sorry but my vaux looks far better than the mk5 gti, thats why i bought it faster too
As correctly stated the low washer light is indeed part of the winter pack. However it can be programmed specificially by VagCom. So if you ask your dealer nicely the low washer light feature can be turned on on any MK5 Golf.
its a bit poor if it can be switched on with vagcom, it just seems like vw conning people into buying the winter packit is a useful feature, was on my mini cooper before because the windscreen wash reservoir was smaller than a can of coke
