Error P175D – DSG DQ200 – an idea what it is?

What’s going on in the round? What’s going on in the round, I’ve been looking for an error: Number: P175D: Coupling 1 opens unintentionally Type of error 1: DTC_KWP2000_ERRORTYPE1FST000000 Type of error 2: sporadically Number: P175D: Coupling 1 opens unintentionally Type of error 1: Upper limit exceeded Type of error 2: sporadically to fight. To the background: DQ200 in Fabia II year 2010 , which was acquired as a new car. In 2011 the mechatronics was exchanged “on suspicion”, afterwards 2013 new coupling coverings were given. Both measures had no positive effect on the constant plucking and hitting of the DSG. Since the expiry of the guarantee in 2015 no further repair actions, the switching was becoming more and more violent. Recently transition into the “emergency run”, gear display flashed. The friend would like to change over the mechatronics again?
