Do Tach together, I am the owner of a Phaeton W12 and wonder how the Vmax suspension goes? I drove on the A65 (Landau -> Ludwigshafen unlimited) at full speed last night, the speedometer moved at 260 – 270km/h and after GPS measurement with my iPhone it was 261km/h. However, I am of the opinion that a 6.0l W12 with 420hp should achieve significantly more, I once heard something of a coding to be able to unlock the Vmax, only where do I get it from?
