Hello

Over the last few weeks i noticed that my freelander td4 has not been starting as quick as it normally did,usually starts 1/2 turn of the engine but now takes 2-3 seconds
So had it checked out with a snap on modis scanner and the code
P1DF5 came up saying Anti-theft device signal
Can anybody throw any light on this
Also code PIE25 was there saying speed sensor monitoring
any info would would be a help
Cheers Graham
