Never had an issue with the check engine light before the RC. Since uninstalling it this weekend, also no issues. Pretty sure that’s what’s causing it.
The company in Germany is initially rejecting my request for a refund, stating that I’m past the 30 day warranty period. Of course they aren’t accounting for the fact that they initially shipped me a defective unit from Germany that I had to install, troubleshoot, discuss with them, exchange for a working unit, and then reinstall this past weekend, only to find the new issue and contact them within a day of doing so. I’ll be pretty ticked if they refuse it after this ordeal.
