Hi all can anyone tell me if a Votex alarm system is a factory fit? I am having a few problems with one on my car and when I found the siren buried in the rear quarter it has VAG plugs/wiring into it so not sure if its after market or not? I will upload some pics later today but any advice would be great it also seems to have an immobiliser in the boot which I have nno fob for this is also connected into this votex system, Thanks in advance.
