Dealer doesn't sell it. Once you install your Alarm, get it activated by the dealership and then install the shock sensor. The sensor is "DEI 504M", . Cost $15-$20. Do a search on www.google.com to find a cheaper price or ck here http://www.audiowarehouse.peachhost.com/ct_PR13495777.htmBMWERKEN said:How much is the Shock sensor from the dealer? And do I need the dealer to activate the shock sensor separately or can I just install it on my existing OEM alarm and have it work?
I take delivery of my 04 330i tomorrow or Saturday and my dealer tried to charge me $800 for the OEM alarm. I bought one off Ebay last week for $170 shipped Installation looks simple from the online DIY.Scrith said:My dealer (Peter Pan BMW) quoted me something like $730 for an alarm (2004 330i)...isn't that a bit much? Can anyone give me a price quote they've gotten from their dealer?
