Hi it's a 2004 I have checked for water under the bonnet and in the boot nothing I can see, I have changed the battery and the alternator but the problem is still there, I have had an Auto electrician out but he said he could not get into the brain so I don't know where to go next ?

Answer 1

Thermostat code and just having a circuit high codes, this represent a disconnection or open circuit, These more than likely would be a separate problem especially having the battery go flat, not only the battery go flat,and wiper goe on there own, it almost as though there is water intrusion at the fuse /relay box especially the one in the trunk area, it would be nice to have the year,
