Right - the changes came when the mk4 was overhauled to "90spec", which funnily enough actually came out in late '89, so F platers on wards.... Revised front bumper, "winged" rear spoiler we changed, along with the interior trim, dash clocks, and e/m, e/w, fuel comp and heated screen all came as std....
Can't quite remember off the top of my head but IIRC, the fuel comp shows you;
- Average econ
- instant econ
- Range
- level
- distance traveled
