Hi I have a 1990 V8 Quattro and was wondering what people thought about the Xenon-charged bulbs that Blaufergnugen is selling. Are they worth it? I also may need to replace the hydraulic brake accumulator in the next few months and was wondering if anyone had ideas on aftermarket suppliers. Thanks.
