As I said some of the problems with the DQ250 Gearbox and the MEchatronic unit from this gearbox (DSG 02E) can be fixed. Most common problems 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 , 3rd gear and the car pulls up.

  • Jerking between gears

  • Loss of power between 1300-2000 RPM. Car feels like it has no power.

Some of the affected units are :


There are many other symptoms but here I described just a few of them. BEFORE you send me any DSG problems related questions I would suggest you to try the following :

  1. Change your DSG Oil and Oil Filter. When changing look for metal residues in the oil or the oil filter. MAKE sure you fill up the gearbox oil to the specified levels.

  2. Perform Basic Settings as described on Ross Tech website.

  3. Make sure you don't have any oil leaks from the gearbox and the oil is at the correct level.

  4. Check your ABS Sensors. Check if all 4 sensors read same speed while driving. (have another person driving with you and monitoring while driving, make a log file). ABS Sensor can be a pain when talking DSG Gearbox shifting.

  5. Change your fuel filter. Especially on diesel cars check the fuel filter and see if you don't have any oil in the filter. The high pressure vacuum pump tends to fail and mix oil into the diesel.

  6. Check your DMF (Dual Mass Flywheel). Take the Starter motor down (it's 2 screws) and check if you have any play.

AFTER you have done this and you still feel like you have a problem with the DSG Gearbox or the Mechatronic module and you would like some advice, you can send me an e-mail at jaxelos @ with any questions you might have. If and when you do so PLEASE include as many details about your car as possible (Make, model, year, engine size and code, gearbox code). This will save me and you some precious time.

Here you can see why the Mechatronic unit can fail. This unit was filled up with oil INSIDE the TCM. can also flash new software to existing Mechatronic units or repair them taking your old units in exchange
