Hi people,

I stupidly left the interior lights on in my '97 V40 on saturday eve in a multistorey car park and when i returned to the car on sunday (1pm) the battery was absolutely flat.

As my brother had a trickle charge/engine starter unit in his boot we tried that. It plugs into the cig lighter of each car and after 20mins or so supposedly gives enough juice to crank. This didnt work so we bought some jump leads and the car started fine and ran perfectly as normal.

The odd thing is that the engine management light now flashes rapidly at below 1500 rpm but goes out as the revs rise. The car runs perfectly and ive now done 140 miles since with no change in performance/economy etc.

Has anyone had this problem before?

The cig lighter gave out a couple of sparks when the charge unit was plugged in and i wonder if this damaged the notoriously fragile electronics? My V40 is base spec; single airbag, no aircon etc and has never shown any warning lights before.

Thanks,

Joe
