This corner is dedicated to the VAG DSG Gearbox and the DQ250 Mechatronic unit that has a high failure rate.

Before you continue I would recommend some reading :

Dual clutch gearbox 02E Electrical Connections - Passat
It seems that most affected cars are the VW Passat , VW Touran and the VW Golf produced between 2003 and 2007. I have only seen a few Skoda and a few Seat.

Currently, the world of transmission is dominated in Europe by manual gearboxes and in the USA and
Japan by automatic gearboxes. Both types of gearboxes have specific advantages and disadvantages.
The advantages of a manual gearbox are, for example,
high degree of efficiency
robust and sporty characteristic.
The advantages of an automatic gearbox are, for example,
a high level of comfort, above all in gear changes, as there is no interruption in tractive power.
This formed the framework for Volkswagen to combine both transmission concepts into one completely
new gearbox generation: the direct shift gearbox.

Thanks to the double multi-plate clutch design and different automatic gear selection programmes, it is
well capable of meeting the high demands in comfort from drivers who favour automatic gearboxes.
Furthermore, with direct selection and lightning fast, jolt-free gear changes, it also offers a high level of
driving enjoyment to drivers who favour manual gearboxes.
In both cases, fuel consumption is at a par with economical vehicles fitted with manual gearboxes.

But there is a problem with this DSG Gearboxes, it's the Mechatronic unit. This unit sits inside the gearbox and it gets pretty hot and sometimes the electric valves will get defective. Also a common problem with the DQ250 Mechatronic unit
is a faulty TCM module. This is mostly seen when the gearbox oil temperature goes above 40 degrees Celsius and we will start seeing error codes as "18222 P1814 Pressure Control Valve 1 (N215), Open / Short to Ground" or some other Short to Ground errors on the other valves.

Most of the valves can be refurbished but until now I have never seen anyone being able to refurbish the Pressure Control N215 or Pressure Control N216.
 


DSG 02E Mechatronic Unit from DQ250 Transmission

Some of the most common symptoms of a Mechatronic Failure are :
 

  • Flashing PRNDS in the Dash and the gearbox will switch to neutral.

  • Hard engaging of the 1st gear (slams into the first gear) from a stand still point.  This can sometimes also be caused by a decallibration of the clutches so you might be able to "save the day"  by performing a recalibration with a VCDS cable. Procedure can be found on Ross Tech website.

  • Hard downshifting from 3 to 2 and 2 to 1st gear followed by some loud "clunk" noises.

  • Shaking / juddering feeling while in 2nd gear and the car pulls up.

  • Jerking between gears

  • Loss of power between 1300-2000 RPM. Car feels like dead

If you have any other experiences please let me know, I will add them.

For whoever needs I can supply electronic parts for the DQ250 DSG Mechatronic / Mechatronik units.

I have the following :
Pressure Control N215 Valve 1 (N215)
Pressure Control N216 Valve 2 (N216)
Pressure Control N217 Valve 3 (N217)
Pressure Control N218 Valve 4 (N218)
Pressure Control N233 Valve 5 (N233)
Pressure Control N371 Valve 6 (N371)


N88 Solenoid Valve 1
N89 Solenoid Valve 2
N90 Solenoid Valve 3
N91 Solenoid Valve 4
N92 Solenoid Valve 5

Circuit boards, solenoids and also some whole Mechatronic units are available also upon request.
Mechatronic Pressure Control Valves are available on request.


This valves are present in ALL VW/Audi group DSG Mechatronic gearboxes and usually you will be able to read one of this error codes when one valve goes :

18222 P1814 Pressure Control Valve 1 (N215), Open / Short to Ground
18223 P1815 Pressure Control Solenoid 1 (N215), Short to B+
18226 P1818 Pressure Control Solenoid 2 (N216), electrical malfunction
18227 P1819 Pressure Control Solenoid 2 (N216), Open / Short to Ground
18228 P1820 Pressure Control Solenoid 2 (N216), Short to B+
18231 P1823 Pressure Control Solenoid 3 (N217), electrical malfunction
18232 P1824 Pressure Control Solenoid 3 (N217), Open / Short to Ground
18233 P1825 Pressure Control Solenoid 3 (N217), Short to B+
18236 P1828 Pressure Control Solenoid 4 (N218), electrical malfunction
18237 P1829 Pressure Control Solenoid 4 (N218), Open / Short to Ground
18238 P1830 Pressure Control Valve 4 (N218), Short to Plus
18241 P1833 Pressure Control Solenoid 5 (N233), electrical malfunction
18242 P1834 Pressure Control Solenoid 5 (N233) Open / Short to Ground
18243 P1835 Pressure Control Solenoid 5 (N233) Short to B+
18246 P1838 Pressure Control Solenoid 6 (N371), electrical malfunction
18247 P1839 Pressure Control Solenoid 6 (N371) Open / Short to Ground
18248 P1840 Pressure Control Solenoid 6 (N371) Short to B+
 

The following error is most likely caused by a mechanical problem but can also be an error on the Mechatronic unit:

19143 - Unexpected / Implausible Mechanical Gear Disengagement
P2711 - 004 - - Intermittent
 

 

Mechatronic Solenoid Valves

If you need some of this or you have any problems with your DSG Gearbox of the Mechatronic unit please drop me an e-mail at jaxelos @ gmail.com and I would be more than happy to help if I can. I can fix /repair Mechatronic units including the circuit boards if necessary.
 

BEFORE YOU SEND ME ANY QUESTIONS regarding problems with your DSG gearbox make sure you have checked the following:
 

  • ALL YOUR ABS Sensors are working in perfect condition. You can log the signal of all 4 sensors with the VCDS Tester. or VCP. The most important one here is the REAR LEFT sensor.

  • Make sure your diesel filter is changed and not filled up with oil.

  • You changed the DSG oil and filter and you performed the DSG Adaptation correctly.

  • You have no other errors on the engine control management.

  • Your EGR Valve is in good working condition and engine runs as it should.

  • CHECK your VACUUM Pump and be sure there are NO OIL LEAKS that will reduce the Vacuum necessary for the perfect working condition of the engine.

In order to get a better overview of your problem please try to DESCRIBE the problem as good as possible but do no write me a whole novella. Remember to say "HI" and present yourself so I know who I am writing with and from where !

I will NOT answer e-mails like this :

"I have a problem with my DSG, please help me"
or
"Do you have a file for DSG6 6?"
or similar e-mail. I will try to help the people who really need the help but please do not waste my time.
If you have a LOG file with the errors of the car please SEND the log file along with the e-mail.
Send me some details about the car also : Make, model, year, engine code, gearbox code... as many details as possible.

I RECEIVE INSANE HUGE AMOUNTS OF E-MAIL RELATED TO DSG PROBLEMS LATELY AND I SIMPLY
DO NOT HAVE TIME TO ANSWER EVERYBODY ANYMORE , SORRY !!

WITH MANY PEOPLE I USE DAYS TO TRY AND DIAGNOSE A PROBLEM AND AT THE END I DO NOT EVEN RECEIVE A "THANKS".

IF YOU THINK MY TIME IS WORTH SOMETHING PLEASE MAKE A SMALL DONATION TROUGH PAYPAL.

Thank you in advance.


Here below is one of my old videos while I dismantled and put back together the DQ250 Mechatronic unit.
Some more videos will come soon. This was a defective unit and I have made the video just for documentation.
It was a long time ago when I was a noob :)

I  can also flash new software to existing Mechatronic units or repair them taking your old units in exchange.
I can also fix the CIRCUIT BOARD and not only the components in the Mechatronic unit.
