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.
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 :
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.
Perform Basic Settings as described on
Ross Tech website.
Make sure you don't have any oil leaks from the
gearbox and the oil is at the correct level.
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.
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.
Check your DMF (Dual Mass Flywheel). Take the
Starter motor down (it's 2 screws) and check if you have any
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 @
gmail.com 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.
Autostarter.dk can also flash new software to existing Mechatronic
units or repair them taking your old units in exchange
