How VW Parts Fail ~ 7 speed DSG Mechatronic Unit

Published on September 15, 2015 under Video

VW DSG ProblemsToday on “How VW parts fail”, we are looking at the mechantronics unit from the 7 speed DSG transmission. This transmission is only found in the Jetta Hybrid in the US market. In the rest of world market, it is found in other drivetrain combinations as well. This is not the most common of VW issues, but it is pretty cool how it works. This is also a little different video because I have never taken one apart. It is great because we can all learn something on this video.

    thank you very much for the explanation about the mechatronic unit,
    i have problem with my golf tsi 2014 model the gear only shit on gear 2 & 4 sometimes 6, gear 1,3,5,7 is not there and the car gave me gear error however, i still can drive the car on gear 2,4,6, after the mechanic checked my car he said i need to replace the mechatronic unit, my concern is that this is not the faulty part that causing the issue, i would really appreciate it if you can help me with this.

    Thanks for the video.

    I’m no mechanic but just what is the mechatronic control unit.
    My 2012 tsi just failed after 40,000kms no early warning flags, just D1!
    The repair is under way now, replacing the complete control unit. Apparently, recon units are available however the cost vs warranty against new is just not viable !!
