Hi all, I went out too the garage this morning and started the car and gave it a little rev and the management light has came on, It did go off after i turned the key on and off a few times and thought that was that but when i drove down the road a bit it came back on, its a wrx with a remap. also when i checked under the bonnet i noticed i must have left the oil cap on top of the battery when i was checking the oil last week.
