I think machines might have a sense of humour.
Last Saturday I collected my Audi after a full service and M.O.T. Great garage, been faultless for ten years plus. Drive 20 miles home and when almost there the oil light flickers briefly and I'm told to top up. Odd when 7 litres went in that morning after an oil change. Anyway, I added a half litre and waited 10 minutes to check the level (this Audi has no dip stick -except me- and the electronic version needs to limber up it seems.) Checked drive under engine, no sign of leaks.
Early next morning, half way on a 60 mile journey the oil light comes on and screams at me to stop. I do so into a deserted shopping centre. There the engine dumps huge puddles of oil beneath the car. Roadside recovery take 2 hours to arrive and meantime the shopping centre comes alive and the car park fills. An elderly lady falls in the road 20 yards from me and the ambulance delays the recovery truck from reaching me for 45 minutes. Lady seems OK.
Cracked oil filter housing. Coincidental with garage changing the filter? Who knows; I won't make a fuss, they are good poeple.
Car lifted 50 miles to my car repairer but lorry sat nav takes us onto a z shaped narrow bridge that we cannot get over. Huge fun reversing off it and then a 10 mile detour. Get home 6 hours later. Put kettle on. Fill cafetière. Pour self cup of nearly boiling water (forgot to put coffee in cafetière.)
