The Sirius Satellite radio in my '08 Wabbit suddenly quit, says "no Sat Radio" Sirius says the dealer needs to do a "hard reset." I called the dealer to find out if that meant simply disconnecting the battery for 30 sec or so. The service advisor told me that if I disconnect the battery the car might not start after I reconnect it, because too many things will need to be "reconfigured." I smell BS. Is it OK to disconnect the battery for a minute without the car losing its ability to run?
In my experience, providing there has been no electrical or electronic equipment change in the vehicle, all should be well. If you have an owner's manual it should warn you if there is an issue in disconnecting the battery. Smells a little like BS to me too. As regards the hard reset for the radio, you ought to be able to get a detailed explanation of what they want to do for you before you commit yourself to their workshop charges. There are detailed procedures laid down for the dealer to follow.
Let us know how you get on.
P.S. please note that I said all should be well and not all will be well . . . . (smile)
Look at your engine compartment fuse panel, Drivers side near the firewall. Look at fuse F21 and make sure that it is not blown. If that is not the case look under the passenger side trunk liner (possibly the drivers side) there you will see the sirius tuner that is most likley faulty.
So here we are what, 4 years since I posted this and I have definitively answered my own question: YES. Nothing bad happens.
The car starts fine after having the battery disconnected; on my manual trans gas engined unit the ONLY reset required is to drive straight ahead for .2 of a mile after the reconnect so the electric steering and ESP can reset what it knows as "straight ahead."
AND better yet, the battery disconnect does restore the Satellite radio. It's "blinked out" a couple of times over the past few years and a "hard reset" brings it back. Just unplugging the power to the radio DOES NOT, so something in the car is getting angry with it.
Car now has just at 290,000 miles on it, still on original clutch! Currently seeking truly definitive answer to front axle bolt torque specs for the "new" 12-point bolts.
