so.. was today at tüv wanted to make the hu. ran everything wonderful, he asked me questions to my r (was after my answers enthusiastic about the dare) but when then came the off and he orb plug plug plugged in then still the off-sond in the exhaust, he saw that the speed was too high! (now was nothing more laughing at the examiner!) he asked if I would have made a chip or anything else on the car according to his specifications MUST lie the empty speed between 600 and 700 revolutions, mine had 778! hmm on what can this be? the operating temperature was at 90° I had once got a new motor hull, can it be that it is because of it or has the tuv`ler only false information? well, first make a date when nice.. gruß sascha.
