Title: ECU reports that security access is not supported on 1.8t resolved Post by: Jeriho on March 13, 2015, 11:19:44 PM So i have been trying to read a spare ecu for my s3 8l. Done the immo defeat and it still wouldnt read. Keept giving the "ECU reports that security access is not supported".
After searching for quite a while i found some sugestions that on 1.8t pin 121 has to have 12v. After trying that works perfectly. Just in case someone needs this.
