Another thank you for Rufe here as well.
Provided the code for my son-in-laws S40 after the battery had been disconnected at a previous service (independant garage). My daughter and son-in-law had taken to 'stealing' my wife's Focus or my T4 'because they've got music' but they've got no excuse now!
They've got a 3.5hr drive to do Friday so were seriously happy last night when I gave them a code that worked.
Once again - many thanks Simon
