Hi All

Customer has come to me with merc with battery drian of 20a, found the fault to engine block heater. But he also said now will not start, will not crank, battery is full up and brand new all earths and suppy feeds good as are fuse,s the problem codes i am pulling up on texa are
P1617 ECU Eprom & P1630 Electronic immobilser.

I think the DAS module is not seeing the key code is there a way to reprogram they key back in or has some one had this fault before regards steve
