Electric motor for €1700 (YARIS) !!!

After my Toyota Yaris 1.0 Freetronic didn’t work (repaired 2 times on warranty 3 times so far), the liquid was replaced and we were told that the car could run for 2 weeks or 2 days until the error occurred.One would have to replace the pressure storage (cost approx. €800).The car has been running for about 1 year without any problems…until last Sunday. Then the same problem came up again.We decided to do the expensive repair and the Dr. Said done!!! Today came the call from the workshop: -the electric motor of the pump which is responsible for the pressure setup in the pressure storage is defective (collector dissolved!!!). -the electric motor is NOT available ONLY ONLY with the complete pump!!! Additional costs cca. € 1700 (+MwST and work) !!! Totally over €2500 !!! ~5000 DM !!! New car price was 20000 DM !!! Toyota???? Nothing is impossible!!! Toyota??? Hmm….. Nevertheless, on references the mi I am grateful to you for your help (repair, etc.).
