1. The Xenons fitted to South African GTi's have sensors on each wheel that adjust each headlight seperately so that glare from the beams will not be a problem to oncoming traffic- I assume this is the same as UK GTi's?
Technically, not quite correct. Just one front and one rear wheel has a level sensor (think they are both on the left side), and the headlamp beams are both adjusted simultaneously. This appears to be a world wide requirement.
2. Washers are an option on South African GTi's. You either have them or you dont. The reason for this is to keep the cars price down. The washers are however an option. Hence the two piece trim on the bumper. However vehicles like the Tuareg and Passat have to by law have washers here in SA due to the bulb being more intense or brighter on the larger vehicles.
Hmmm - struggling to agree with all that. Yes, I accept that headlamp washers are an option for the halogen headlamps, and the need to keep prices down and all that. However, what they say about the two peice bumper just dont add up. If you have NO headlamp washers, then there is a one piece filler trim on the bumper below each headlamp. You only get the two piece bit if you have headlamp washers (for halogens or Xenons). Hading been fiddling, the smaller outer piece of the trim is actually fixed to the headlamp washer jet, and being as your pics clearly showed a two-piece trim, then you must also have the headlamp washers. I really cant see South Africa being on their own on this issue, because everywhere else in the world, it is compulsory for the headlamp washers with Xenons. When I was in Morroco 18months or so, I stayed in a posh hotel, and the Mercs and Beemers, and even Passats which had Xenons had the washers too.
Did you manage to pull out the plastic trim cover from the bumper? If not remove either of the fog lamp grilles (one phillips screw, and then gently pull out), and you can clearly see the pipework for the washers. I seem to remember your stealers were crap when trying to sort you self opening electric windows!
Interestingly enough our parts etc comply to European and American laws here because we ship vehicles to America apparently and certain vehicles (didnt ask which ones) get sent to Australia which apparently also falls under European law. So we really are the rainbow nation 
Well I'd stick my neck on the line and categorically state that you must have headlamp washers in south africa. Have you asked on VWclub.co.za ?
We however have our own laws as stated above and the GTi does not fall under the category that needs to have washers. All three of the techies also mentioned climate etc. But I zoned out as Gossip Girl came on. 
^^^ Huh ^^^
Problem solved.
Not so sure . . .
