well, fitting aftermarket suspension components will probably void any warranty related to stock suspension components, springs, CV joints and driveshafts, to be honest
It won't affect warranty claims for items such as stereo, engine and electrical items, etc
That's how I've always understood the general principle...1 item can't really void the entire warranty for all components...and I think a court of law would be interested to learn from VW exactly how a suspension modification could void responsibility for stereo problems, for example
