hi there its a petrol not diesel

[paul11]

have you disconected the battery recently? i only ask this because my battery went flat a couple of weeks ago
and i have the same symptoms,but believe it will sort itself out because the ECU has reset its self to factory settings,you need to do a few miles
for it to sort itself out
