OK, well as i said i can call in when i'm in the area which shouldn't be in too long as i already have another customer in your area wanting me to come down. He wanted to wait until i had somebody else near him so he could split my traveling costs with the other customer
 
you could try phoning Seat. Tell them you've just bought it & the remotes won't program. Tell them the remotes have been tested & are fine & you think the CCM has been changed. Some dealers are quite helpful & will tell you what part number it should have
 
in fact i've just remembered somebody i know has a 2000 Leon. I'll give him a call tomorrow as he's only down the road from me so will check his with VCDS
 
Bought the other CCM - 1J0 959 799 AH and doesn't fit, Plugs are different when forced fit (Didn't break anything) The relays inside just continuously switch when connected.

Only other thing I can now think of is try and find out what part number key fob should work with the 1C0 959 799 F
 
Oh bloody hell! That's weird considering it uses same remote part number that yours should use. Try phoning Seat to see which part number CCM yours should have
 
Just had another look & seen 1 with same part number as CCM fitted to your car & it lists it for 2002-06 Leon which uses CT remote. Which I tried the other day & that didn't program to it neither
 
Had VCDS Plugged in for a while this evening again. Still no luck!

Went through the measuring blocks and as expected I get 0000 for remotes. Im determined to sort this!

There has to been and aerial lead going into the CCM to pick up the signal so it is possible this is buggered. Now the question is which one is it?

Still stumped by why the stored value is 1 on remotes adaptation after I have reset it on ch00 surely ch1 should go to a stored value 0 if not fobs are synced?
