothing just a click ... Waited 15 mins car started no problem again 10 mins later same thing. The garage have changed the alternator, battery & bsi unit and the same issue, but if you take the battery off and fully charge it, it will work no problems until battery drains. When engine is off there is no drain at all when switched off. Has anyone had any similar issues and maybe know a solution...????
