my 08 cobalt ss is at the dealer and they say they are having problems flashing the ecu did anyone else have this problem?

 

they could be having issues having the tech tool contact the internet, that has happened to some.

 

yep I had that problem when I was having mine done at the dealer,the vcn number that the kit came with was not working,they tried many different options and finally called and got another number,went right through and all was good!
