Repair DSG Mechatronic Unit - Guide on How to repair Mechatronic unit Part 1 and 2

I decided to share with the rest of you how to repair the mechatronic units on the DSG6.
To be able to repair your own Mechatronic unit for the DSG6 DQ250 , you will need a few tools.

• A small flat screwdriver
• Screwdriver with T20 bit
• Gloves
• A Dremmel or any small cutting tool with a rotary blade.
• Some masking tape
• Silicone (the one used in cars for the windshield)
• Soldering tools and skills.
• Voltmeter

For the part one I will demonstrate on how to test the DSG Mechatronic unit and its solenoids and how to actually open up the unit and check for damage on the PCB inside the TCM.

First thing you will need is PATIENCE and some steady hands :) Also if you do not have any soldering skills or did not tried to solder before , then this is not the DIY for you, and you can stop here.

Find a CLEAN spot on your garage bench or inside your house and prepare to test the DSG Solenoids with a voltmeter as show in the video bellow. If everything is ok on the outside then you can proced to the next steps and CUT the cover of your unit in order to reach the PCB and the wiring inside.

Please watch the video and leave any questions if you have, I will try to answer the best I can.

  

I have decided to release also Part 2 of DSG DQ250 Mechatronic Repair guide :

Installing and Removing DSG6 Mechatronic Unit Tips and Tricks

Due to popular request I decided to make a short guide on how to remove and install the DSG6 DQ250 Mechatronic unit from and into the gearbox.
For this purpose I used a gearbox that I had in my garage, so it was not installed on the car.

The guide is made in form of a video and can be found on Youtube here

The torque values for the screws and the order in which the screws should be removed you can fnd it here :

The most important tips from this video would be :
- Remember to re attach the clutch speed / temperature sensor when you install the Mechatronic unit.
- When unscrewing the mechatronic unit, unscrew at least 90 degrees by one move in order to avoid gripping the screws.
- Always remember to empty the gearbox of oil before starting the removal operation. (unlike I did in the video)
- Make sure the Mechatronic unit is seated correctly into the guides of the gearbox before you tighten the screws.

Else, the job is quite straight forward and if you use the small PDF guide you should be ok.
