Anyone have problems with certain ECU’s hanging up an auto-scan with the Ross-tech VAGCOM? I had a strange problem yesterday, where the AWD controller (address 22) was hanging up during the auto-scan. The software wasn’t crashing, the scan just sat there seemingly stopped. I hit the ‘done’ button and the scan completed, however, the subsequent print out showed no errors at the beginning lines but the module scan was vacant from the subsequent report. I can post the report if this is confusing.
Made my flash take 2 hrs because the techs couldn’t figure out how to clear DTC’s and seemed to think the sky was falling. The car was finally returned to me with all the DTC’s still there and I promptly cleared them without issue.
I don’t believe there is anything wrong with the AWD ECU @22, but am curious if this is common. The problem didn’t really systematically repeat itself. I had the issue occur sometimes with car off and sometimes with it on (if I remember correctly).
