Hi Wilcoman, UAE is not good, at least if it comes from the EU (e.g Germany, NL, Scandinavia etc) it will have amn EU certificate of conformity, I bet yours coming from the UAE doesn't it doesn't sound as if it it to UK spec, if it doesn't come with a EU Cert of Conformity it should have had a single vehicle type approval test when it was imported, you may need all of this documentation when you come to sell it, what does the V5 say? does it say who imported it? You need to check it has been properly registered when it was imported.
Was it sold as an approved VW car from a VW main dealer? If yes then it won't have been covered by their approved used scheme, they don't cover imports, I took my EU import in for a trade in to my main delaer and they wouldn't touch it saying they are not allowed to sell on non official UK imported cars as they are not approved VW cars covered by the apporved VW scheme warranty etc, If it was an approved VW car from a main dealer I would be demanding my money back and the garage take it back, if not just a used car from a VW specialist it all depends on how they described it........
Good luck
