DSG box slipping into neutral

[wingnutLP]

Hi all,

Three times in the last few days my dsg box has slipped into neutral.

There doesn't seem to be a road speed or throttle input pattern. twice it just went back into D but once I had to stop thankfully in traffic and move it to P and back again.

The most recent time all the gear selector lights on the dash flashed while it was in neutral and until I managed to re engage D. It may have done this the other times but I didn't notice.

Any ideas?

If it happened on the motorway it wouldn't be great fun

sounds like the mechtronics unit failing... it was a common occurrence with the MK5 DSG boxes.

Is the car still under warranty by any chance?

We had an A3 that was doing the exact same thing last week, new Mechatronics unit solved it.

As above mechatronics unit, had mine changed under extended warranty

I had this problem, went to VGS and it was the part that selects the gears, not the mechatronics unit thankfully! Was £500ish if i remember correctly

iirc another member on here had a similar issue that turned out to be the selector mechanism and not the mechatronics unit.

no warranty but had a new mecatronics unit under warranty when the car was less than three years old.

How much would a mecatronics unit be?

grr, I could do without this...

Try a DSG reset via VCDS, you might be surprised :-)

Well it has not done it again but if it does I will give it a try.

Thanks for the suggestion.

I think my VW invoice was in the region of £1,900 for the replacement covered by the warranty.

F!!k would a car of say 5-60k miles be worth checking over?

Even if your car is not from 2009, I thinks it's worth checking the sensors first. See below.

On Aug 2009, VW started a recall on 2009 and 2010 DSG on the temperature sensor. Models affected are built between August and September 2009.
A faulty temperature sensor can result in illuminated warning lamps in the dashboard and the transmission may shift into neutral.
It appears that both sensors below are in the same assembly.

Can someone explain to me the way they use the DSG gearbox when coming to a stop at traffic lights for instance.

Do you slip it into neutral then back into D or leave it in D with the foot brake on?

[Top Cat]

Your supposed to place it in neutral just like a conventional box, something to do with the oil temps rising left in D when stationary but i am sure most people dont bother and have not heard of any problems due to this.
