Scirocco Central

Does anyone know whether 37G7 would be applied to a week 36 2010 car please? I am referring actually to my post about slow gearchanges (between 1 and 2) http://www.sciroccocentral.co.uk/forum/ ... low#p91111" onclick="window.open(this.href);return false; from about 6 months ago.

This by the way is on a 7sp DSG Polo GTI we also run, (my Scirocco is manual). Near where we live there is a very short (steep) hill and the gearbox always drops a gear more than I would like. I always override it but when I reach the top of the hill and have gone back to full auto - the gearbox is then very tardy to change up to 2nd gear, often prompting another override. This is back on a flat piece of road.

This is really annoying. I think you suggested last time Chris that it could be the timing (cancellation) of the manual override even though the dash displays "D1", and I am just wondering if 37G7 would help, but my guess is that it would already be applied to a 2010 vehicle.

Cheers.

You need to hook it up to the VW VAS system to find if it applies to the Mechatronics fitted to the Polo. Five 7 speed DSG's used so far on the GTi and its only certain Mechatronic unit builds that have the software error.

37G7 sorts out a long tern non-use/storage of car, a problem where the software control of the DSG Mechatronic valves has an error leading to no drive engagement. As that is the latest, the software for rough roads control changes will also be loaded as part of the new software build. With it you will also get slightly different gear change/kph points and quicker gear changes.

The software error in the control of the Mechatronic valves won't sort the high first gear being held.
Gear change..... very short first, long second, reverse of the gears rpm range as now. But it will still use gears to higher rpm as the Mechatronics needs going up or down hill. This is about having the car in one gear (2nd) with no clutch adaption happening at the rattling point.

but my guess is that it would already be applied to a 2010 vehicle.

Indication is that it is only applied if the DSG if it makes the rattling noises on rough roads at slow speed when the owner raises it with the dealer..

How steep is this road?

Even after the change, if done, the Mechatronics will be looking at the accelerator pedal's demanded torque. So would expect it to rev higher if its 1:3 --> 1:5 steepness.

Many thanks indeed Chris for your very detailed reply. Yes - this road is a fair old gradient, probaby about a 1:4. I would need 3rd to get up it in the Roc but 3rd on a 7spd sounds like it is revving the proverbials off it.

That is my bugbear, the gearbox does not seem to like the fact that it has been overridden (to 4th), then at the top of the hill after coming to a stop, 1st is held for what seems an age, then it goes to 2nd gear, despite now being on a piece of flat road. Once it settles again, gear changes are quick as per normal.

Cheers.

UPDATE ON ORIGINAL POST

Car booked in for a week on Monday (VW Manchester) for diagnostics on my faulty 7 speed DSG.

It could be one of three things:

• • Faulty mechatronics unit
  • Faulty clutch plates
  • Or combo of both

Will keep you all informed as to the outcome.

Makes for an interesting read that and also makes me glad I have 6 speed dsg...

UPDATE ON ORIGINAL POST

My car finally went into VW Manchester yesterday for the DSG problem to be checked under warranty. I've been monitoring it for a number of months now but finally decided to book it in and get VW to look at it. They tested it in the garage and then one of the technicians had to take it home to test it further on a longer run (because they couldn't find any fault in the garage).

They called this morning to report they can't find the fault with the DSG box. Not happy - but what can I do?

Admittedly, the darn problem is intermittent which are always the hardest to diagnose.

So, the situation is I'll have to wait for the fault to become worse and constant for VW to 'spot it' and carry out any work under warranty. Not great is it.

The fault isn't awful but the box is as silky smooth (through 1st and 2nd in low speed traffic) as during the first two years of ownership. I'm a bit worried the problem could get worse when the car is out of warranty (mid-nov 2012).

Any other help or tips would be welcome.

Footnote: Courtesy car was a VW Jetta TDI Bluemotion. Couldn't be more different than the Scirocco. Soft seats, soft pliant ride which absorbed bumps fantastically well and stop-start tech which is very odd (but I guess you'd get used to it). One major plus point was how well it was screwed together. No squeaks or rattles what-so-ever! Biggest downside - dull as a turd

I had the 37G7 update in July 2012 but it did not solve the juddering problem between D1 & D2. The car was sent in again for another assessment in August 2012 & I was told that the clutch plate MAY have to be changed but no word from my VW SA despite numerous phone calls. I am getting rather annoyed at this point - first the mechatronic failed & had to be changed; now this

Sorry to jump onto your forum guys, but i have this issue with my 2011 A1 1.4 s-tronic which i think is the same box.
My dealers are just waiting now for the updated Clutch pack to come in and then they will fit it to my car, but there has been no mention of a software update to go with it, any thoughts
From what i have read on this thread there should be one to go on after the new clutch pack has been fitted.
It would be nice if there was a software update to alter the gear change speeds because mine really labours, revs to low in 6th and 7 gears.
Or have i misread it.
If there is a software update what is the code please.
Cheers.

