Hi all. Help again plse. My 200tdi conversion into a 90 all doin great until about a month ago when I left a heater on plugged into cig lighter and flattened the battery. Recharged the batt which is a good vw toureg one but now on 1st turn of the key there is a kind of grinding noise. If I hold it it will start after a couple of secs. However if I turn off when noise on and yurn straight back on again starts on the button. Other wise mint. Any ideas?. Battery. Starter motor. Wiring earth etc?. Ta
