Dieselfan, i still have the E90 but am thinking of selling it as the E60 is a much nicer ride. I have already removed the swirl flaps, had blanked off the egr and had a friend remove the yellow engine light with his diagnostics, but it came on again after about 50kms. I plugged the egr in again and the light stayed on for a short wile. Took a nice long trip to Upington on Monday and came back today. Engine light was off when i left here! Coming back today i took the long way via Britstown, Three Sisters. I had filled up in Upinton yesterday. The car has a 70l tank. There was practically no wind, clear skies, lovely day. Had the cruise on 123kms/h which is 120 on the gps. I would have made home on a tank (1100kms) but decided to fill up at Touws River. Did 905kms on 54,1l of 50ppm diesel (16,73kms/l) which i think is excellent. On coming through the De Doorns section there were some road works and we travelled at 60 - 80kms/h but i saw 21,2kms/l on the obc. I think it is standing on 18,8kms/l now and i did just under 200kms from Touws river. It amazes me that a car as big as the five can give such economy. o, and i don't have a breather in, left the oil seperator casing empty.
