Anyone know if the Ghost immobiliser voids the VW warranty?
IMHO, installation of a Ghost immobiliser shouldn’t invalidate the whole warranty. However, if a factory fitted part of component failed within the warranty period and the cause of the failure is considered by VW / the dealer to be the Ghost immobiliser or the way it’s been installed, then it’s likely the warranty won’t cover the cost of repairing or replacing the failed part.
Therefore something such as a failed suspension component or wheel bearing should be covered, but the car’s battery ‘dying’ prematurely due to parasitic drain attributed by VW to have been caused by the Ghost immobiliser is unlikely to be covered.
