The key , imob and ecu MUST share the same code so you can see the issue.
 
Would have been ok mate if you sent the ecu you are using in the car now, but because it all needs pairing up that's where the cost will come in.

I agree. It aint the tuners fault.
You should of just had the car off the road for 48/60 hours and used your existing ECU.

There are ways to sort it out and it shouldnt be that costly, although it will probly be a big pain in the a*se.

hope you get sorted fella.
 
Cheers, Yea im hoping that i can get it sorted soon aswell. Was tempted to take the ecu and clocks with me to GTI International and see if they could be sorted up there but a bit risky to try and get it sorted a couple of hundred miles away but suppose if it goes pete tong then the RAC will tow me home and il save some petrol lol ;).
