DSG Fault on GTI

[snedden9485]

Got my new polo and its got about 120kms on it. Driving it today in manual mode and when i was stopped at a roundabout in 1st gear, i put the foot down to go and it wouldnt go. The car just stayed at idle and D started blinking at me. The car stayed like this for a few seconds with me stranded in roundabout. I then moved the shifter into D and pushed on accelerator again, the car went forward after a second or so and continued on without an issue. Any one had similar issues?

The car was warm, i just left the servo after filling up with fuel.

This vid seems the same problem.

That does not sound good. Never occurred with mine, and I use manual mode quite often.

Working fine today and hasn't done it since. Very odd....will send it in to Volkswagen tomora for a look.

3 times in 350km now. Always in manual, 1st gear. Car just won't go for about 5 seconds. Took it to dealer yday and couldn't find anything. No fault codes or anything. Frustrating on a brand new car.

Same problem over here (in Europe) but without gear blinking and engine running upto 1500 rpm max; I solved switching off and on the car! According to a friend of mine who had same problem as yours, this can be solved upgrading DSG control unit at official assistance/dealer (he's a VW mechanic) for free!

Hmm, what Benja says confirmed my thoughts that it's a software issue more than hardware....

[snedden9485]

I have no doubt it is a software issue. Hasnt done it since (i have been using D mode more often). If it continues, I will contact VW and seek answers. Maybe a reflash or similar of the DSG would fix it.

I'd contact them again, give them that video and explain it was exactly like that, and get them to come up with a resolution.
Whether there is a software upgrade, a hardware upgrade of the control unit, or whatever

Let us know how you go.

Corey, you would know more than us (being more familiar with the dsg) but is this a symptom of a faulty mechatronic unit?

[Corey_R]

The tricky thing about the "mechatronics" is that it's the combination of the "mechanical" - the solenoid valves etc which physically operate the gear selectors and clutches, and the "electronics" which are the processors which monitor the gearbox, clutches, operating conditions, and control the solenoids etc.

So it's a pretty safe assumption that if it's not a cooling or oil pressure issue that the problem is the mechatronics. But whether the unit is outright faulty, or whether it just needs a reset or software update is another thing...


I feel that something needs to be done however. Even if there are no fault codes in snedden9485's car, I'd be wanting the DSG software upgraded, if an upgrade is not available then maybe even a downgrade if whatever the latest revisions are for is not a "critical" issue. But then, I'm not a mechanic, so...
