Just got a second hand ECU that has been remapped to 215bhp. Same year and same model as mines.

Are there any dangers to look out for when swaping them over?

Cheers.

Yup, it'll need coding in or the immo defeated first

What other mods did the donor car have?

How much will that cost??

As far as im aware it was just a remapp.

When I got mine I think someone said that someone on here would do it for about £20 but fortunately it was already done. The only difference I had was that the previous car didn't have cruise control which means I now don't have cruise control until I can get someone to activate with VAGCOM I believe. Although I don't really miss it as I don't really do much motorway driving.

You cannot just swap the ECU, its not straight forward at all. You need VCDS.

 

The engine ECU must be matched using VCDS to the immo chip in the instrument cluster, otherwise the car will go nowhere.

Mine was immo removed already so it was a straight swap for me.

How much did the lack of an immobiliser add to your insurance?
