2000 Passat Battery Change and Computer Reset

When I took my 2000 Passat in to have the dealer replace the battery they said they had to reset the computer to synchronize the new battery with the automatic transmissions electrical shift module? Are they blowing smoke? I have never heard of this or found any information on it from VW. The cost is a whopping $209!

Please help I think the dealership is crazy :screwy:

The ECU will store a code for battery going dead or being disconnected. I had it happen and it showed up on the read out. You can get an "approved" battery form Sears for ~$100. As for it effecting the way it runs, kinda doubt it.
