hi all, i dont know if im in the right place but even though i will try:
i have a a3 2008 bwa engine with the dsg6 dq250 transmission, car with 204,000km, completly stock.
the problem is from 1st gear to 2st gear and 2st to 3st when shifting, (and sometimes also from 3 to 4) exactly after the shifting point the engine make "jerks" like pull the ignition off and on for a half a second and after that keep going like nothing happens. its happens only at D and around 3000\4000 rpm driving. if i drive in manual mode or S mode its not happen at all.
in vcds i dont get any fault codes at all.

i replace a new geniune r8 coils, new ngk spark plugs, new geniune pcv valve (last revision), new geniune diverter valve (last revision), new geniune hitachi MAF sensor, new geniune air filter, transmission oil and filter replace also with new geniune ,and new geniune n75 sensor. i really cant solve or understand this issue at all.

i put here also the log i do today in 3st gear - LOG-01-015-028-034-313-331-1148-115C-1418-1434.xlsx
is the car behave good? boost is in the right values?
thanks in advance.

Why do you think the engine is causing this rather than the transmission?

The transmission isn't showing any fault codes either :confused:

Not all mechanical problems will generate fault codes, only those that VAG included into the diagnostic stack in the module firmware. In situations like this it's down to proper old-fashioned fault finding using an understanding of the mechanical systems involved not just the electrical/electronic systems.

The point I was trying to make is that you've been working on the assumption that the engine is faulty despite their being no engine fault codes, but when the transmission is suggested as a possible cause you appear to reject that suggestion on the basis that there are no transmission fault codes - seems inconsistent logic to me?

Sorry i dont really understand you.. you recommended to check the transmission if i right, but how and what ? :) i think the only serius test for this dsg6 checks is pull out the mechatronics unit and check it on the bench like all the valve and solonoid etc.. this what you mean ?

Not sure if I'm understanding the symptom correctly, but could it be clutch plates not picking up the power correctly so you get a dip until they bite properly? If they are original then I'd be looking at them after 200k km.

I'm going to let those with more experience of the DQ250 transmission than me suggest the best fault finding method.

Not that sort of thing. A decent mechanic would have a feel for what was causing it though. Sometimes the analogue world still tells us more than the digital one.

OK, but the condition you're trying to correct only happens when the transmission is shifting from one gear to the next, right?

Even if it feels like the engine at that point, keep in mind that the a DSG transmission can and does request torque reduction from the engine during shifts, and if a shift doesn't go as planned or expected, such a request may last longer than usual.

Understand
But dont know where to start in the transmission.. apart it?
And o fins a way to check the clutchs on the dsg via vcds:
Waht do you guys think on this ?

Is your car an R8? I'm pretty sure the transmission in an R8 does not resemble your 02E in any way, shape, or form. ;)

Have you checked the fluid level?
When was the last time the fluid was changed?
Have you tried running the complete Basic Settings sequence on your transmission?

-Uwe-
Oh sorry i dont was see its an r8 forum.
Yep the fluid level is good we change transmission oil and filter about 6k km ago with geniune.
i also was do the basic settings on it. (3 or 4 times../:)
I have to say that from yesterday when i was do the logs with vcds.. after i finish them i drive with the car near 200kmh for seconds and since i dont see the problem.. very weird..