The codes depend on your gearbox build and when built. There are loads depending on a lot of factors. So what is your current?

C.

I have no idea
My car is a april 2011 Audi A1 1.4 122 bhp s-tronic
Is there a sticker on the car i can get this info from.
Is the update this 37G7 ???
I am after the update that changes into gear at a higher speed/Revs to stop this labouring
Cheers

No, 37G7 is not a gear change point update. And will not always apply. The 37G7 change is selective of which gearbox is fitted. If your dealer didn't advise you now or at a previous service, its highly likely that your DSG is not affected. 37G7 is to do with a period of non-useage and valve problems leading to loss of transmission drive. Nothing to do with DSG change points.

Sounds like yours is being fixed for clutch shudder, hence the new clutch pack. For that there is no accompanying changes to the DSG firmware.

If you haven't got VCDS, then can't help.

C.

Do you know what the software code is for this DSG change points update is at all.
Cheers.

Yes, it was available in build from 01.07.10. So your query is irrelevant. The update on changes affects the D1, D2 & D3 operations due to the 3rd gear's gear teeth starting to chatter due to engagement of pending D3 but with no drive load as the DSG is still in D2 drive. So the slack engaged D3 gear not in use makes a vibration noise. This is the chatter noise owners hear if their gearbox is affected. I don't get it with mine.

So they shifted the lower gear DSG7spd D1/D2/D3 change points to ensure D3 was not engaged awaiting use at slower speeds. Also they speeded up the change over time of gear change, so when the aniticipated gear was engaged but not under driven load, this period was minmised.

To be honest, the DSG7 speed D6 & D7 gears are "overdrive" & "super overdrive" gears. If you want it to move in those gears, put it in Sport mode or override with paddle shift (down) if it is fitted to D5 gear setting. DSG7 is not a "sports" DSG, thats for the DSG6spd.

Mine drives at 30mph-ish in D6 at around 1,200 rpm and is in D7 at 35mph-ish at a similar rpm. I wouldn't expect it to pick up from there without assistance by me overriding the gear selection which I usually do with the "-" downshift paddle.

As before 37G7 does not affect gearshifting changeover points directly. The Campaign doesn't affect all DSG7spd, VAG state that "Note: Not all vehicles are affected by this campaign! Before a repair check with the application". Its implemented for sticking valves in the Mechatronics when a DSG7 has been stationary for prolonged storage such as world shipment when new or storage in a dealer pound. The effect of the valves sticking means loss of drive engagement.

The reason on the web that 37G7 is associated with gearchange characteristics is because as with all software, you have one standard. In loading the "Service Campaign 37G7" (newer software standard), all other previous modifications will be loaded. So as a consequence, DSG7spd built prior to July 2010 will see a change in gear change points in D1,D2 & D3. Those built after July 2010 will not see a change as its was already "built in" on the production line.

And the Clutch pack is separate set of issues, not to be confused with the above. Just it may for some, that their circumstances when having the clutch pack resolved, invokes the Service Campaign 37G7 which is exactly what is suppose to happen at the dealership if hooked up to the diagnostics it prompts the action is outstanding.

As before, can't help further unless you put up your gearbox standard from a VCDS Autoscan file like this...........

Address 02: Auto Trans Labels: 0AM-300-04x.lbl
Part No SW: 0AM 300 053 HW: 0AM 927 769 D

- Or a screen capture from VCDS like this.........
Its not comprehensible as you already have the necessary change at the factory build.

C.

Thankyou for clearing that up
By the way mine rattles it head off going over a bumpy road also, sounds like a bag of spanners.
Not sure if the new uprated clutch pack will solve that issue.??
Cheers.

Clutch pack will address that.

C.

Do you think it will
Be so pleased if it did.
Cheers.

I knew it that the annoying sound was because the 3rd gear is pre-selected without load and it ''plays'' around with the teeths of the main shaft of the Gearbox ..
But why the DSG6 gearbox which has almost the same operation has no rattling noises?

Also here in Greece ALL DSG7 Have the same sounds from the DSG7 (we have very bad roads in the town so in D2/D3 you can hear it) with the latest update and again they hear the sounds AGAIN ....
And you buy a car that it cost 22.000 euro+ and you are not waiting a new car to do like a old car(i knew before i buy it that it will makes these sounds , because i read it at the net)

Sorry for my bad English

You are making too much of a simple comparison. They may be similar-ish but 6 speed is built differently in detail to the 7 speed.
C.

I see the pictures , ok
I mean that the DSG6 works like DSG7 , Both DSG when they have D2 they have preselect the D3 . In DSG7 The 3rd gear's teeth when you are in bad roads due to inertia (hope to write it correct) touch the teeth of the main shaft so you we hear the CRACKING noise .
In dsg6 i think that it does the same , but you can hear nothing
