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 :scared:
-
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 :happy2:
-
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. :happy2:
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.

Car I'm looking at Saturday is a 2007 is should ok I guess?

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?
-
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. :happy2:

For me it depends on the expected length of the stop. Usually flick it into N unless it looks like it will be a quick stop.

That's what I used to do, if it was less traffic lights just changed straight into neutral, if it was shorter stop leave it in D.

Bugger this problem has come back. Someone suggested a dog reset via vcds can someone elaborate as to what this means?
Is it a diagnostics plug in and reset and if so is it back to vw or would independents be able to do it?
By the way I have never out the box in neutral when driving, I didn't even know you were supposed to!
-
If you keep your foot on the brake when in gear, you'll feel it reduce the torque through the transmission. Leave it in gear with only the handbrake on, and you'll feel it pulling.
-
There DSG reset guide is Here (http://www.mk5golfgti.co.uk/forum/index.php/topic,24158.0.html)
You will need VCDS :happy2:
-
Diagnostic said temp sensor on gearbox as previously suggested. It was just me driving through puddles too fast.
Re neutral, if your foot is flat on the brake and you are not moving it feels to me like the clutches completely disengage so I can't see a big need to put it in neutral.
I am not going to bother that is for sure :-)
-
I don't think the DSG is designed to be held in D with the brakes on for a long time.
It emulates creeping that you get with a normal manual gearbox by inducing slip on the clutchpacks. They are wet clutches so it's not as bad as slipping a normal clutch in a dry clutch car however nevertheless is not ideal for long periods of time..
-
Additionally the dsg oil temp starts to rise when you stop in D with your foot on the brake after a short time.
-
Surely after a period stationary when the gearboxes senses the wheels are not moving and the brake is fully pressed it just fully disengages the clutches? Then when the foot comes up it comes up to biting point and starts pulling.
Clearly all the sensors are all there so why would it keep slipping the clutch rather than disengaging?
On the original topic it is still dropping into neutral even just on a wet motorway run so I think the weather sealing on the sensor must have gone.
Is the temp sensor on the top or bottom of the box? I couldn't see it on the bottom anywhere.
-
I had the temperature sensor changed which was an oil out costing £300 at an independent and the problem seems to have gone away.
Thanks for the advice.
