Mk3 8v GTI, PAS, ABS, Aircon etc...
What the hell is the little reservoir to the back of the engine bay on the driver's side? every time I've been for a drive, tehre's a little purple thing that rises up out of the cap of it! I've got ElsaWin and I can't see it in any of the diagrams relating to PAS aircon or brakes and I'm out of ideas now!!
Please help!!
