Warning lights

Going on holiday about 250miles from home and the warning lights come on with a beep. Stop car, nothing seems wrong. Start car and engine light replaces steering light and speedometer does not work. Get to destination, about 35 miles on and discover fuse 3 has blown. Start car and only engine light is aglow. Take to nearest Skoda dealer and they turn off engine light and all's well for £60. About 50 miles later same thing happens, Skoda dealer looks at car for 3 hours and say it's either the loom or the ABS pump needs replacing. All is well for some 250 miles and another £180, and here we go again! Anyone got any ideas or experience of this problem
