Title: DSG, what faults to look for ?
Post by: 182_blue on July 16, 2010, 03:17:34 pm
As title, been reading a few things about DSG boxes recently and just wondered what issues people have had ?, and what to look for if a problem appears to be developing, there's nothing wrong with mine it's just more a query :-)

When you google it, some say it's a certain age range that is affected (2007 models?) Others say all are affected.

Only thing i've noticed with my DSG is it's occasionally a little lazy to come out of first gear when I first start the car up to drive off, oh and sometimes when approaching a roundabout or stopping at lights i'll hear a 'clunk' just before I come to a stop - that's apparantly the clutch dis-engaging at the last minute so as not to stall - apparantly...


It's the mechtronics unit that appears to be the failing part, basically the ECU part of the box itself.

Mine make's the same 'clunk' noise when engaging first gear from second. I dont know if thats normal or not though.

dont be so parinoid shaun!!!

Im sure by now on yours, that most Mechatronics issues have been ironed out now.

im not sure thats true though, before i bought mine i wanted to test drive one and Arthur prince VW in loughborough had a 2010 R in white, i rang up to test drive it and they said it was off the road as they were waiting for a new mechatronics box  :confused:

Jerky gear changes, jerky set off from 1st gear. Gear symbols flashing on the highline. Hope that helps :happy2:

^^^ It's very rare for the highline to flash for the "normal" mechatronics faults from everything I have read.

From experience (of two different DSG cars with mechantronics faults) reverse gear is the first one to go and then 1st - 2nd will start to play up next.

It will also be worse then you spend a lot of time in traffic if the mechantronics is on it's way out.

I now do a DSG basic settings reset after each service on the Mk6 and it has kept it as smooth as the day I got it  :happy2:

That DSG basic reset I did myself made my car much better after the stealers had replaced the mechatronic but hadn't done the above.
Trust them to anything right? :indifferent:

oh oh, the change on mine between 1st and 2nd is a bit crap compared to other gears, reverse is ok, hop a big repair bill isnt on the way  :scared:

I used to find 1st/reverse gears 'clunky' on startup but now I don't select any gear before the engine has gone through its initial warm-up period and the result is no clunks whatsoever. My conclusion is that you get a 'clunk' either while the DSG oil is still cold or until the engine revs have settled.

I have a Revo remapped DSG and don't know how a 'Ross reset' might effect it. Looks tedious to do anyway unless, like SteveP, you are used to such things.

It isnt really a clunk when it changes, just seems hesitant and takes a little longer from 1st to 2nd, whereas through the rest of the gears, its smooth and quite instantaneous. 40k service due in 7 months, so will wait and see what pops up when it happens.....

About 3 weeks ago, i leaving my house after abour 3 minutes of driving... i never floor it until the engine is warm i.e 7-10 minutes .... anyway, i was going up this hill very modestly slow at 30mph and suddenly the it came out of gear and the highline started to flash D, P, N, S all thought numbers flash

I stopped... put it in P... turned the car off... then back on and it was fine.... was quiet a scary moment though

Thats the only problem i've had

Rich get that checked, a faulty batch went through in 2008. Did you not get a letter?

Whats it like in manual mode??
I found mine improved after its 40k dsg service. Oil change i think improved it

Mines a 58 plate... not got a letter.

Will do though.

Mine is clunky between 1st and 2nd and viceversa  - i had a DSG remap and it is slightly better - unless you are in Sport and forget to go reallly slowly before changing down to 1st!

I treat it as a quirk!

I get a bit of a clunk when using paddles changing up from 2nd to 3rd when cold..  Think it's always done it!  Apart from that, faultless!

As Saint Steve says, DSG oil service will dramatically improve this, mine was exactly like yours with a lull between 1st and 2nd, since service its 80-90% better.

Steve, fancy having a go at this, with each module where it says ON/OFF/Next what does that mean, I would assume you turn the basic settings on then off then click next is this correct?

Or does every setting need to be turned on.

I also experience the laziness to de-select 1st on moving off from cold. The box just seems to hold 1st gear for a little longer.

Other gripes I have is the slight delay in changing from reverse to first. But this is to be expected when having what is at the end of the day an automatic.

Just done the DSG reset that SteveP suggested, it was very easy if you have basic experience of VCDS then will be simple, biggest issue is finding the right road conditions for the default drive.  But first impressions it has made a big difference to pick up shift smoothness and rev control on down shifts which always needed assistance with the throttle peddle.


So well worth doing.  :happy2:

Cheers for the info Steve  :notworthy:

That looks a right PITA to complete.

When it says you need to have "ATF Temperature 30...100 °C (86...210 °F), see Measuring Blocks, Group 019."

What exactly is this?
Title: Re: DSG, what faults to look for ?
Post by: Hedge on July 29, 2010, 10:38:56 am
I am guessing they are the measuring blocks that tell you the temp of the auto transmission fluid.
Title: Re: DSG, what faults to look for ?
Post by: vRS Carl on July 29, 2010, 10:41:50 am
Ahh ok that makes sense  :happy2:

So i need to go and drive the car first before doing it?
Title: Re: DSG, what faults to look for ?
Post by: Richn83 on July 29, 2010, 10:44:06 am
Correct Hedge, block 19 measures the Automatic transmission fluid temperature and clutch oil temperature.

it sounds a lot harder than it actually is, although you will need to take a little drive to get your ATF fluid up to temperature, as even idling mine stayed at 26 degress.

After that its only a question of sitting with the engine running foot on brake, and typing in the group number clicking go and then an on/off/next button.

I will admit its a little weird as the gearbox is doing stuff and occasionally moved the car. And the drive afterwards is fairly easy, and if you cant complete all the items it will continue in normal driving afterwards.

I'm having the mechatronic unit replaced next week on my 2008 DSG. The symptoms are very clunky gear changes from first to second and second to third. It is also a bit random, sometimes it drives smoothly others like I've missed the gear changes.  I haven't noticed any change in reverse, still feels the same. I can't wait to get it done, I had only had it 2 weeks when it went so haven't really enjoyed that silky smooth gear change its supposed to have!
