    2010 Jetta RNS315 alarm question

    I have a 2010 North American Jetta TDI with a RNS315 radio that has gone bad. Itís draining the battery. Can I delete it from the ECU, pull the harness off it, and not have it impact the alarm system? Dealer tells me that if I pull the harness of it, it will cause issues with the alarm. Dubious as to that claim. Need a few days to decide what I want to do next. Thanks!

    I think if you pull the harness and take it out of the Gateway's Installation List, it should be OK.

    I don't remember whether the the RNS 315 is in the Gateway as 37, 56, or both. Uncheck whichever (or both).

    Scroll down to the 37 and 56, make sure both are un-checked.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.
