I have a Volvo S80 and wanted to program a key using TMPRO2 after reading the CEM i programmed the key and wrote back the file now i don't get any lights on the desh,its like my CEM has crashed.
Has any one had such an issue and how did you solve it?

 

The only way that I know of is recovering the CEM using VIDA so you'll have to take it to a dealer or someone who has VIDA

 

Thanks for the reply m8,is this a online recovery or any vida software can do this,if so do have a step by step guide?
