I wouldn't go to all that trouble for a remap.
Many of the maps available for the majority of recent cars can have any remap loaded to the existing ECU via the diagnostics port.
The remaps these days are basically just an upgrade of the software stored in the ECU. There is no need to remove the ECU, beak it open , unsolder the old chip and replace it with a new one any more.
I don't know if you have checked out
Bluefin but they offer a map for the 2.0TDi. Many owners, including myself, have used their product so it is well tested and in my opinion complete transforms the car.
You buy the Bluefin handset from them via their Internet site.
They post the handset to you.
You plug the unit into the diagnostic port on your car and download your current map to the handset.
You plug the handset back into your computer and send SuperChips your current map over the Internet.
They analise your existing map and chose the most suitable map from their set of predetermined off the shelf maps for your particular car.
They email you your new performance map
You copy this map to the handset
You plug the handset back into the diagnostic port of yor car
You upload the new performance map to your ECU.
Very simple process. Don't even get your hands dirty.
You can use the handset to remove the performance map and revert back to standard should you need to.
have a look at
their website before you do ripping your car to pieces
