@ HDDP - nothing to wonder - see what i wrote in brackets - (i'm - like they - located in Austria so it's logical to go there). You may not have thought of it but i'm located in EUROPE. If i would send my ECU to the USA i'd obviously just pay shipping BUT if i get the ECU back from whomever i've to pay shipping, tax and customs - FOR MY OWN ECU !!! So what for you is an easy task would cost me a fortune. With that in mind i think the second choice (if Upsolute is considered as such) is better then paying a lot of money for a (maybe!) better result. Guess you got my point.

@ x´ed - as said to HDDP if there would be a trouble-free and cheap way i would for sure consider it.

Btw - meanwhile my XF QP has arrived ;-) (saphire silver blue, AT, with grey/grey interieur).

Anyway - thanks for your feedback which i really appreciated.
