Yeah definitely worth actually taking a trip and looking at them for myself as I experienced when trying the exact same thing at the Audi dealers with the Exeo. The apparent 'parts manager' comes out to take my query about LED number plate bulbs....his reply was "audi's don't have LED number plate bulbs, I think you mean Mercedes. ..." I dragged the silly smug B@#!÷×% over to every car in the showroom...R8, A4, A3, A5, A6 and soon he realised he should never have got the job as a 'parts manager'. Really hacks me off when they just try to fob you off as if you know nothing. There's only Dave at Sere NI who knows what he's on with!
