Hi All

This is strange i have an audi a4 1.9 diesel, i about 2 months ago lost all my keys and had the car reprogrammed and got new key. all was okay for 4 weeks
starting okay, now i have a probelm on saturday i used the car started okay
sunday it started and then the fuel cut out and the key flashes on the instrument panel and hazards are flashing, take the key out and the hazards are still flashing, so i disconnect the battery , hazards stop so reconnect the battery, go out monday no probelms, go out tuesday and have the same probelm as sunday, went out today no probelms, this as been happening for about 10 days now but not everyday. seems to be every other day. does anyone have any ideas please, it would be appreicated
