I have a BMW 525e 1987 model that has travelled about 310 000km. It is a 5 series with 6 cylinders. The amount of petrol it now consumes is twice its specification. It is 15 litres in 100 km while it should be 7.5litres per 100km. It's spark plugs have just been replaced and the caborn oxide it emits is still normal. Can you please tell me what the problem could be.
have the same problem?
