Hello everyone. I have a 2010 XF 4.2. The car was running perfect. I dropped it off to the detailer and now it cranks like it wants to start, but wont. The detailer said they detailed it, started it, drove it into their bay for the night and the next morning they tried to start it to bring it outside, and it wouldn't start.

These are the OBD errors i got: fuel pump authorization invalid, ignition authorization invalid, invalid transponder

 

Maybe they flattened the battery

 

Can you check for spark and fuel?
Any chance this might be "bore" wash?
