In the last few days a few times the battery on my A3 1.8T (97) had to be disconnected. When I read out the error memory yesterday, an error appeared which was not there a few days ago; 17967 – throttle control unit (J338) Error in default P1559 -35-00– An adaptation is however not possible (I read that the error memory must be empty for this). However, the above error cannot be deleted, therefore no adaptation. I thought that the DK vll is blocked by dirt, but after cleaning nothing has changed (except that the idle is now at 1070upm). I don’t know how to solve it now.
