what do you think to this Remapped ECU VW Audi Seat Skoda 1.9 TDi EDC15P+ Plug and Play! All Models!! | eBay
remaped ecu with immobiliser disabled so its plug and play but supplies the code so you can code the immobiliser and re enable it if you have vcds!
These will just be a generic remap obviously
there is a thread on how to remap with cables off ebay and blacksmoke remaps but this could be a cheaper option!
