part number 058-133-517. Of course engine check light came on, otherwise I would not have noticed. Tried to get dealer to recode the remote, they were trying to charge me 1/2 labor, told them that it 's in the TSB. Of course I did not have them done it and bitched at them on how they tried to charge something that AUDI is going to pay. They said Audi told them that it's not covered. Anyway, got a call back from dealer service manager later, but I did not have time to return the his phone call. Perhaps they have discovered the truth. BTW, it's from the only dealership in Austin, TX.
