Hi Wendy
Are you sure your reading the oil level correctly as when i first purchased my A2 petrol it was a nightmear to get a correct reading due to oil buildup in the connecting tube , as every time i checked it gave a false reading, especially if checking on a warm engine, Best to leave the car parked on level ground and check before starting first time of the day, If the alarm is for low engine oil it means youl need to put 1L of oil in approx as thats what it needs from bottom mark to top mark on the dip stick and the warning flags up at roughly bottom mark i think, i removed my corrugatted pipes that connects to the sump from the dip stick and the oil top up part that swivels out with the oil cap on and cleaned all these parts up as only held in place with a few screws and the swivel part seperates once removed which made things so much better ..
