I then drove 2 times about 25 km – to a RASThof (in order to also look in peace, if that repeats itself), every further start was without probs, steering aid came immediately like ‘inhabited’ at the start attempt! WHAT WAS THAT?; does anyone know that possibly?; is there possibly a ‘DREHCHHTUNGSENSOR? has something calculated but found nothing. with it a few days ago something with LENKGETRIBE, LENKHILFE, etc., possibly other key word?!!(in the ESSI-FORUM)! add I still have to add, I HAVE BEFORE about 1o days ago a BATT taken over by nem friend. so his against my exchanged – action of 10 min, at most 15 min; but after that did not make a SG learning – forgot) – motor also ran quite normal, jumped normal, no signs… failure of systems – yesterday then DAS!..s.o.! oh yes, ÖLRESERVOIR is under MAX, almost to MIN,cold!(?), says someone from EUCH THE WHAT ?
